Examples:
Example 1:
Add all files and subfolders of C:\FREEDOS to C:\archive.arj
fdnpkg install arj (OR: start fdimples and install arj from CD)
arj ac C:\archive.arj C:\FREEDOS\*.* -r
Example 2:
List contents of archive C:\archive.arj and send the list to
C:\archive.txt
arj l archive.arj > C:\archive.txt
Example 3:
Restore C:\archive.arj to C:\test\ :
arj x C:\archive.arj C:\test\ *.*
Example 4:
Backup all files on OS partition C: to D:\backup_c.arj (without
MBR):
fdnpkg install arj (OR: start fdimples and install arj from CD)
copy C:\FREEDOS\BIN\arj.exe D:\ OR: A: if you have a boot diskette
(you may need arj for restore later)
arj ac D:\backup_c.arj C:\*.* -r
Restoring all files back from D: (partition C must still be OK!)
You need a bootable diskette or live CD etc, (if you can still boot
from C: you can also use it), boot from it and goto D:
D:\arj x D:\backup_c.arj C:\ *.* (you are asked for creating a
directory, enter "a" for "all".
