******************************************************* | RO-SOFT SYSTEMS (C) 1993 | |=====================================================| | DISK UTILITIES Ver 5.0 BY Robert Ossowski | ******************************************************* * MAKE YOUR COMPUTING EASY * _______ ____|__ | (R) --| | |------------------- | ____|__ | Association of | | |_| Shareware |__| o | Professionals -----| | |--------------------- |___|___| MEMBER Table of Contents : Page Version Upgrades ............................... 1 Permanent sort & compact directories SORTDIR.COM 2 Disk scan routine SCANDISK.COM ................. 2 Disk clean up routine DSKCLN.COM ............... 3 Disk optimiser routine DEFRAG.COM .............. 4 File recovery routine UNDELETE.COM ............. 7 Repeat command in all directories REPTCOMM.COM . 8 Double directory list/print/all dirs DDIR.COM .. 9 Disk directory tree report TREE.COM ............ 10 File find list/print WHERE.COM ................. 11 These routines have been tested under DOS Versions 3.1 thru 5.0, on 5.25 and 3.5 inch floppies, and on hard disk partitions up to 1 Giga Bytes. Maximum directory size is 1024 entries. Page 1 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * Version 5.0 Upgrade * Increased functional disk partition size from sixty-seven Mega Bytes to one Giga Bytes. Added new Function CLNDSK.COM which will clean up all unused disk space. * Version 4.7 Upgrade * All programs have been changed to .COM type execute modules and are now being distributed in a compacted form for fast load and low storage requirements. * Version 4.6 Upgrade * Bug fix for names beginning with ascii codes greater than 0E5h (229) in DEFRAG.COM and SORTDIR.COM. In previous versions, a name such as that, would cause a null entry to be inserted in the directory causing DOS to think it was the last entry. All utilities have a new function added for user customized screen display colors that may be permanently stored in the .COM file. Entering "Alt & F9" from entry prompt takes you to the following screen : ENTER SELECTION TO SET NEW DISPLAY COLORS : «A» Screen color «B» Message color «C» Edit Window «D» Screen border ESC = Abort edit, F10 = Save edit changes The selection listing will be in the current color. When you enter a selection letter that line is highlighted and the following message appears : Up & Down arrows change text, Left & Right arrows change background As you press the arrow keys the selected entry is displayed in a new color. Pressing "Esc" or "Return" takes you back to the select line. After you have set the colors press the "F10" key to store changes. Then press the "Esc" key to return to the prompt screen. Page 2 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * SORT DISK DIRECTORIES * * SORTDIR.COM * This utility inputs a drive letter and directory name for sort first by filename, & then by file extent. It loads and sorts the directory, clears out all deleted entries, then stores the sorted directory on the disk. The global character * may be used in order to have all the directories on a drive sorted. Program sign-on prompt is as follows : Enter DIR Name ? Entry Format : d:\dirname (ie. c:\mydir) d:* For all dirs on drive d:\ For just root dir Directories will be sorted and compacted * SCAN A DISK FOR READ ERRORS * * DISKSCAN.COM * This routine will check the readability of an entire disk partition. It first checks the file allocation table for any disk clusters marked as bad and reports any found. Then it starts at sector zero, reading the disk in 64K byte blocks. If a read error is detected, it will report the error type returned by DOS and begin checking that area one sector at a time. At any sector returning an error, the file allocation table is checked for the recorded status and a message is displayed (i.e. Flagged as bad, Un-allocated, or In -use by file). If the sector is in a reserved area, a message indicat- ing so will be displayed(i.e. Boot sector, Root directory, File alloc table). At completion of this sector by sector search it will cont- inue search in 64K blocks to the end of disk partition. No attempt is made by this routine to correct any errors found. Its only function is to give the error report. Command options may be entered at run time or the program will prompt you for an input. Options format is (drive:/P(n)), where drive is the assigned disk letter, /P = Output errors to printer, (n) =1 or 2 for Lpt1 or Lpt2. Page 3 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* ■ CLEANDSK.COM ■ This routine has four functions available for cleaning up your disk data. You may select any or all using the following option switches. Enter as (drive letter:/opt1/opt2/opt3) to perform selected options or (drive letter:/a) or (drive letter:) to perform all four functions. ■ /F ■ Fill all unallocated disk space with "0" or "text string". This function writes to all unused disk sectors. ■ /E ■ Fill the area of end file blocks not used with "0" or "string". This function reads in the last block of every file, fills the portion not used by the file, and writes cleaned block to disk. ■ /D ■ Remove all deleted directory entries. This function reads in all dirs and sub-dirs, removes deleted entries, and writes new directory to disk. ■ /S ■ Sort and store sorted directories. This function reads in all dirs and sub-dirs, sorts the dir- ectory entries first by name, then by extent, to get the most logical listing, and writes the new directory to disk. ■ /A ■ Perform all four functions. The following is the entry prompt screen : ■ RO-SOFT Systems Clean Disk Function (c)1993 ■ To fill unused disk data storrage areas with selected string This function leaves all file data unchanged Drive and Options ? ................................................ Entry format : d:/opt/opt "text string" /f to Clean Free Space /e to Clean End of File Sectors /d to Remove Deleted Directory Entries /s to Store Sorted Directories /a for All Four Options (Default) "desired text string for fill" Press "Alt & F9" to set new color, "F1" help, or "Esc" to exit ! Page 4 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * DISK OPTIMIZER DEFRAG.COM * * DEFRAG.COM * This routine will correct fragmented data files on your disks,allowing most applications to run much faster on your system. The present version works on all files in directories no more than five dir levels deep from the root directory. Any Files or Dirs beyond the fifth level will hinder defrag and disk pack operations. Directories with over 1024 entries will be by-passed. Maximum hard disk partition has now been increased to one Giga Bytes. Command options may include a drive letter and a /P or /P2 (i.e. d:/p). This should be run about once a week to keep your files in good shape. The /P option invokes a more intensive data storage compression cycle. This option shifts data to fill all unused disk clusters leaving all free space in one area at the end of disk. This option takes quite a while to complete. Use of these options are only necessary if normal defrag cannot clear all file fragments. The /P2 Option adds another check to the pack cycle for use on nearly full disks with a lot of fragmentation. You should not norm- ally need to use this option. The map option displays the status of all disk clusters and highlights any breaks in cluster strings. The sign-on screen prompting for drive & option entry is as follows : To defragment files on a disk Enter new drive ? ................................ Entry Format : drive:/p (ie. c: or c:/p for drive c) Add the /p for badly fragmented drives ! BACK UP YOUR FILES BEFORE RUNNING DEFRAG ! Press "Esc" to exit ! Page 5 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * DISK OPTIMISER DEFRAG.COM * After entering drive & options, data for all directories on the disk is being read while displaying the following screen : Checking Dir : C:\TASM\WORK * Getting Disk Data * Press "Esc" to abort optimization The displayed directory name changes as each dir is scanned for fragmentated files. When this scan is completed, the results are displayed on screen as follows : 542 File Fragments Detected Press "M" for allocation map, "C" to continue, or "Esc" to exit At this prompt, you may select "M" to display the disk cluster mapping of the results of the scan, "C" to continue into the defragging process, or "Esc" to abort the program. On entering "C", the directories on the drive are sequentially evaluated, and fragmented files are moved to a new location. At the completion of each directory cycle, if you entered the /P option, a data compact cycle is initiated. This frees up blocks of sequential clusters to relocate more fragmented files. As this process continues, all file segments being moved will be displayed on-screen with the present cluster location first,and then the new cluster to which that file segment is being moved. Pressing the "Esc" key will interrupt the cycle at any time. Upon exiting, a new check is made for file fragments remaining and is displayed. The program may be run again at any time to continue the process. Page 6 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * DISK OPTIMISER DEFRAG.COM * * DISK ALLOCATION MAP LISTING * When you select the disk mapping option all disk cluster allocation will be listed on screen, starting with the first page. The clusters where a file break occurs will be highlighted so you can see the shape your disk data is in. You can page back and forth through this listing. Each four digit entry is a hexadecimal number defining the location of the next cluster of data for this data block. Clusters in numeric sequence indicate an unbroken block of data. A "FFFF" entry indicates the last cluster of data in a particular file. The first entry on the first page is a disk type ID entry. This allocation table is called a "FAT TABLE". FAT stands for (File Allocation Table). Disk C: File allocation clusters 0000 h - 00FE h All entries in hexidecimal 2,048 Bytes per cluster FFF8 FFFF 0003 0004 0005 0006 0007 0008 0009 000A 000B 000C 000D 000E 000F 0010 0011 0012 FFFF 0014 0015 0016 0017 0018 0019 001A 001B 001C 001D 001E 001F 0020 0021 0022 0023 0024 0025 FFFF FFFF 0028 0029 002A 002B 002C 002D 002E 002F 0030 0031 0032 0033 0034 0035 0036 0037 FFFF 0039 003A 003B 003C 003D 003E 003F 0040 0041 0042 0043 0044 0045 0046 0047 0048 0049 004A FFFF 004C 004D 004E 004F 0050 0051 0052 0053 0054 0055 0056 0057 0058 0059 005A 005B 005C 005D FFFF FFFF FFFF FFFF FFFF FFFF 0064 FFFF 0066 0067 0068 0069 006A 006B 006C 006D 006E FFFF 0070 0071 0072 0073 FFFF 0075 0076 0077 0078 0079 007A 007B 007C 007D 007E FFFF 0080 0081 0082 0083 