Weinstein A.BACKGROUND 4DOS provides a way of attaching descriptions to files on your disk that is apparently seamless. The descriptions appear on directory displays and automatically are copied when you COPY or MOVE a file to another disk or directory. But this seamless property fails as soon as you use other programs on your files. For example, if you archive the files with the PKware programs PKZIP or PKUNZIP, the descriptions stay behind. 4ZIP and 4UNZIP address this problem, providing an automatic method to store descriptions in ZIPFiles and to restore them when you extract a file. You should know that the DESCRIPT.ION file is a hidden file. You will not see it in the DOS directory unless you change the file attribute or use the 4DOS DIR /h option. You must have copies of the PKware utilities located on the DOS Path, or in the current directory. These shareware programs are not supplied with 4ZIP/4UNZIP. You can obtain them from many Shareware distributors, BBS's or from PKware directly at: PKware Inc. 7545 North Port Washington Road Glendale, WI 53217 XD Systems is not affiliated with PKware in any way. B. 4ZIP USAGE 4ZIP Usage is: 4ZIP ZIPFILE [Options] [d:][path][filespec] [filespec] [..] ***OPTIONS*** /a ZIP all files matching filespecs without query /m Move selected files from source directory to the ZIPFILE /odeinsu Order by Date created Ext descrIption Name Size Unsorted {-bekoqs!3$} Pass these commands on to PKZIP A directory display similar to that of SELECT will appear showing all of the files meeting any of the filespecs. This use of include lists is like the 4DOS DIR and SELECT usage. Filespecs can freely use the wildcard characters '*' and '?'. For example the filespecs c:\wp\*smith*.*; *. xyz would display all the files in the c:\wp directory that either have the letters smith in the name part or have xyz as the extension. Note that only the first argument in an include list can have a pathname; subsequent arguments default to the 2 same path. Filespecs in an include list can be separated by ';', as in 4DOS, or, for convenience, '+' or ' '. You can mark files to be ZIPped into ZipFile in several ways, using the keyboard or mouse, similar to the 4DOS SELECT command, as follows: Mark <+> <INS> UnMark <-> <DEL> Toggle <SPACE> <Left Click> Toggle All <*> <CTRL ENTER> Begin Block <F7> <CTRL K B> End Block <F8> <CTRL K K> To move the selection bar around the list of files, use the cursor, the mouse, or the following keys: <UP> Up one line <DOWN> Down one line <PGUP> Up one full screen <PGDN> Down one full screen <HOME> To top of list <END> To bottom of list Additional functions are: <F1> Display Help screens <ENTER> ZIP marked files into ZIPFILE <ESC> <Right Click> Quit 4ZIP without doing anything 1.Options a. Sorting 4ZIP will allow you to control the order in which files are displayed and zipped. The syntax is: /o[deinsu] Order by Date created Ext descrIption Name Size Unsorted b.International Date and Time 4ZIP/4UNZIP now is consistent with your country=xxx command in config.sys. Commandline overrides for the time format are provided. They are: /24 Use 24 hour time /12 Use 12 hour time (e.g., 10:35p) 4ZIP has two options which can be used singly or together, e.g., /a /m, or /am. 3 /a ZIP all files matching filespecs without query. 4ZIP Junk /a C:\SOURCE\*.Pas + *MATH*.INC would ZIP into JUNK.ZIP all files from the C:\SOURCE directory that either had the extension PAS or the extension INC and MATH anywhere in the filename. /m Move selected files from source directory to the ZIPFile. This works by deleting the files from the source directory after ZIPping. c. PKZIP Command Options 4ZIP will accept the following subset of the PKZIP commands and will pass them on to PKZIP: 'b', 'e', 'k', 'o', 'q', 's','!','3','$'. You'll have to read the PKZIP documentation to learn the meaning of these options. To pass commands to PKZIP, just enclose them in curly brackets anywhere on the 4ZIP command line. For example: 4ZIP myfiles {-o -es -!} *.txt or 4ZIP myfiles {-o} *.txt { -es -!} would both pass the commands -o -es -! to PKZIP. Some of the other PKZIP commands (e.g., '@', or 'f') are not compatible with 4ZIP and would mess up the tracking between files and their descriptions. 4ZIP will ignore these options if you try to use them. IF you use a PKZIP configuration file, make sure that you do not try to pass commands that would not be acceptable on the 4ZIP command line, as unpredictable results will occur, mainly mismatching descriptions with the files. d. Help Key F1 The help screens are displayed anytime F1 is pressed. Running 4ZIP with an error on the command line automatically invokes the help display. 4 C. 4UNZIP USAGE 4UNZIP Usage is: 4UNZIP ZIPFILE [Options] [outpath] [d:][path][filespec] [..] The display is similar to the 4ZIP display, showing all the files in the ZipFile that meet any of the filespecs. Marking of the files to be extracted and cursor movement around the screen is identical to 4ZIP. 4UNZIP has several options. The first two are similar to the ones provided for 4ZIP. /a UNZIP all files matching filespecs without query. /m Move selected files from the ZIPFile to the outpath directory (Current directory is default). /d Delete selected files from the ZIPFile without extracting. This provides a convenient tool for ZipFile management, allowing you to select files to be removed using any combination of filespecs with wild cards and the SELECT screen. The combination /ad will delete all the specified files without presenting the SELECT screen. The combination /md is interpreted the same as /m alone. Outpath, if supplied, determines the directory in which the extracted files are to be placed. So for example 4UNZIP C:\SOURCE\JUNK A:\ /am *.doc would extract all of the files with extension doc from the file C:\SOURCE\JUNK.ZIP and place them in the root directory of the A: drive. Then it would delete all of these files from JUNK.ZIP. 4UNZIP also accepts a subset of the PKUNZIP commands, using the same syntax as 4ZIP. The commands that 4UNZIP will recognize are: 'c', 'p', 'q', 's'. D. EXTENDED DESCRIPTIONS 4DOS 4.0 has capacity for descriptions up to 80 characters in length, and has a system for developers to extend the des- criptions to even greater lengths or to store other file- related information. However, the PKZIP comment format has room for only 59 characters. 4ZIP and 4UNZIP are designed to save and restore file descriptions up to the full length of 80 characters, and will also capture and restore any extended description fields if present. This all happens automatically. How it's done -- The PKZIP directory structure allows for file descriptions of only 59 characters. If all the Zipped files have descriptions that will fit and there are no extended fields in their 5 descript.ion entries, then the descriptions are stored in the PKZIP file directory, as in previous versions of 4ZIP. Otherwise, truncated descriptions are stored in the PKZIP directory, so they can be seen without 4UNZIP, and a special file with name 4ZIP_xxx.xxx (where the x'es are random letters) is added to the ZipFile, containing the full descript.ion entries. If the ZipFile is added to, more than one of these files may be present. You will see these files listed on the screen by PKZIP, but otherwise you should ignore them. E.

