  Windows or Microsoft.

INSTALL

1. Download Duplicate-Inspector-Setup.exe from the official
   page at https://supportamk.com/windows/duplicate-inspector/.
2. Confirm that the installer is 22,555,397 bytes.
3. Verify this SHA-256 value:
   62D3AD394B0C2F26CD791F3A14E3072490EEA6998BCC3E26E0F0201FE3BAB738
4. Open the installer and review the licence and data-safety notice.
5. Follow the Inno Setup screens. The normal per-user installation does not
   require administrator access.
6. Start Duplicate Inspector, read the first-run safety notice, select a
   folder, and review the scan settings before scanning.

UNSIGNED INSTALLER WARNING

The installer is not Authenticode signed. Windows may display "Unknown
publisher" or a SmartScreen warning. Download only from the official page and
verify the checksum. A Microsoft Defender custom scan reported no threats on
1 August 2026, but that one result is not a guarantee.

SAFE USE

- Exact matches use file-content hashes. Same-name matches may have different
  contents.
- Review every preview, path, and match reason before selecting a file.
- Cleanup requests a move to the Windows Recycle Bin. If the recycle operation
  fails, the source file is left in place.
- The Recycle Bin is not a backup. Keep a separate current backup of important
  files.
- The app cannot guarantee that every duplicate will be found or that every
  selected file is unnecessary.

INTERNET AND LOCAL FILES

Installation, scanning, review, and cleanup work without internet access. The
optional Donate action opens supportamk.com in the default browser.

Video poster frames are requested from Windows media handlers. This release
does not contain FFmpeg, imageio-ffmpeg, an FFmpeg executable, or FFmpeg
libraries. Local preferences, cached video thumbnails, and crash logs may
remain under the current user's local application-data folders after
uninstalling.
