Changing only capitalization of filename doesn't work

It seems to be a recent Windows 'upgrade' that any simple change of a filename's case does not get applied.
I found the only work around is to give it another name then reattempt the original case change.
I don't know how to make a 2 pass rule set to get around it yet.

Re: Changing only capitalization of filename doesn't work

Hi and welcome.

Please post that names (old and new) you had trouble with.

Also mention your OS version and build, and the bitness.

Which ReNamer version did you have used?

Re: Changing only capitalization of filename doesn't work

Sorry, Windows 10 Education.  version 22h2 OSbuild 19045.3693 Experience Feature pack 1000.19053.1000.0 64-bit OS and processor. Intel core.  with SSD drive and seems to be PnP driver.
Example old file name: P1060328.JPG. New file name should have been all lower case:  p1060328.jpg.  I checked the include extension box.  File name didn't change although the preview / validation step showed what it should have been correctly. I had about 18k files to change, although it didn't make a difference when trying with only 50.
I used Renamer 7.5 (date 20230325:1648).
I checked on google, some other people have had similar issues even back in 2021 - not necessarily on Renamer, but with manual amending in windows explorer.  Apparently some people don't have the problem, and some do.
It does seem to be a windows bug, not a renamer bug.

Re: Changing only capitalization of filename doesn't work

It sounds like operating system and/or file system limitations.

For example, FAT32 file system (most commonly used on removable drives) is not case sensitive. It literally ignores case changes. The only way to make a case change in FAT32 is by making a more significant change, like adding and then removing a letter.

What file system are you working with?

Re: Changing only capitalization of filename doesn't work

File system is NTFS.  And I'm changing names on the C drive, which is the default boot drive and not an external / removeable drive.
I would think by now most automatic renaming programs would have an automatic temporary rename work-around option to help with this rather painful bug (aka MS feature).