It used batch files to drive 4ZIP and 4UNZIP and could only run under 4DOS. Ver 0.91 (Beta Test) 12/20/89 4ZIP and 4UNZIP now stand alone, and can be run under DOS. 4UNZIP accesses the ZipFile Directory itself without using PKZIP -v. This is much faster. Ver 0.92 (Beta Test) 1/21/90 Improved exception handling for DOS errors. Added /d and /m options to 4UNZIP Allow specification of destination path for the extracted files in 4UNZIP Ver 0.93 (Beta Test) 2/04/90 1. Changed mark/unmark in 4ZIP and 4UNZIP to be more like the latest SELECT. Space bar toggles mark and * marks all. 2. 4ZIP lost descriptions on some files in big directories. Now fixed. 3. Ver 0.92 of 4ZIP tried to correct command line parser so that C: ==> C:*.* and ABC ==> ABC\*.* if ABC is a directory but ABC.* otherwise. Got it right this time! Version 1.0 3/11/90 First public release Version 1.01 3/21/90 1. Corrected error (shame on me) in 4UNZIP that included marker in filename. 2. Corrected 4UNZIP error when destination path is not source path. 3. Minor changes in documentation. Version 1.02 3/23/90 Corrected error in 4ZIP and 4UNZIP - not properly recognizing include lists. Version 1.03 4/01/90 Changed file access to run on networks reliably. Added name and serial number on registered copies. Version 1.04 6/10/90 Modified to correct for 4DOS 3.0 quirk. Entries in DESCRIPT.ION are sometimes delimited by LF instead of CRLF. Earlier versions of 4ZIP/4UNZIP misread these lines. Corrected 4ZIP/4UNZIP to properly access ZIPfiles smaller than 150 bytes. Version 1.05 7/15/90 Corrected error that caused -a option of 4UNZIP to lose descriptions. 7 Version 1.06 8/03/90 Added Error Messages for Drive unready and Disk write-protected. 4ZIP JUNK a: is now equivalent to 4ZIP JUNK a:*.* Version 1.07 9/16/90 4UNZIP choked on the long ZipFile comments now being added by some BBS operators. Modified to correct this. Version 1.08 10/18/90 4UNZIP occasionally dropped file descriptions if the file had an 8 character name and a 3 character extension. This is corrected. A problem with include lists that caused the same file to be selected more than once has been corrected for both programs. For example, 4ZIP test *.txt+4*.txt would show the file 4zip.txt twice. Version 1.09 6/22/91 4ZIP would prevent PKZIP from updating an existing ZIPFile if the DOS SHARE program was loaded. This is corrected. Version 2.0 10/13/91 This is an extensive revision, including Help key, mouse compatibility, Passthrough of PKZIP and PKUNZIP options, sorting of the display in 4ZIP, and International dates and time. Version 2.01 12/14/91 Both 4ZIP and 4UNZIP set the display blinking attribute off and did not restore it. This is now fixed. 4UNZIP occasionally lost descriptions existing in a directory. Also fixed. G. 4EDIT In 1988, I wrote and distributed a shareware program, XDIR, which was one of the first DOS directory programs to attach a comment to each file. When I first saw 4DOS, I loved it, but I wanted to have the same sort of full-screen editor for directory comments (or, in 4DOS terms, Descriptions) that I had in XDIR. 4EDIT provides this feature. I think you will find it very useful. Its good practice to comment your files, and often it is handy to see the descriptions attached to other files, while you are writing a new one. The 4EDIT package is shareware, available on Bulletin Boards, CompuServe, and from shareware distributors. Registration is $15. See the order form at the end of this manual. 8 SOFTWARE REGISTRATION FORM AND ORDER Check all that apply: [ ] 4ZIP/4UNZIP registration _____ @ $15.00 [ ] 4EDIT registration _____ @ $15.00 Postage and Handling $3.00 TOTAL ENCLOSED: $______ If you already have copies of the programs you are ordering , where were they obtained?
