I don't really care what ordering system you use but thousands of files in one directory is **not** practical. I don't really care what ordering system you use but thousands of files in one directory is **not** practical.
There are four different folders with files to sort and each one is a **separate** assignment so at the end I expect **four** folders with **sorted** files (and subdirectories).

I left the file extension on purpose to make it a bit easier but in the last exercise you'll have to live without so maybe try not relying on the extension to prepare yourself.
### Music metadata
This batch is similar to the previous batch but instead of photo's it's a bunch of mp3's.
As with photo's mp3's have metadata in them do help with sorting in programs like iTunes.
There are multiple libraries out there to read and write these tags with Python3 but none come installed by default.
I can recommend [eyed3](https://eyed3.readthedocs.io/en/latest/) to parse the metadata.
Here it makes little sense to sort via date so maybe sort by `$ARTIST/$ALBUM`.
As an added bonus you could rename the mp3's by their track number instead of the cryptic string the have.
### Mixed filetypes
This one is very tricky.
It's a mix of photo's and mp3's and the extensions are missing!
You'll have to figure out how to determine the filetype before reading the metadata *or* have a deep dive into `try except` statements in Python3.
