Finding files

Locate any file by name or type, quickly

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.

Speed

Fast to open

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

The file table read in one pass, with rows appearing as they are found and a Stop button
Scanning

Whole-drive scan in one pass

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.

Accuracy

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.

Privacy

Your file data stays on your machine

File names, file contents and scan results are not sent anywhere, and there is no tracking.

A copy used for personal use makes no connection to us; an organization’s copy contacts the license server to activate and re-check its license and, while it is being evaluated, once a week. The privacy notice lists what is sent.

FAQ

Frequently asked questions

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.
How does it read a whole drive so quickly?
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 does not prompt. 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 intended to stop one unresponsive share from holding 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. File names, file contents and scan results are not sent anywhere, and there is no tracking. A copy used for personal use makes no connection to us. An organization’s copy contacts the license server to activate its license and for a monthly license check, and while it is being evaluated it also sends a weekly check-in. Those requests carry the license key (once there is one), a machine identifier, the computer name (license requests only), the application version and the evaluation dates, and nothing about your files. The privacy notice has the details.
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 installer is designed to restore the previous version automatically.
