CopyConfusion (Renames Copy Files) 1.0
Renames copy files that are in the old format, new format, or both. The old one is like "Copy of File.ext" and the new one is like "File – Copy.ext". In both cases, a number in parentheses would be added if you make multiple copies of a file.

In addition, it allows for first copy files to have a number in parentheses and to use two-digit numbers when there are at least 10 copies of a file. Using these options would result in better sorting in File or Windows Explorer.

CopyConfusion requires Windows 98 or Windows NT 4.0 or later and does not contain any adware or spyware. (Trial period: 15 days. One-time fee: $4.99. Released on 10-April-2016.)
