Hi Grigore,

The functionality must exist in the OS somewhere, but can it be accessed programmatically or not, that is the question. If the GUI can do it, it should be able to be done programmatically, I would think.

Your previous try to create the zip file with STRTOFILE failed because it's equivalent with "a text file is internally equivalent with a zip file", which is not true. A zip file has a specific header, where it contains the info about the contained files.

According to MSDN, in the system one can find these three dll's: dunzip32.dll, dzip32.dll and zipfldr.dll. These three are doing the magic. Your copy/paste operation is a call to these dlls.

However, the OS still allows me to create Compressed folders, so it means the functionality was moved to some other dlls. They are not documented in MSDN, so I can't help you further, but I strongly believe my presumptions are correct.
