Hi,
Great, but you will have to understand QDOS file headers and te attached QDOS files on emulated QLs, which ad the QDOS header to the start of each file.
But emulators alike Q-emulator (registered) can remove the QDOS file header and make the file QDOS compatable.
I general, I extract zip or other archived files up files into a QDOS/SSQ/E environment.
If there is a QDOS file header stuck on the front of the file, I use Q-Emulator or SMSQmulator to copy the files from a native file directory to a QDOS directory, which removed the QDOS file header and is not QL compatable.
There are now new UNZIP programs to do all this, but I do it the old and easy way...
