Question details

The user needs to safely delete a large Microsoft Word cache folder (e.g., up to 12 GB) on a Mac to free up storage without causing data loss or syncing errors.

How to Safely Clear a Large Microsoft Word Cache on Mac

Product: Microsoft Word for Mac
Device & OS: macOS
Scenario: Reclaiming Mac storage space consumed by heavily oversized Microsoft Word application cache and container files.
Observed behavior: The Microsoft Word container folder has grown extremely large, and the user is unsure which files are safe to delete blindly without breaking the application.

Before you start

Before modifying any system or application files, ensure you completely quit Microsoft Word and copy the target folder to your Desktop as a temporary backup to prevent accidental data loss.

Solution 1Recommended

Clear Temporary Cache Files via macOS Finder

Locate and remove only the temporary cache files manually from the hidden Library folder to ensure application stability.

Cache files help Microsoft Word load documents faster and manage offline data, but they can swell to several gigabytes over time. Deleting files blindly in the Library container can cause sign-in drops or loss of unsaved documents, so it is vital to target specific cache directories.

Quit Microsoft Word

Press Command + Q or right-click the Word icon in your Dock and select 'Quit' to ensure the application is completely closed.

Open the Library Folder

Open Finder, press Command + Shift + G to bring up the 'Go to Folder' window, type '~/Library/Containers/' and press Return.

Locate the Word Container

Find the folder named 'Microsoft Word' (or 'com.microsoft.Word' on older macOS versions). Copy this entire folder to your Desktop to serve as a backup.

Delete Target Cache Files

Navigate inside the Word container to Data > Library > Caches. Select the files inside this Caches folder and drag them to the Trash.

Restart and Verify

Reopen Microsoft Word and test its performance. If everything functions normally and your documents are intact, you can safely empty the Mac Trash and delete the Desktop backup.

Clear Temporary Cache Files via macOS Finder

Data Safety Warning: Do not delete the entire Microsoft Word container folder. It contains your application preferences, normal.dotm templates, and AutoRecovery files, which will be permanently lost if removed.

Frequently Asked Questions

What happens if I delete the entire Microsoft Word container folder?

Deleting the entire container will remove your customized settings, custom dictionaries, macros, and AutoRecovery files. It essentially resets Word to its factory default state, which can lead to unwanted data loss.

Why does the Word cache grow so large on a Mac?

The cache stores temporary files, font caches, clipboard data, and offline versions of OneDrive documents to speed up workflow. Frequent use, large image attachments, and delayed syncs can cause this folder to swell over time.

Can I use a third-party Mac cleaner app to clear the Word cache?

While cleaning apps can automate the process, they may aggressively delete necessary container files. It is generally safer to manually review and clear only the specific Library/Caches folder to maintain control over your data.
