Change return value of FileGetSize() on failure.

[Anonymous]

Please change the return value of FileGetSize() to -1 when failure occurs. This would make more sense as it is also the way that DirGetSize() works.

Consider the following code.

If Not FileGetSize($sFile) Then FileDelete($sFile)

This code will delete a file if its size is 0. Unfortunately, it would also delete the file if FileGetSize() failed for any reason. Changing the failure return value to -1 would avoid this problem since Not(-1) = False.

Uh, no. If you need to know if an error occurred then check @error. That's why functions set it.
