Claim Disk
Free for personal use — forever

Claim back your disk space in seconds.

Claim Disk reads the drive’s own file table instead of walking folders, so the whole disk appears almost instantly, sorted by size and ready to clean.

Free for personal use — every feature, no time limit, no reminders.
Free two-week trial for organizations — business, government and non-profit, then a one-off license per computer.

Finding files

Locate any file by name or type, in an instant

Claim Disk is not only for finding what has filled a drive. The same index answers a direct question just as quickly: where is that file, what type is it, and how many copies of it are there?

The type filter open, listing ten file-type categories and the extensions each covers
Ten file-type categories, each listing the extensions it covers — documents, email, images, video, audio, archives and executables among them.
By nameType any part of a file or folder name and the list narrows as you type.
By patternWildcards such as *.iso, report*.pdf or test??.log.
By locationPath patterns such as C:\Users\*.pdf or Downloads\*.zip.
By typeTen categories, or folders only, or files only, across the whole drive.

Every filter runs against the index already held in memory, so results appear without reading the disk again. The filter stays with you as you move between folders instead of resetting, and Locate in Tree jumps from any result straight to where it sits on the drive.

What it does

Everything you need to reclaim the space

Built on a single principle: present the result immediately, then allow it to be acted on without leaving the window.

Instant open

A background service keeps your drives indexed, so results are on screen when the application opens, and stay current as files change.

Whole-drive scan in seconds

With no index ready, the file table is read in one pass instead of folder by folder. Rows appear as they are found, and Stop keeps them.

Size on disk, not guesswork

Compressed and sparse files are counted at what they truly occupy, so the number matches what deleting actually gives back.

Nothing leaves your machine

No telemetry and no tracking. The only network traffic is license activation and a periodic license check.

Every kind of volume

Network drives, memory sticks, external drives, virtual drives and unlocked encrypted drives, each treated as the ordinary drive it appears as and read by the quickest route available.

Run it, or install it

One setup file. Install it with the indexing service, or choose Run only and start straight away with no administrator prompt.

Questions

Straight answers

Is it really free?
Yes — for personal and household use, with no time limit and no features held back. Organizations use it free for fourteen days, after which a license is required. Even then nothing stops working: a reminder appears every other day until a key is activated.
Why is it so much faster than other tools?
It reads the drive’s own file table in a single pass instead of asking Windows about each folder in turn, and a background service keeps an index ready between runs, so the application usually opens with the results already loaded.
Does it need administrator rights?
Only to install. With the indexing service in place, ordinary day-to-day use never prompts. The portable option runs with no administrator prompt at all.
Does it work on network drives?
Yes. Shared folders on another computer and mapped network drives are read using the standard Windows file-sharing connection, with a safeguard so that one unresponsive share cannot hold up the scan. Network locations are re-indexed on a schedule you choose, from every fifteen minutes to daily.
Does it work on encrypted volumes?
Yes. An encrypted drive that has been unlocked is treated as the ordinary local drive it appears as, including those created by TrueCrypt and VeraCrypt. Memory sticks, external drives, virtual drives and drives prepared for older versions of Windows are all handled in the same way.
Can I run it without installing?
Yes. The same setup file offers Run only, which starts the application straight away, with no administrator prompt and no changes made to Windows. If you decide to install it properly afterwards, the application will do that for you and nothing needs downloading again.
Does it send my file names anywhere?
No. There is no telemetry and no tracking. The only network traffic is license activation, a monthly license check-in, and for organizations a weekly trial check-in.
What happens when I upgrade?
An existing installation is detected and upgraded in place, keeping your license, trial status, usage type, service settings and saved index. If an upgrade fails, the previous version is restored automatically.
