I keep confidential data (docs, spreadsheets, images, etc) on USB sticks or discs. I plug/insert them to access the data when I need, and put them back in a drawer when I'm done.
- Does Ubuntu store this data (in cache, or somewhere else)
- For how long?
- How to delete this from Ubuntu?
- How to stop Ubuntu storing this data in the first place?
p.s.: I'm already aware of the cache directory to store image thumbnails, but I'm asking now in terms of the entire file being stored. Thanks.
