Getting startedHow do I install and activate DiskHalo?
When downloads are available, get the Mac or Windows installer from the download page; no account or email is needed. Follow the operating system’s installation prompts, open DiskHalo, enter your purchase email, then type the 6-digit code we email to that address.
Activation needs an internet connection. After activation, a signed licence is kept on your computer, so disk analysis works offline. To set up another computer later, sign in again with the same purchase email.
Go to the download pageGetting startedWhich folder should I scan first?
Start with a folder you know, such as Downloads or a project folder. Select it in DiskHalo and let the scan finish. The first scan only reads your files. It doesn’t delete anything.
Use Storage Orbit, the treemap or a list to find the biggest folders. Drill down until you understand what is taking up the space. A large file isn’t always one you should remove.
Scanning & cleanupWhy are some files missing from my scan?
Your operating system may restrict access to protected folders, another user’s files, or online-only files that haven’t been downloaded to this computer. A disconnected external drive or unavailable network location can also make a scan incomplete.
Check that the location is connected and readable, and review any access warnings. On macOS, review the app’s permissions in System Settings. Only grant access to the places you want to analyse, and don’t turn off your system’s own protections.
Scanning & cleanupWhat should I check before removing files?
Inspect the file’s name, location, size and category. Preview anything you’re unsure about, close any apps that may be using it, and keep a backup of important work.
See it before you remove it. Nothing is deleted without your confirmation. Cleanup deletions are permanent. Deep Cleanup, Large File, Duplicate, app-leftover and Uninstaller deletions are the cleanup actions this applies to. Back up anything important and check each item first.
Read the confirmation carefully. Cancel if you don’t recognise a file or aren’t sure what it’s for.
Scanning & cleanupHow do I clean up duplicates?
Duplicate detection compares file contents rather than relying only on matching names. Review each group and keep the copy in the place you want it.
DiskHalo is designed to keep at least one copy in a duplicate group. Duplicate deletions are permanent, so check links, project references and backups before removing copies that other applications may expect to find.
Scanning & cleanupWhy does the free-space number differ from the scan?
A folder scan and your operating system’s capacity display can measure different things. Snapshots, reserved space, compressed files, shared blocks and files you cannot access can affect the total.
After a cleanup, the system may take time to update its free-space figure. Deep Cleanup, Large File, Duplicate, app-leftover and Uninstaller deletions are permanent and skip the Trash or Recycle Bin. Files you moved to the Trash or Recycle Bin yourself still use storage until it is emptied.
Licence & billingMy sign-in code hasn’t arrived. What can I do?
Check spam or junk and search for DiskHalo in the inbox used at checkout. Codes are only sent to an email address with an active purchase, so use the address that received the receipt email from our checkout provider.
Each code expires after 10 minutes and works once. You can ask for a new code after 30 seconds; requesting a new one replaces the previous code. After several requests, wait 15 minutes before trying again.
How to sign inLicence & billingWhy is licence activation not working?
Check that you entered the purchase email and the latest 6-digit code, and that your computer has an internet connection and the correct date and time. After five incorrect codes, request a new one.
Your licence covers up to 3 personal devices. If every device is in use, deactivate DiskHalo on an old computer before adding another. A refunded or revoked purchase can’t activate a device.
Licence & billingIs DiskHalo a subscription?
DiskHalo is a one-time purchase for Mac and Windows, for up to 3 personal devices. There is a 30-day money-back guarantee. The next major version may be a paid upgrade.
Licence & billingWhere can I find receipts and request refunds?
Check the receipt that our checkout provider sent to your checkout email. Its link can help with payment questions and refunds, or you can email DiskHalo support.
DiskHalo purchases include a 30-day money-back guarantee, in addition to your legal rights.
Read the refund policyTroubleshootingA scan is slow or appears stuck. What should I try?
Large folders, many small files, slow external disks and network storage can take longer to scan. Check whether the progress or file count is still changing and whether the source is connected.
If you need to stop, use the app’s cancel control. Try scanning a smaller local folder to narrow down the issue. Avoid unplugging a drive while files are being changed.
TroubleshootingWhat information helps explain a problem?
Note the DiskHalo version, your operating-system version, the tool you were using, and the steps that led to the problem. Record the exact error message and whether it happens with a small test folder.
If you choose to share a screenshot or report, remove personal file names, paths, account details and sign-in codes first. Do not share private documents or a full disk inventory.
