But most of the known compression programs are working only with the command line. I think this operating on the command line in a frequent work is unpractical. And that's why I tried to create a program to operate archives. This program works with archives of the best archiver I've ever seen - ARJ by Robert K. Jung. Some of the main abilities of the ARJVIEW 1.30 are: - Decompressing algorithms are built in the program in order to make the program faster. - The environment of the program is similar to the environment of the Viewers from Norton Commander 3.9. - You can simply choose the files you want to extract. - Testing function to check integrity of files stored in archive. - Viewing function to view selected file in the appropriate viewer of the Norton Commander 3.0. - Deleting function to delete selected files from the archive. - Viewing function for the archive and file comments. - Database function to create a simple database file with some handy informations about each file from the archive. - Report function to create a raw ASCII list of names of selected files. - Reread function to change to another volume (disk) or another archive. - Order function to sort files on the screen by name, extension, size or time. - Full mouse support. 1.1. HARDWARE AND SOFTWARE REQUIREMENTS The ARJVIEW program is designed for IBM PC's and compatible computers with processors 8088, 8086, 80286, 80386 and i486. MS-DOS 3.0 or later is required and Norton Commander 3.0 is highly recommended. The Norton Commander is not necessary in order to work with ARJVIEW, but significantly improves use of this program. This program drives the hardware of the display adapter directly, so this program won't work in the remote mode on local networks. In order to operate this program without memory problems I recommend at least 200KB of the free conventional memory. You may also need any version of the ARJ program by Robert K. Jung. This program is not necessary, if you have already some ARJ archives created. ARJVIEW 1.30 - page 04 1.2. USER SUPPORTED SOFTWARE This program is a shareware program for personal use. If you want to use this program after reasonable evaluation period, send a registration order to the following address: Jakub Jelínek Mezivrsí 35 147 00 PRAGUE 4 CZECHOSLOVAKIA To do this use the registration form from the special file ARJVIEW.FRM or, if you are a Czechoslovak citizen, from ARJVWCS.FRM. This form includes pricing informations. Making copies of the ARJVIEW program for other or uploading to electronic bulletin boards (BBS) is allowed and you are encouraged to do this as long as is the program transferred in his entirety and without any modifications. If you would want to upload ARJVIEW to your favorite BBS, use please the original file ARJVW130.EXE in that shape you received them. 1.3. CONTENT OF THE ARJVW130.EXE ARCHIVE The ARJVW130.EXE is the self-extraction form of the ARJ-type archive. This archive contents the following files: - ARJVIEW.EXE ; ARJVIEW program file - ARJVIEW.DOC ; This User's Manual - ARJVIEW.FRM ; Registration form for ARJVIEW - ARJVWCS.FRM ; Registration form for Czechoslovak citizens only 1.4. MODIFICATION HISTORY In ARJVIEW 1.30 were added and improved following functions: - Added empty directories support. - Added backup type of archives support. - Added summary line for the whole archive with the sum of all lengths, etc. - Added Order function to sort files on the screen. - Fixed bug with testing in archives, that have more than 128 files. - Fixed handling with zero length files. In ARJVIEW 1.21 from December, 15th, 1991 were fixed these bugs: - Fixed bug in handling with more than 128 files in the archive. Now is ARJVIEW operating well with all ARJ archives with up to 500 files. - Fixed bug in the PgDn movement. - Fixed archive position displaying in 43, 50, 60 lines modes. - Fixed bug with displaying of some comments. ARJVIEW 1.30 - page 05 In ARJVIEW 1.20 from November, 19th, 1991 were added and improved following functions: - Significantly speeded up displaying. - Added viewing function for archive and file comments. - Added support of high display modes for EGA, VGA and SVGA adapters, i.e. support of 80x43 and 80x50 modes known in Norton Commander as 'EGA lines'. - Significantly improved the program help. In ARJVIEW 1.16 from October, 6th, 1991 were added and improved following functions: - Significantly improved and speeded up reading of SFX (self-extracting) archives (.EXE extension). - Speeded up viewing of files using external viewers. - Significantly revised documentation. - A lot of internal improvements. In ARJVIEW 1.15 from July, 7th, 1991 were added and improved following functions: - Added DataBase function for creating a DBF file with some handy informations about each file stored in the archive. - Added List function for creating a raw ASCII list of file names from the archive. - Fixed problem with extracting and viewing of files with the size less than 512B. - Improved design of dialog boxes during breaking of process. - Changed the default button in the query on overwriting from SKIP to OVER. ARJVIEW 1.14 from June, 20th, 1991 was the first public version of this viewer. 