hi,

I'm using the ZipMaster freeware component which turned out to be very good. Just look for it in one of the Delphi pages like Tory's or Delphi Super Page.

Also you may try another TZip component:

michaenh,

I'm not keen on using random components either but I can recommend a product my company has used for zipping/unzipping files. It's called Abbrevia (made by TurboPower, who decided to release much of their VCL as open source) and you can download it from:

http://sourceforge.net/projects/tpabbrevia/

It supports PKZIP 4, Microsoft CAB, TAR, & gzip formats.

Hope this helps!

hi Stretchwickster,

I've used Abbrevia as well and it didn't please me.
First there have been some strange "features" I could't explain, and then the compression speed was very very poor compared to TZipMaster. Even with setting "optimize speed" (or something like that) it turned out to be 3 to 4 times slower than ZipMaster when compressing many files in one folder.

I cannot recommend Abbrevia.

I use a dos version of PKZip and simply call it with CreateProcess.
