Compressing\Zipping Large Files

[tekdudedude]

Hello,

On files less than 50gb PKZip (version 8 & 9) and 7zip work fine for me. Over 50gb if fails saying not enough system resources. After checking I have confirmed that I have ample disk space and it is defragmented. MS compress blows up somewhere over 40gb per file too for me.

Can you recommend a file compression tool that I can use in a batch file that will compress files larger than 50gb?

I need to compress them because they are copied to another system (net bandwidth, speed etc.).

Thanks,

TD

ALZip says their compression scheme will work with any size/number of files. Be aware that it is a proprietary method and only ALZip programs can unzip it AFAIK.

It is quite possible u simply ran out of available memory during the compression process. Have you tried using alternate compression methods like WinRAR or TAR? Otherwise try compressing your files in smaller batches.

If the zip program used to compress the files is using 32-bit internal offset values (Zip32 specs) then the largest file that can be compressed is 4GB. I don't know that the 64-bit limitations are.