2. GETTING STARTED I assume you received a copy of self-extracting archive ARJVW130.EXE. Run this program in order to get all ARJVIEW files (program file, this file and both order forms) in the current directory. To run the ARJVIEW program simply enter ARJVIEW [archive]. If you enter only ARJVIEW <ENTER>, you'll get the following message: ARJ View 1.30 Copyright (c) 1991,1992 Jakub Jelínek Usage ARJVIEW archive[.arj] ARJVIEW 1.30 - page 06 This message explains the syntax of the ARJVIEW program. Expression in square bracket is optional. 'archive' can include the whole pathspec, so if you want to view archive FIDONEWS.ARJ in the directory C:\FIDO, you will enter: ARJVIEW \FIDO\FIDONEWS or ARJVIEW \FIDO\FIDONEWS.ARJ because the extension of ARJ is the default extension. But if you want to view an self-extraction SFX archive with the extension of EXE, you'll have to enter both the name and the extension: ARJVIEW \FIDO\FIDONEWS.EXE If you have at the moment no one ARJ-type archive available, you can try all the functions of the ARJVIEW program on the distribution archive ARJVW130.EXE (rather on the backup copy of'em, if you want to try the deleting functions). You'll simply enter on the command line: ARJVIEW ARJVW130.EXE and you'll get to the environment of the ARJVIEW program. 2.1. INSTALLATION If you are an owner of the Norton Commander 3.0, you can install ARJVIEW as a standard viewer for all ARJ archives. The installation is very simple. Run Norton Commander 3.0 and add the following line to the very end of the extension file in Norton Commander (NC.EXT). In order to edit this file press sequentially the following keys: F9 C X Than add this line below all other lines: A??: ARJVIEW !:!\!.! Be sure all extensions in the extension file, that begin with the A letter, are in NC.EXT before this extension (e.g. ASM). Then press Shift-F10 to save this extension file and quit editing. Than edit your AUTOEXEC.BAT file and add the path to ARJVIEW.EXE to the PATH statement. Make sure, that ARJVIEW.DOC is in the same path as ARJVIEW.EXE (it is needed for the 'Manual' function). Now, whenever you click the left mouse button or press ENTER on the ARJ archive (and also on all other ARJ volume extensions, i.e. A01 to A99), you'll get to ARJVIEW. See Norton Commander 3.0. manual for additional informations on extension file. ARJVIEW 1.30 - page 07 3. OPERATING ARJVIEW Operating of the ARJVIEW program is similar to the operating of other Viewers supplied with Norton Commander 3.0, e.g. WPVIEW.EXE or DBVIEW.EXE. If you are able to work with WPVIEW, you'll be certainly able to operate ARJVIEW as well. The most of the program functions can be accessed either via keyboard, or via mouse, except 'Select' and 'Unselect' a group of files functions, that can be accessed via Gray + or Gray - only. But this selection can be done with mouse as well, if you want to select files sequentially. 3.1. MOVEMENT CONTROL If you are in the ARJVIEW environment, you can use following keys in order to move among the files stored in the archive: ┌───────────────────────┬──────────────────────────────────────────────────┐ │ up and down arrow │ Moves the inverted bar (current file) one file │ │ │ up or down. │ ├───────────────────────┼──────────────────────────────────────────────────┤ │ PgUp, PgDn keys │ Moves the inverted bar one page up or down. │ ├───────────────────────┼──────────────────────────────────────────────────┤ │ Home, End keys │ Moves the inverted bar to the first or to the │ │ │ last file in archive. │ ├───────────────────────┼──────────────────────────────────────────────────┤ │ left mouse button │ Moves the inverted bar to the file, to which is │ │ │ the mouse cursor pointing. │ └───────────────────────┴──────────────────────────────────────────────────┘ 3.2. SELECTING OF FILES You can select some files in archive or unselect these files in order to specify an argument for some functions described below. These functions work either with all selected files, or with the current file, if no one is selected. This behavior is related to F5 Rename, F7 Melt, Shift-F7 Melt.., F8 Delete and F9 Test. Functions F6 and Shift-F6 !require! some selected files in order to get a database or a list, that is not empty. ARJVIEW 1.30 - page 08 3.2.1. SELECTING OF SINGLE FILES The following keys and mouse button serve to select single files: ┌───────────────────────┬──────────────────────────────────────────────────┐ │ Insert key │ Toggles selection status of the current file and │ │ │ moves one file down. (Like 'Insert moves down' │ │ │ in Norton Commander 3.0). │ ├───────────────────────┼──────────────────────────────────────────────────┤ │ right mouse button │ If you just press the right mouse button, the │ │ │ program will toggle selection status of the file │ │ │ under mouse cursor. If you hold the the right │ │ │ mouse button and move up/down, all files you'll │ │ │ shift on will be either selected or not │ │ │ selected, depending on the selection status of │ │ │ the file you pressed the right mouse button on. │ └───────────────────────┴──────────────────────────────────────────────────┘ 3.2.2. SELECTING OF A GROUP If you press the Gray + key, you'll get a small dialog box with the query on the wildcard name of the group of files to be selected. The default specification is *.