 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).

+The files are archived and can me downloaded [here](./assets/files.tar.gz).
 I advise you to keep a copy of the archive so you can run your scripts multiple times until you achieve a desirable outcome.

 Have a look at this [library](https://github.com/TNThieding/exif) and figure out how to use it.
 It might be handy to install `imagemagick` via `sudo apt install imagemagick`.
 This gives you the ability to inspect metadata on the Linux command line via `identify -verbose BJtpWU7n7WCeOL2B84Vz.jpg`.
+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.
