SJ version 1.01
Split & Join File System
Created in May-28-1993 by
ACID 0f -SkAnDaL!-
INTRODUCTION
Thank you for using this cool utility. I hope it'll help you.
I created SJ because I was very bore to backup my hard disk with
the backup and restore DOS commands.
Now I create an archive file with Arj, Pkzip or other and then
I split this ( usually a very big file ) in little files so that
can put them on the disks.
Also you can find problems with big files on your hard disk
( for example sound or movie files ). Well, this is the right
moment for using SJ.
You must assume the entire risk of using the program.
I wrote it because all write it, not because I believe in it really.
HOW TO INSTALL SJ
1) Copy SJ.EXE in your utilities dir.
If your haven't got it create one ( for example in
this way MD \UTIL
2) Remember to check in your autoexec.bat file if this
directory is in the PATH. If not U must add the util
name in the PATH line. Now you can run SJ whatever
directory you are in.
3) Don't erase the sj101.exe file. If your friends want
SJ you must give them this file.
HOW TO USE SJ
Is very simple to use it. I'll teach you with an example.
I must backup the c:\WORK directory. Its size is 10 Mbyte.
Before to use SJ I must create a single file so I'll run the ARJ.
c:\>arj a -r backup c:\work
This command will create the backup.arj file, an archive with all
the contents of the WORK directory and sub-directory.
Now I've got a file .arj 6 Mbyte long and must put it on mini disks.
I'll use some formatted 3 1\2 high density disks.
To put the backup file on disks I must break the big file in 1.4 Mbyte
files long.
So I type SJ S 1400 c:\backup.arj c:\backup
SJ will create 4 files 1.4 Mbyte long and 1 file 400 Kbyte long.
backup.00 backup.01 backup.02 backup.03 backup.04
Now I can put them on the disks ( one for disk, eheh )
When I have done it can erase all the files on my hard disk in this way:
c:\>del backup.*
When I'll want to restore the WORK dir I'll copy the contents of my
mini disks on the hard disk.
Now I use the join option in this way:
SJ J c:\backup c:\backup.arj
SJ'll create the .arj file and I can extract its contents with:
c:\>arj x c:\backup.arj
ADVICE
This program is FREE so you can spread it around the world.
