Dos command to compress a large text file using zip or rar

my batch file has the commands:

set Filename=DATABASE_%date:~-4%%date:~-7,2%%date:~-10,2%.sql
c:\mysql\bin\mysqldump -u root mydb > %Filename%

This creates a backup file each day. The files are over 100mb so disk space is disappearing fast. When I zip the file it shrinks to only several mb. This is more manageable, so how do I automate winzip or winrar to archive and delete the file?

Thanks

Frankly, I use the free InfoZip "zip.exe" command - that would simply be:

zip -9 %filename%.zip %filename%

based on your example

If you have the registered version of WinZip Pro, it does support a command-line interface that is quite powerful.  You can download it from http://www.winzip.com/prodpagecl.htm, and the command line would probably be something like:

set Filename=DATABASE_%date:~-4%%date:~-7,2%%date:~-10,2%.sql
c:\mysql\bin\mysqldump -u root mydb > %Filename%
wzzip.exe -a DATABASE_%date:~-4%%date:~-7,2%%date:~-10,2%.zip %Filename%

Hi!

You can use PKware Utility for ms-dos.
(Both PKZIP and PKUNZIP)

{
PKZIP -& -rp A:DIR
PKUNZIP -d A:DIR
}

PKZIP is NOT free - that's why I recommend infozip, which is. Also, the 16 bit pkzip program has limitations and the newer one from PKWare is a time limited trial.

I'm very familiar with pkzip 2.04g.  It is NOT free - it IS shareware - click on the manual - at the top it CLEARLY states it is shareware.  In addition, it's 16 bit (no consumer OS was 32 bit when PKZIP was released).

I agree with that. I have even doubts if the link is completely legal.
It includes for example Turbo Pascal 5.5. But this is not freeware! It is free of charge, but still copyrighted. It is very clearly stated that "These files may not be made available via the Internet or any hard copy media" (see http://bdn.borland.com/article/20803)

You could try drvspace in your config.sys
Pkzip might also work.
You could also cut the space it takes up in half by making it only backup every other day.