*, i.e. select all the files. The Gray - key is like Gray + key. The only difference is, that with Gray - you are unselecting a group of files. 3.3. FUNCTION KEYS Functions of ARJVIEW can be called using function keys or using the mouse in the function bar at bottom of the screen. Some of the functions are accessible via Shift key and function key only. 3.3.1. HELP FUNCTION - F1 key The help is longer than one screen, so you have to scroll using PgUp, PgDn, Home, End and up/down arrows or using the mouse. If you want to know more about any function, you can select Manual function in the Help dialog box. You'll see this manual in the text viewer. This manual has to be in the same directory as ARJVIEW.EXE. 3.3.2. INFORMATION RELATED TO THE CURRENT FILE - Shift + F1 key This function shows full filename including full path of the current file, original size, compressed size, ratio (compressed/original), type of the file, compression method, date/time of modification, archiver version, minimum version to extract (should be 1), operating system, garbling status, volume options, CRC (cyclic redundancy code), translation of the path in filename, backup flag. For meaning of these values please refer to the ARJ.DOC user's manual from the ARJ package. ARJVIEW 1.30 - page 09 3.3.3. MULTIPLE VOLUMES OPERATING - F2 and Shift+F2 keys This functions serve to the reading of next/previous volumes or other archives. If you press F2, you'll get a dialog box with the name of the current archive and extension of the next volume (e.g. .A01, if you are viewing .ARJ at the moment). Certainly you can edit the name, extension and/or path in order to read another archive. If you press Shift+F2, you'll get the same dialog box, but the extension'll be of the previous volume (for example .ARJ, if you are viewing .A01 at the moment). 3.3.4. VIEWING OF THE CURRENT FILE - F3 key The F3 function lets you see current file in the appropriate Viewer from the Norton Commander 3.0. These Viewers must be in the path of the PATH statement. If you haven't the Norton Commander, you'll have to copy/rename your favourite viewer to the names listed below. ┌─────────────────────┬──────────────────────┬──────────────────────────────┐ │ Name of the Viewer │ File extensions │ Type of files │ ├─────────────────────┼──────────────────────┼──────────────────────────────┤ │ PCXVIEW.EXE │ .PCX │ Pictures in ZSoft's format │ │ PARAVIEW.EXE │ .DB │ Database files from Paradox │ │ DBVIEW.EXE │ .DBF │ Database files from DBase │ │ REFVIEW.EXE │ .RXD │ │ │ RBVIEW.EXE │ .RBF │ │ │ ARJVIEW.EXE │ .ARJ .A01 - .A99 │ ARJ archives; you can view │ │ │ │ archives recursively │ │ 123VIEW.EXE │ .WK1 .WKQ .WKS .WKT │ Spreadsheet files from │ │ │ .WR1 .WRK .XLS │ Excel/Lotus │ │ WPVIEW.EXE │ any other │ Text/Hexadecimal Viewer │ └─────────────────────┴──────────────────────┴──────────────────────────────┘ If you encounter critical error during viewing, please look for the subdirectory named ~ARJ~VIE.~$~ in the current directory. If it exists, delete the whole content of this subdirectory and the subdirectory as well. Also remember, that it is better to start ARJVIEW from the disk with enough place, because ARJVIEW creates a temporary file on the current disk. Next version of ARJVIEW will have a setup in order to select the drive you want to store temporary files on. 3.3.5. VIEWING OF COMMENTS - F4 and Shift-F4 keys If you want to see the archive comment, press F4 and scroll in the comment. Scrolling keys are the same as in the F1 function. If you want to see file comment of the current file, just press Shift+F4 instead of F4. ARJVIEW 1.30 - page 10 3.3.6. CREATING OF A DATABASE FILE - F6 key If you want to make a database of files in the archive, select files to add to the database and press F6. The database file will be created on the same place as archive and with the same name, but with the .DBF extension. The database file contents following fields: FILENAME name of the file from archive ORIGSIZE original (uncompressed) size of the file COMPSIZE size of the compressed file RATIO COMPSIZE / ORIGSIZE DATE date of last modification TIME time of last modification CRC full 32-bit CRC (cyclic redundancy code) in hexadecimal format ATTR file attributes T file type (B - binary, T - text, D - directory, V - volume) P full path flag M compression method number G garble flag V files is continued on next volume X files is extended portion from previous volume COMMENT file comment (first 255 characters) If you press F6 with no files selected, you'll get empty database!! 