Question: I can't find the creation date in the properties. Is there a way to know? I tried arranging the files by modification as to know which were created first but I don't know if it is in ascending or descending order.

Answer: 
I don't think creation date is stored. There is a modification date associated with any file, which you can see by running `ls -l` in terminal (`Ctrl+Alt+T` should open it). But if you modify any file inside the directory, I believe this modification date is touched.

EDIT: Here's a more precise answer: <https://stackoverflow.com/questions/14842195/how-to-get-file-creation-date-time-in-bash-debian>. Seems like you can see creation date, using debugfs. But only for ext4 fs.
You may try installing KDE Dolphin File Manager: `sudo apt install dolphin`
, and tick/enable "Created" column.
