I have a folder 'data' full of folders which are named like this:
E:\data\foldername1\
E:\data\foldername2\
E:\data\foldername3\
...
E:\data\foldername100\
E:\data\foldername11\
...
I would like to rename the folders with one digit (foldername1- foldername9) with two digits, like that:
E:\data\foldername01\
E:\data\foldername02\
...
As I have lots of those 'data' folders I would like to automate it. I tried without success so far... Could anyone please help me?

If you rename E:\data\foldername1\ to E:\data\foldername10\, then what about the existing E:\data\foldername10\?

You can use dir, sscanf, sprintf and movefile.
Use dir to get the list of the folders.
Use scanf to get the number of the folder:
sscanf('folder39','folder%d')
ans =
39
Use sprintf to write the new folder name
sprintf('foldername%04d',15)
ans =
foldername0015
Use movefile to rename your folder.

Thank you! Just running into a problem here:
NewName = sprintf(thisDirName '%02d', EndNumber)
Just because my folder names are actually all different to one another I cannot use
sprintf('foldername%04d',15)
Any suggestion?

Figured smth out:
NewName = sprintf('%s%02d',thisDirName(1:end-1), EndNumber2)
working now! Thanks a lot for the help
