How does it work?

After this function gets called, it'll generate a list of files based on the following conditions:

• If extensions are specified, it'll only attempt to add files ending in one of these extensions to the list of files to be processed

• If extensions are not specified, it'll add all the files to the list.

Then, NameNumerizer attempts to append the numbers to the start of the file name in this format:

##. FileName.ext

where:

• ##: the file number that is padded left to the number of digits for the last file, for example, it'll be 001 if the list contains 100 < n < 1000 files.

• FileName: The usual file name

• .ext: The usual file extension

NameNumerizer repeats the operation for all the files to be processed.
