Is There Any Way to Recover a Deleted Dissertation on a Mac?
Asked by

I accidentally deleted the latest version of my dissertation and then emptied the Trash without realizing it. The only version I can recover is from mid-2025, which is missing months of work. I checked Word's recovery options and temporary files, looked for a cloud copy, and ran Disk Drill. Disk Drill recovered much older documents, including papers from around ten years ago, but somehow did not find the dissertation. I also didn't have Time Machine enabled because my drive was full, and nobody else has a copy of the latest version. Is there anything else I can try, or is professional data recovery my only remaining option?

Check every possible Word and cloud-storage location, especially OneDrive, Word’s temporary-file folders, and autosave or recovery directories. On a Mac, some Word temporary files may appear in a Microsoft Word container under a tmp folder and have names beginning with “WRD.” Search Finder for that pattern as well as distinctive words from the dissertation.

You’ve already tried one recovery program, but different tools can produce different results. Before trying more software, make a full image of the drive or have a professional handle it; installing and running recovery programs on the same drive can overwrite the deleted data. Unfortunately, recovery software cannot restore a file if its storage space has already been reused.

Stop using the computer as much as possible and take it to a reputable professional data-recovery service. Continued use can overwrite the deleted file’s data, making recovery less likely. There’s no guarantee, but professional recovery is probably the best remaining chance.

If you ever had Time Machine or local snapshots enabled, search the entire Mac by filename and by distinctive keywords from inside the document. Also check for printed drafts, exported PDFs, email attachments, shared copies, or earlier files that could be scanned and converted back into editable text. Since Time Machine was not enabled and no one else has the latest copy, the recovery options may be limited.
