How to use arj compression commands
arj a a:pp c:*.dbf General method, use arj x a:pp to extract
arj a -r -va a:pp c:*.dbf
arj x -r -va a:pp The -va parameter automatically checks the remaining capacity of drive A:,
the -r parameter automatically compresses files in subdirectories.
arj a -je a:pp c:*.dbf When extracting, just run pp.exe directly.
The -je parameter automatically generates a self-extracting file.
arj a -r -va -g? a:pp c:*.dbf Creates a password-protected file
arj x -r -va -g? a:pp You need to enter the correct password when extracting.
arj a -r -vva a:pp c:*.dbf Rings a bell to prompt when changing disks.
-jt Performs verification during compression to ensure the data is intact.
e Automatically creates subdirectories when extracting, no prompt needed
l Displays the directory of files contained in the archive.
-o:980818 Compresses all files after August 18, 1998 (including that day)
-ob:980818 Compresses all files before August 18, 1998 (not including that day)
Various prompts:
Quit abort and exit
Always always answers "Yes" to the current question (when extracting compressed files, if you need to overwrite an existing file, then you need to answer "A".
Skip gives an affirmative answer to the current question.
Yes gives an affirmative answer only to the current question
No gives a negative answer only to the current question
Global gives an affirmative answer for the current disk; after changing disks, you need to answer again.
