It has been pointed out recently that RW_Tools was reporting some .ap files as being zero byte files when this check was made on the users system. It turns out that the routine used in Visual Basic to find zero byte files could not read filelengths of over 2 gigabytes and thus responded with 'Filelength = 0'
I have amended the program to ignore '.ap' files in this check, so I would urge anyone who uses RW_Tools to check for zero byte files to update to v6.0.78 as soon as possible.
