How can i rename only extensions as lowercase?

[Astoria]

Found, that is the limitation indeed (https://www.ghisler.ch/board/viewtopic.php?p=388494&sid=3e9b1a60297a71e3733a18f02af53c1f#p388494).
There is 2-step renaming as a workaround. It's a pity TC can't do this 2 steps himself ((
Because I can't use 1-key operation to fast rename ext to lower case (

Strange, but for me works on 32-bit TC version ONLY, on Windows 10 x64
So a better workaround might be to use a 32-bit TC.

Just use "First letter uppercase" in MRT - see: https://madsenworld.dk/tcmd/MRTFirstLetterUP.png - works fine here on FAT32 and exFAT USB-drive with TC 10.52 32bit and 64bit on windows 7 and with TC 10.52 32bit on Windows 10, but not with TC 10.52 64bit on Windows 10.

What if the names contain more words to be capitalized?

Then you use "First of each word uppercase (English in Titles)" (the last option).

You can define which small words that should not be in uppercase in wincmd.ini with the parameter:
LowercaseStrings=English in Titles:a,an,the,at,by,for,in,of,on,to,from,up,and,as,but,or,nor,yet,so,vs

Are you sure this is really the right way? http://gral.y0.pl/tc/FirstofEachWordUppercase.png
I think that is still better use [L][E] on 32-bit TC.

I think that is still better use [L][E] on 32-bit TC.

Of course if you want to preserve words like POSReady and only want to make the extension lowercase, then [L][E] is the right way.

Thank you for the replies )) I'll try 32-bit TC, but it's very strange difference indeed.

Maybe ghisler(Author) will reply, is it bug or not?

PS. Sorry for my poor English.
