How to Clear Microsoft Word Cache: Quick Storage Cleanup Guide

That moment when Word freezes mid-document always hits at the worst time. I’ve lost count of how many crashes a bloated cache caused during my Microsoft days.

The fix is shockingly simple—just a few clicks to clear temporary files that slow everything down. No special tools, no registry edits, just straightforward cleanup that takes under 2 minutes.

You’ll free up storage space, stop random freezes, and get back to writing without Word second-guessing every keystroke. Works on any modern Windows version.

Between you and me, this is the first thing I do on any new machine. Prevents headaches before they start.

What Youll Need

Instructions

Here’s the procedure I follow to free up space and fix Word performance issues.

Shut down Microsoft Word completely—check the system tray to ensure no background processes remain. I always verify by opening Task Manager and ending any WINWORD.EXE instances, as these can lock cache files and prevent deletion.

Press Win + R, type %LocalAppData%\Microsoft\Office\16.0\OfficeFileCache, and press Enter. This path works for Office 2016 and later. For older versions, replace 16.0 with 15.0 (Office 2013) or 14.0 (Office 2010).

In the OfficeFileCache folder, select all files and folders by pressing Ctrl + A. Press Delete, then confirm the action. If you see a prompt that a file is in use, close all Office applications and retry—this usually resolves the issue.

For a more thorough cleanup, navigate to %LocalAppData%\Microsoft\Office\UnsavedFiles and delete everything there too. This folder stores auto-recovered documents and can bloat over time if Word crashes frequently.

Press Win + R again, type %temp%, and press Enter. This opens the system’s temporary folder, which often contains leftover Word files. Select all contents (Ctrl + A), then press Delete. Skip any files that refuse to delete—they’re likely in use by other apps.

Empty the Recycle Bin afterward to permanently remove the files and reclaim disk space. This step can free up several gigabytes if you haven’t cleaned the temp folder in a while.

Press Win + R, type regedit, and press Enter to open the Registry Editor. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Word\Data. Right-click the Data folder and select Delete. Confirm the action and close the editor.

This removes Word’s user-specific cache and settings. Don’t worry—Word will recreate the necessary entries on the next launch. If you’re uncomfortable editing the registry, skip this step and proceed to the next.

Restart your computer to ensure all changes take effect. After booting, open Word and check that it launches without errors. Create a test document and save it to confirm functionality.

If Word still behaves sluggishly, repeat the process and consider running the built-in Office Repair Tool from Settings > Accounts > Repair. This addresses deeper corruption issues that cache clearing alone may not fix.

Tips and Common Mistakes

These refinements to the process will save you time and prevent frustration when clearing Word’s cache.

Background Process Check: In Step 1, I can’t stress enough how important it is to completely shut down Word. Even a single WINWORD.EXE instance running in the background will lock cache files, making deletion impossible. Use Task Manager to verify no Word processes remain.

Version-Specific Paths: The %LocalAppData%\Microsoft\Office\16.0\OfficeFileCache path is specific to Office 2016 and later. For older versions, you absolutely must adjust the version number as mentioned. I’ve seen users waste time trying to delete from the wrong folder because they missed this detail.

Registry Backup Caution: Before attempting Step 4, always back up your registry. While Word will recreate the Data folder, a registry mistake can cause system instability. If you’re unsure, simply skip this step—the other methods will still free up significant space.

Verification Importance: After restarting in Step 5, don’t just assume the process worked. Create a test document with some sample text, save it, then close and reopen it. This verifies Word is functioning properly and that your cache clearing was successful.