3.3.7. CREATING OF THE FILE LIST - Shift-F6 key This function is similar to the previous, but creates a raw ASCII list .LST with names of selected files separated by CR/LF. 3.3.8. EXTRACTING (MELTING) OF FILES - F7 and Shift+F7 keys This function will extract selected files, or the current file, if no files are selected. You will be prompted for the destination path for these files. The path must be entered in DOS conventions. If any of the directories or subdirectories don't exist, you will be asked for the permission to create them. The only difference between F7 and Shift-F7 is, that in F7 are files extracted to one directory only, no matter on the path stored in the archive, but in Shift-F7 they are extracted with full path stored in archive. F7 is like 'ARJ e .......' command and Shift-F7 like 'ARJ x ...........' command. ARJVIEW 1.30 - page 11 3.3.9. DELETING OF SELECTED FILES FROM THE ARCHIVE - F8 key This function deletes selected files (or current file, if no one is selected) form the archive. You'll be asked for permission to delete these files. Be sure you have enough disk space on the disk the archive is stored on, because ARJVIEW creates the temporary file at the same place as archive. Future versions will have an option to select the disk for temporary files. If you encounter an critical error during deleting (I hope it won't be very common), please look for the files named ~ARJ~VIE.~_~ and ~ARJ~VIE.~_1 in the directory of the original archive. If there are these files, the larger one will be probably the original archive and the shorter one will be the archive with some deleted files. 3.3.10. CHECKING OF FILE INTEGRITY - F9 key Function F9 is used to check the integrity of selected files or of the current file, if no one is selected. It compares the stored 32-bit CRC with the real CRC of the file. If it find an error, you will be warn about them. This function is just extracting to the memory only, so it is much faster and you won't need free disk space to check the integrity of the files. 3.3.11. FILE SORTING ON THE SCREEN - Shift+F9 key This function was added to simplify searching and selecting of files. You will choose one of the sort modes and all files from the archive will be sorted on the screen. Sorting modes are following: by filename (descending or ascending order) by extension (descending or ascending order) by original length (descending or ascending order) by time (descending or ascending order) original order (as stored in the archive) 3.3.12. END OF WORK WITH ARJVIEW - Esc and F10 keys If you want to quit this program, press either Esc or F10 key while not in the dialog box. The screen will become it's previous state.

FLAGS Flags are short parameters of files. In the picture are they written as btpmgvx. Each of this letters is substituted by one character as follows: b backup type flag (improvement in ARJ 2.30, see ARJ.DOC) possible values: * file is a backup copy BLANK file is not a backup copy t type of the file possible values: B binary type T text type ? unknown type D directory V volume label p full path flag possible values: + file has the full path stored in the archive BLANK file has not the full path stored in the archive m type of the compression possible values: 0 file is stored 1 full (maximal) compression 2 slightly less compression 3 less compression 4 fastest compression g garble flag possible values: G file is garbled BLANK file is not garbled v volume flag possible values: V file continues on the next volume BLANK file ends in this archive x extended flag possible values: X file is an extended portion of the previous volume BLANK file begins in this archive ARJVIEW 1.30 - page 14 4.1.2. FILE ATTRIBUTES Each of the letters in ashr from the format line is substituted by one character as follows: a archived file possible values: A file has the archived bit set - this bit is cleared s system file possible values: S file is a system file - file is not a system file h hidden file possible values: H file is hidden - file is not hidden r read only flag R file is read-only W file is not read-only 4.1.3. OTHER FILE RELATED INFORMATIONS Through the format line in 4.1. are used following letters and expressions. They will be replaced by: d any decimal digit e any hexadecimal digit FILENAME is the 8 characters long filename EXT is the 3 characters long file extension Ratio is the value of Compsize / Origsize. It means, that a ratio of 0.151 is quite good compression factor, but 1.000 is a zero compression (storing). 4.2.

TERMINOLOGY ARCHIVE This is a file containing one or more files in a compressed or non-compressed state and containing file related informations such as filename and date-time last modified, etc. FREEZING The process of encoding redundant information into data requiring less storage space. MELTING The processing of recreating the exact information that was previously compressed. RATIO The percentage compression reported by ARJ is a variation of one of the TWO standard methods of expressing compression ratio in the technical literature. ARJ uses Compressed size / Original size ratio. The other method is the inverse ratio. When ARJ reports 96% as the compression ratio, it means, that the compressed file is 96 percent of the original size (very little compression). Other archivers use their own methods. LHA by Haruyasu Yoshizaki uses the same ratio as ARJ.
