Hello, According to TZipMaster help: property SpanOptions: SpanOpts; spCompatName If True then uses names of the form name.zip + name.z01 ... That's just what I need, but it simply doesn't work as expected. When I set spCompatName and try to compress something to the diskette I still have the name.zip written on every one of it. I tried it in my own project and also tried to modify the Demo6 example - same results. spNoVolumeName works fine. I think that's a bug, maybe somebody encountered such a behaviour? Thanks in advance for your help, it's very important to me.
