Thanks for the tip. Since teh VFPCompression started working again, and no other client had the same issue, I did not change that part. However for next time I would try using vfx.fll to see if I can build a wrapper for that one.

With 20 files you mean to iterate batches of 20 files each to add them to the same archive, or to add maximum 20 files to one archive and create multiple zip files?
