Hello Claude!
This is happening because cm_Switch83Names is on, at least in my case. The directory is actually renamed but the display doesn't show it.

I just tried with your dir name - here it behaves exactly the same in TC7pb3 and TC6.56 with or without cm_Switch83Names enabled on Fat32 and on NTFS partitions.
If cm_Switch83Names is enabled "Rc1" and "RC1" are both displayed as "Rc1" - whereas "rC1" and "rc1" are displayed as "rc1". When cm_Switch83Names is disabled everything is displayed as written.
