RE: KV, I definitely removed the numbers or put them at the end of the file name.
Made txt file of the whole folder (all of my files are in just one folder), simplified the path names by replacing and then uploaded the txt file to ChatGPT. It told me what I had doubles in. Simple as that. My eyes are not so good so this ChatGPT will be a helpful tool in some cases.
Here for Windows:
Bulk Rename Utility
The software above can do this and works great:
Move/Copy (6)
Move a section of text to a different place.
This section allows you to move or copy a fixed number of characters form one part of the string (start or end) to another (start, end or position). You could do this with Regular Expressions, but this gives you an alternative. So for example, if all your filenames end with a unique 6-digit sequence code, and you'd rather have this at the start of the filename, then this is the simplest way to achieve it. You can also specify a separator in the field Sep.
