Do you mena the files are already on NT, or are they on Linux and you want to compress then download to NT?
On Linux, gzip and bzip2 have params to change the amt of compression, more compression == longer time to compress.
Text (usually) compresses well, binaries not so much...
Need more detail, but HTH

edit: mena -> mean
darned typos ...

Files are uploaded into NT machine(Act as FTP site) from our client. I have to download those files from that machine. This is should be an automated process. Already I got your suggestions for my download process(Cron Jobs of FTP Download - Thread name). I tried to apply shell scripts of download those directly using MGET command. But it failed due to our internet bandwidth and file size. So i have decided to compress the files first, then i will start the download process through my scripts in linux machine. Download Process to be held on Linux Machine. Compress Process to be held on Windows NT machine.

Hope this information will useful for you.

Cheers,

Moorthy.GS

I'm no MS expert, and to be honest, I'm surprised NT can handle 220GB of address space. Separate drive names?
However, the 'Linuxy' soln would be to install Cygwin toolset on the NT and then use gzip or bzip2 as mentioned. iirc, at the highest levels of compression, bzip2 is more efficient, but check that first.
Alternately, winzip files can be read by gzip (usually). Try a test file.

Edit: continued ... here's a radical idea, how about rsync? It does compression on the fly, although that may only be during txfr ie you may still end up with uncompressed files on the final tgt box.

Reason for compress is atlease we can reduce the file size for better download. we have only 1 MBps of internet speed.

Cheers,
