if you want to remove the 001, 002 from the pre-installed rom names, here is a solution:

• Download powertoys, specifically power rename.
• within the folder you want to rename, right click and select power rename
• add the following into the find field:

^(?:\d*)\s+(.*)$

• check - use regular expressions
• add the following into the replace field:

$1 

• select “filename only” on the apply to field.
• check the results on the right pane
• click apply :)

This is at your own risk. Keep an eye on the preview on the right to make sure you’re not renaming something you don’t want too.
