'RLE'

If we have a text file with 'abcdeeee' (8 bytes) we could shorten the repeating four byte run 'eeee' with (ee followed by a byte to specify the total run length of e). This will shorten the output of the file to abcdee (7 bytes). The last byte being the ascii representation of the run length of (e).
