Deguffer knows 137 locations. Each one is a provider: a single class that names one cache, log or leftover, the tool that writes it, and the children it recognises. Anything a provider does not recognise is left alone.
The tiers say what deleting costs you:
| Tier | Meaning |
|---|---|
| 1 | Regenerable cache: Generally safe to clean. |
| 2 | Regenerable, with cost: Clean it when you need the space. |
| 3 | User data: Clean it only once you are sure you no longer need what is in it. |
A Researched provider was written from the publisher's documentation and reports from users, not from a real installation. It keeps every safety rule, but it is never pre-selected.
For where each location is, how Deguffer cleans it and what the next use costs, see What Deguffer cleans, and what it costs you.
