Error Codes for File operations

[GEOSoft]

Right now the returned value for a failure contains nothing of any meaningful value.
It would be nice if We could get an actual error returned using GetLastError()

Example
32 = "File In Use"

I forgot to mention that I am explicitly refering to FileCopy() and FileMove() here.

Internal implementation of these functions may or may not use APIs you suspect. Also implementation may change depending on whatever reason.
What I'm saying is that last error of GetLastError is not certain to be generated.
