Word creates several support files, but they are not interchangeable. An .asd file is an AutoRecover candidate, a .wbk file can be a Word backup, and a .tmp file may contain little reusable content. Start with Word's recovery commands before searching thousands of unrelated files.

Best order: Document Recovery, Recover Unsaved Documents, Word's configured AutoRecover location, targeted extension searches, then cloud history or backups.

Understand the useful file types

FileWhat it may representConfidence
.asdWord AutoRecover dataHigh when time and size fit
.wbkWord backup copyHigh if backups were enabled
.docx or .docNormal saved documentVerify path and time
.tmpTemporary application dataLow until a copy opens
name beginning ~Often a lock or owner fileUsually not the document

A promising extension can still be old, incomplete, or unrelated. Content verification is mandatory.

1. Let Word identify recovery files

  1. Reopen Word after the crash.
  2. Review items in Document Recovery whose timestamps fit.
  3. Open a candidate and use Save As with a new filename.
  4. If no pane appears, use File > Info > Manage Document > Recover Unsaved Documents.

The newest timestamp is a starting clue, not proof. Keep other candidates until the selected document has been checked and reopened.

2. Read Word's actual AutoRecover path

  1. Open File > Options > Save.
  2. Copy AutoRecover file location.
  3. Open that path in File Explorer.
  4. Sort by Date modified.
  5. Copy likely .asd files to a holding folder.

This is safer than trusting a universal path because profiles and managed Office installations can differ.

3. Search Windows by extension and time

  1. Search for *.asd in the expected folder and user profile.
  2. Search for *.wbk if backup creation may have been enabled.
  3. Search for *.docx and *.doc to find a misplaced normal file.
  4. Search for *.tmp only after higher-value searches fail.
  5. Copy plausible results into a dated recovery folder.

Enable View > Show > File name extensions so Windows reveals the real type. Record each candidate's original path before copying it.

4. Test a copy in Word

In Word, select File > Open > Browse, set the filter to All Files, and select a copied candidate. If normal opening fails, use the arrow beside Open and try Open and Repair.

Judge the result by remembered evidence: the final heading, a distinctive sentence, last table rows, comments, tracked changes, and page count. File size and modified time help rank candidates but cannot prove completeness.

Do not rename or repair the only candidate. Save anything useful as a new .docx, close Word, and reopen it before declaring success.

5. Check cloud version history

If the document was stored in OneDrive or SharePoint, preview Version History around the loss. AutoSave writes eligible cloud changes frequently, while AutoRecover periodically protects against interruption. A cloud version can be newer and structurally cleaner than a local .asd.

Save or download a separate copy when comparison is safer than replacing the live file.

6. Match the method to the loss

  • Deleted document: check the Recycle Bin, OneDrive recycle bin, and backups.
  • Overwritten cloud document: use version history.
  • Corrupted existing file: use Open and Repair on a copy.
  • Permanently deleted local file: stop writing to the source drive and consider Windows File Recovery.
  • Closed with Don't Save: recovery may be unavailable because Office treats that choice as intentional.

Microsoft warns that deleted-file recovery becomes less likely as new data overwrites free space. Windows File Recovery must write recovered files to another drive.

Keep a simple evidence log

For each candidate, note the original path, extension, modified time, size, whether it opened, and newest verified paragraph. This prevents replacing a good but incomplete document with a larger, older file. Once the right version is confirmed, save it normally and reopen it before removing other copies.

Confirm that recovery is actually complete

Check beyond the first readable page. Search for a phrase from the final editing session, inspect the last table and image, and review headers, footnotes, comments, and tracked changes. Then use File > Info to confirm the recovered copy has the expected page count and a new save location. Close Word completely and reopen that saved copy.

If one candidate has newer text but another preserves better formatting, keep both. Move verified text into a duplicate of the structurally sound file rather than repeatedly repairing either source. This preserves a reversible path and makes the final document easier to audit.
