>I have a funny problem. I need to copy a file to %temp% folder and I should check whether the source file is actually that same file. I'll check that some other way, probably using LLFF, but while trying to just compare folder names I ran into a problem. The sourcefile's name is retrieved from the file dialog ocx (of msComCtl), and its name looks like c:\users\dnedeljkovich\AppData\Local\temp\something.ext, however my app.tempPath is set from getenv("temp") or sys(2023) which both give c:\users\DNEDEL~1\AppData\Local\temp\something.ext - which is the same path, just that the latter is in dreaded old 8.3 (and yes, issuing set in cmd.exe shows that TEMP environment variable is exactly what getenv() shows).
