Total Commander

Hello. Can add the option to rename files using template like:

• name length
  what characters
  case sensitive

Would be cool.

Currently only random numbers are supported, from [R1] with 1 digit to [R9] with 9 digits. It's guaranteed that no two are the same, so you can use it to rename files without overlap. Example:
image[R5]
would result in names like this
image23956
image55465
