SnapSentry watches the Windows Screenshots folder and handles new screenshots as they are saved. It can copy the image, delete the saved file after a delay, or let you choose from a notification.
- Delete now removes the file without changing the clipboard.
- Copy image and delete copies the image, then removes the file.
- Keep leaves the screenshot alone.
- If nothing is selected, the configured automatic action runs after the delay.
Deletion is off by default, since it is the irreversible part; turn on Delete the saved screenshot to opt in. When it is on, deletion sends the file to the Recycle Bin so an accidental delete is recoverable, unless you turn that off for a permanent delete.
- Image copies a bitmap that remains pasteable after the file is deleted.
- File copies the file for pasting into File Explorer. Deletion is disabled.
- Path copies the location as text. Deletion is disabled. You can choose how the path is written: plain, quoted, as a clickable file link, or as a Markdown image reference.
- None leaves the clipboard unchanged.
SnapSentry can rename each new screenshot using the title of the window that was
in front when it was taken, so files read like 2026-08-01 17-16-52 Preview.png
instead of Screenshot (12).png. This is optional and off by default.
Snipping Tool must be set to save screenshots automatically. The default folder
is Pictures\Screenshots. If Snipping Tool saves to any other directory, set Folder
override to that location.
While the action popup is turned on, SnapSentry registers itself with Windows so its notification buttons work. If the notification can't be shown, SnapSentry falls back to a standard dialog; but if you have turned its notifications off, it stays quiet instead, still copying to the clipboard but showing no dialog and never auto deleting. Turning the popup off, or disabling the mod, removes that registration again, so it leaves nothing behind.
SnapSentry treats any supported image written into the watched folder within the last few seconds as a new screenshot. Files that were already there, and copies of older images dragged in by hand or synced from another device, are left alone. A brand new file saved or downloaded straight into the folder cannot be told apart from a capture, so avoid pointing the folder override at a place where downloads land. It cannot remove copies already retained by clipboard history, cloud sync, backups, or other applications. Deleting a file is not secure erasure, especially on an SSD. When the Recycle Bin option is on, a deleted screenshot stays recoverable there until the bin is emptied.
Avoid a cloud-synced screenshot folder when quick deletion matters. A sync client may upload or retain the image before the local file is removed.
