Thanks StainlessS for this compilation,,,
Personally I was only concerned about getting corrupted files without any error message, so I pretty much switched to Teracopy or the Total Commander internal copy routine.
For Teracopy I should mention that I still use the older version 2.3. Newer versions caused some problems for me, and they do not work under XP. Even version 2.3 has an issue with 7-zip under XP (but not under Win7 64bit using the same 7-zip version).
