File extension case

[chirsmVis]

Hey folks,

Can the Bulk Rename Utility be used to mass-modify the case of file extensions across multiple folders?
In a perfect situation I would be able to change ALL file extensions in a directory to lower-case.

I'm using a syncing tool called 'Syncthing' and it does not like differences in file extension case, which is causing me some issues trying to combine large sets of data.

I appreciate any info, tried to search on this but it was too common a set of phrases to get anywhere.


Thanks much!

Inside Filters(12) to only put checkmarks inside for "Files" and "Subfolders".
Then Extensions(11) can be set to "Lower".

Can also google-search common phrase like... site:www.bulkrenameutility.co.uk case extension
