Feature request: regex replace in file names

[HenkelKroos]

I had to check for a large number of PDF files: is there a sidecar XML file for every PDF file (same name - different extension)?
I think this (and other comparisons on files with different file names) could be a great job for Beyond Compare when a regex replace rule can be applied to the files in folder compare. The regex replace creates a virtual filename for every real filename and the virtual file names will be compared.

Hello,

BC4 Pro does support an Alignment Override feature. This wouldn't perform this type of comparison in a single step, but can be done in a couple of steps.

First, if you are running Std edition, you can trial Pro following this guide:

This will unlock Alignment Overrides in the Folder Compare's Session menu -> Session Settings, Misc tab.
Create a new rule to align *.xml = *.pdf
this will align the xml variant on the left, with the pdf on the right.

If you compare a folder against itself, then look at the left side for Orphans that are .xml (with no aligned .pdf), is this a list of the files you are looking for?
