Ok, i think i understand you now: you don't whant to work with ntsf compressed folder, you whant the 'zip folder'.

hmm, i don't think the 'zip folder' is a folder at all. i think the drag-drop you were discribing earlier is a nice feuture from the explorer where in the background the zip.dll is beeing called to ADD a file to the zip file.


>Yes, that is an NTFS compressed folder. No problem there. It's the zipped "folders" that it can't copy to.

>>>These are 2 very different animals. Try opening a folder (or on your desktop) right-clicking and choosing New and then at the bottom you should see "Compressed (zipped) folder". The problem seems to be that only the GUI knows its not really a folder, but just a special file type and deals with it accordingly. The COPY commands, etc., don't know what to do with it.
