- Thank you for purchasing ARC. To show our appreciation, we've added a few
- other utilities you may like to this disk. Here's what the different files
- on this disk are:
-
- ARC.EXE This file is the ARC file archive utility, which you'll need
- to unpack everything else.
-
- PROGRAMS.ARC This is an archive containing several utilities we've written
- that we think you may like.
-
- DOCUMENT.ARC This is an archive containing the documentation for ARC,
- MARC, and ARCE, and a short one-page description of ARC.
- This archive also contains the documentation for the LF
- utility (q.v.).
-
- SOURCES.ARC This is an archive containing the sources for all of the
- programs on this disk. Most are written in Computer
- Innovations C86 using our MACRO preprocessor, and some are
- written in IBM MASM 8088 assembler.
-
- ABOUT.SEA A very brief history of System Enhancement Associates.
-
- READ.ME This file, of course.
-
-
- The PROGRAMS archive contains the following utilities:
-
- ARC51.COM This, when run, unpacks itself into the ARC program and
- documentation. This gives you an easy way to share ARC with
- your friends.
-
- ARCE.COM This is a fast archive extraction program. It functions the
- same as the ARC E command.
-
- ASCII.EXE This searches through a file, finding and displaying any
- printable text. It can be used on any file, including
- programs, database files, and worksheets.
-
- CHMOD.COM This is used to selectively set and reset file attributes,
- such as ReadOnly, Hidden, and System.
-
- LF.EXE This is our file manipulation utility, and is very useful for
- managing large numbers of files. See the file LF.DOC in the
- DOCUMENT archive for more details.
-
- MARC.EXE This is used to merge archives without unpacking and
- repacking their contents. See the ARC manual for more
- details.
-
- OKI.EXE This is handy if you happen to have an Okidata printer.
-
- PARBOOT.COM This alters your system slightly so that a parity check
- causes a system boot, instead of a system lockup.
-
- SCROLOCK.COM This makes your "Scroll Lock" key do what its name implies;
- that is, stop the screen from scrolling.
-
- SOFTBELL.COM This changes the tone which is made when a "control G" is
- printed. The usual effect is to mute your bell, turning it
- into a softer, less annoying tone. This is dependent on
- processor speed, and will work somewhat differently on an AT.
-
- TASK.COM This is used to insert "yes or no" questions in a batch file,
- where a time limit is placed on how long to wait for an
- answer. Run it with no arguments for details.
-
- TDIR.EXE This produces a short, organized listing of the files in your
- current directory, or in another directory. Use it as you
- would the MS-DOS "dir" command.
-
- UNBACKED.EXE This finds all files which are not backed up in your current
- directory and all of its subdirectories.
-
- UNDEL.EXE This is used to "undelete" a file which was accidentally
- deleted.
-
-
- Most of these programs give a brief description of how they work when you
- run them with no arguments. For example, if you wish to know how to use
- UNDEL, you should type:
-
- undel
-
- that is, the word "undel" with nothing after it, at the DOS prompt.
-
-
- Not all of these programs are user supported software. Particularly, LF
- and UNDEL have never been released as such. You can give ARC, MARC, and
- ARCE to anyone you like, but please don't pass around the others.
-
-
-
- A word about UNDEL:
-
- The MS-DOS operating system isn't designed to allow for "undeleting" a
- file. In theory, once a file is deleted it is gone forever.
-
- However, it is possible, sometimes, to reconstruct where a file was
- located, and to recreate it. This is inherently an iffy proposition.
-
- You have the best chance of undeleting a file if it has been recently
- copied or edited, and if NOTHING has been done to the disk since the file
- was deleted.
-
- Your best chance of recovering a file is, of course, to not delete it in
- the first place. But sometimes accidents happen.
-
- Your second best chance of recovering a file is to:
-
- 1) DO NOT delete, move, copy, or create ANY files on the disk after the
- accidental deletion if at all possible.
-
- 2) If you have a tape streamer or other "image" backup, then take a backup
- before doing anything else. This will give you the ability to retry the
- undelete endlessly.
-
- 3) If you don't have a tape streamer, take a backup anyway. It can't hurt.
-
- 4) Use UNDEL to undelete the file.
-
- 5) Examine the file. If it isn't right, delete it and try again, this time
- using the "/a" (ask) option.
-
- 6) If UNDEL can't find all of your file, you may want to try the "/p"
- (partial is okay) option.
-
- 7) If none of the above works, then you are out of luck. Your chances of
- ever recovering your data are slim indeed.
