File Compression / Decompression

Can anyone recommend any components that I can use to uncompress patch files that are automatically downloaded via ftp? I thought about just distributing PKUNZIP with the application, and just shell it?

When I made an auto-updater/patcher, I just decided to use the unzip dlls, they work fine and it's good enough for an updater/patcher.

Any chance of a link to the DLLs?

I think they're on www.cdrom.com(but that's just the dlls), but I am very sure you can find at least three good dlls with delphi headers and sample code included on torry's delphi pages. Here, this is the one I used http://www.torry.net/vcl/compress/std/zunz.zip

But there are others out there, if you just want the dlls themselves, do a search for Info-zip dlls on google, although they may just be in that file I just mentioned, not sure..

Thanks

I ended up using ZipMaster, it contains the zip and unzip DLL and a VCL wrapper. Very simple to use! Just need to mod my auto patch now!
