Your disk has a past.

A local file explorer that remembers what changed, who touched it, and what is taking space. History stays on your PC.

Five questions the explorer answers

History

What changed on this disk?

Activity is a timeline of creates, writes, renames, and deletes — not a reconstructed folder from last Tuesday.

Attribution

Who touched this file?

Process names sit next to events so you can see which app wrote the path, not only that the path exists.

Space

What is taking room?

Storage walks current on-disk size: categories, extensions, age, and a treemap. It is not a cloud dashboard.

Privacy

Does history leave this PC?

No. The service records locally. Polar only takes payment. diskpast.com issues the key, not your file events.

License

How many PCs?

One-time purchase, one hashed Windows PC. Deactivate in Settings if you move the seat.

Privacy

Disk history stays on your PC.

Polar takes payment. diskpast.com shows your license key. File events never go to either.
