Mark,

If you are only bothered with compressing single files and not putting them in an archive then you could try the zlib OCX control.

http://www.info-zip.org/pub/infozip/zlib/

Its ZIP compatible and is real easy to use from VFP.

with ThisForm
   .oleCompress.InputFile  = "c:\test.txt"
   .oleCompress.OutputFile = "c:\test.cmp"
   .oleCompress.Level      = 9
	
   *!* Perform the compression.
   .oleCompress.Compress()
endwith
