Hello All ,
I am using Rl ARM Library for file system .
When I use frename() function for renaming existing file there is one issue ,
for e.g
Old file name = Welcome.txt
and renaming to
New file name = minor.txt
then this frename() function rename file name Welcome.txt to MINOR.txt
but new file name should be in small case letter and now it is renamed in capital letter .
and this issue happens only when file name contains all letter in small case .
Please someone provide a solution for this issue .

If you mix upper and lower case, then the file system stores it exactly. If you have all lower-case or all upper case and within the 8.3 length, then the file name is stored in original MS-DOS format, i.e. all upper-case.