FFFF 0085 0086 0087 0088 0089 FFFF 008B 008C 008D 008E 008F 0090 0091 0092 0093 0094 0095 0096 0097 0098 0099 009A 009B 009C 009D 009E 009F 00A0 00A1 00A2 00A3 00A4 00A5 00A6 00A7 00A8 00A9 FFFF 00AB 00AC 00AD 00AE 00AF 00B0 00B1 00B2 00B3 00B4 00B5 FFFF 00B7 00B8 00B9 00BA 00BB 00BC 00BD 00BE 00BF 00C0 00C1 00C2 00C3 00C4 00C5 00C6 00C7 FFFF 00C9 00CA 00CB 00CC FFFF 00CE 00CF 00D0 00D1 00D2 00D3 00D4 00D5 FFFF 00D7 00D8 00D9 00DA 00DB FFFF 00DD 00DE 00DF 00E0 00E1 00E2 FFFF 00E4 00E5 FFFF 00E7 00E8 00E9 00EA 00EB 00EC 00ED 00EE 00EF 00F0 00F1 00F2 00F3 FFFF 00F5 FFFF 00F7 FFFF 00F9 FFFF FFFF 00FC 00FD 00FE 00FF 0100 ■ FFFF = File end cluster ■ FFF7 = Cluster marked bad ■ ???? = Next cluster in string File breaks are highlighted ■ 0000 = Unallocated cluster First entry is disk type ID Press Page-Up, Page-Down, or Esc to exit Page 7 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * RECOVER DELETED FILES * * UNDELETE.COM * This utility attempts the restoration of previously deleted files. It searches all directories of the current drive for a matching an entered filename. If a file is found,it marks it undeleted and assigns succeeding unallocated FAT entries, starting with assigned file beginning cluster, to this file. This may, or may not, make the file usable. If no files have been moved on the disk since this file was deleted it should then be a usable file. If a name is not entered, all deleted files and directories on current or specified drive will be displayed to mark for recovery as you see fit. The Probability of recovery is checked and listed as Good, Fair, Poor, or None. Sign-on prompt is as follows : Enter Filename ? Entry format to recover deleted files For a specified file : d:\filename.ext (i.e. c:\myfile.txt) To select from list : "Enter" (current drive) or "c:" (drive c:) All directories on disk will be searched Press -Esc- To Exit !

It is useful for clean up of misc. un-wanted files, or as suggested on sign-on, getting a printed list of all files on a drive using a dir command. If not an internal DOS command, the directory location of the command file must be in the DOS search path as set in your AUTOEXEC.BAT file. The sign on prompt is as follows: To execute a command in all directories on a drive Enter COMMAND ? .......................... Entry format : [/command] for current drive [drive:/command] for new drive Command will be executed in all directories on specified drive [ie. c:/ddir /p] To print listing of all files on drive C Remember that directory of ddir must be in the DOS search path Page 9 ********************************* * DISK UTILITIES BY RO-SOFT * ********************************* * DOUBLE COLOR DIR LIST/PRINT * * DDIR.COM * This routine prints and or lists a disks directories in double column format, pausing for user input at each page end unless the print option,/p was entered. If run from the DOS prompt, you may enter the drive and path as a command option (i.e. ddir d:\newdir). All file names, listed or printed, are first sorted by name, then by extent. If you have a color monitor, the different extents will be displayed in different colors. To run, enter the command (DDIR option). See option format below. If no command option is entered, the program will prompt you for an option entry. The option may contain the disk drive designation, the desired directory pathname, a /p to print, or a /# for all dirs on the drive. Just pressing the "Enter" key at prompt, will list only current directory. Filenames may be entered in the PATH using DOS wildcard characters * and ?.

If more than one screen page is found, it awaits user input to go to the next page. The file pathnames may be up to ninety-five characters long,and ten levels deep from the root directory. You may enter the filespec at the command level, or the program will prompt for an entry. The filespec should contain a filename, and file extent as required. Any KNOWN letters of the name, and wild card char- acters may be used. The "?" may be substituted for any unknown char- acter. The "*" indicates ALL for either name or extent. The command options may be a drive letter followed by a colon, and a single digit number. The number designates how many drives to search, starting at the input drive letter. Entering /p at the end of the command option will cause the search results to be listed and printed. Entries may be as follows : * *.dat A:4/p * List,& print all files with .DAT ext. drives A: thru D: * dat.* D:1 * Find & list all files with name DAT on drive D: * dat?????.* * Find & list all files beginning with DAT * da???.* * List all files with a five letter name starting w/DA * Default searches up to 10 drives starting with drive C: Enter search command or "Esc" to exit * WHERE.COM * This is a sample listing supplied by this routine Searching for file : *.DAT C:\CIM\FAVORITE.DAT 375 8-29-91 7:43p C:\SHARE32\SHELLHLP.DAT 39,791 6-27-91 8:23a C:\SHARE34\SHELLHLP.DAT 43,598 8-29-91 1:15p C:\TASM\SHELL\SHELLHLP.DAT 43,598 8-20-91 2:18p C:\TASM\WORK\ASCII.DAT 26,621 6-25-90 5:57p C:\TASM\WORK\BIOSINT.DAT 88,426 7-09-90 12:26p C:\TASM\WORK\COMMAND.DAT 227,607 8-20-91 7:45p C:\TASM\WORK\DISKS.DAT 50,715 8-02-90 7:51p D:\TASM\WORK\DISKS.DAT 50,715 8-02-90 7:51p D:\TASM\WORK\DOSINT.DAT 161,454 1-22-91 8:34a D:\TASM\WORK\DOSSYS.DAT 116,680 10-13-90 2:26p
