MarginDiff Scrub inspects supported file metadata and removes the categories you
select. Start with a copy and review both the findings and the cleaned result.
Cleaning is not a guarantee that every sensitive detail has been removed.
## Inspect files
1. Open MarginDiff Scrub and use **File > Add Files** (**Ctrl+O**) to select files.
2. Review the detected metadata and any warnings or manual-review findings.
3. Select a profile in the **Profile** selector. **Full Clean** is initially selected.
4. Review the profile's cleaning actions before choosing **Clean**.
The file chooser can narrow the list to Word, Excel, PowerPoint, PDF or Graphics.
Graphics includes supported JPEG and PNG files; All Supported Files includes
other supported formats. Showing a file under All Files does not make its
format supported. See [file selection](/docs/file-formats/#selecting-files-in-margindiff-scrub).
## Save and verify cleaned copies
Choose an output folder and save cleaned copies. Replacing originals requires
an additional confirmation. Cleaning options can affect visible content: for
example, removing comments, accepting revisions or removing presentation notes.
Choose actions appropriate to the documents you are sharing.
Check failures, warnings and verification results, then open the cleaned copies
in their original applications. Keep the originals until you have verified the
results. Export HTML or CSV results when you need a record of the work.
Signed or encrypted PDFs and damaged or unsupported files can prevent cleaning;
follow the reported limitation instead of treating the operation as successful.
## Profiles and preferences
Use **Profiles > Edit Profile...** to inspect the chosen actions. Personal and
company profiles can provide repeatable choices. **Manage Profiles > Bulk Edit**
lets you edit several profiles; it changes profile settings, not the files.
See [bulk profile editing](/docs/file-formats/#editing-several-margindiff-scrub-profiles).
MarginDiff Scrub remembers its window position and personal appearance preferences.
See [saved preferences](/docs/file-formats/#margindiff-scrub-preferences-and-window-position).
## Clean Outlook attachments
Enable MarginDiff Scrub's Outlook integration in **MarginDiff Scrub Settings** and restart
classic Outlook. New Outlook cannot load this native Office add-in.
Sending an email with attachments opens **MarginDiff Send**, showing the attachment
filenames and **Clean**, **Do Not Clean**, and **Cancel Send** choices. Cleaned
attachments use names such as `report-cleaned.docx`. The original email stays
unsent if cleaning or verification fails. Error reports support text selection
and **Ctrl+C**, including the recovery location when originals must be retained.
For the complete send workflow, cleaning selected attachments without sending,
and recovery instructions, see [Outlook attachment cleaning](/docs/integrations/settings/#clean-outlook-attachment-metadata-with-margindiff-scrub).
Cleaning only selected attachments can move those files after untouched
attachments in the email's attachment list.
