OBThis folder is empty on purpose, but must be populated by the trainer before the course for participants to use. Below is a list of what files should be included for answering questions in Exercise 3 and to give the richest learning experience.

It is recommended that the exercise is trialled and answers are recorded BEFORE the course is run.

The DROID test set should include the following files:

-  some unique file types (preferably research data), such as: .mat or .nii
- .doc and .docx files
- one or more .zip files that contain a variety of other files
- multiple versions of PDF (minimum of 2, but 3 or more is better)
- image files such as .tiff, .jpg and .png - different versions of them is also good
- text file with the .txt extension and another text file with no extension at all
- sound files such as .wav, .mp3, .aiff
- .epub or .mobi files
- .xlsx and .csv files
- .xml file
- include a file with the incorrect extension (for example a TIFF file with a .jpg extension) 
- include some unidentified file types
- include some files with no extension at all
