Safely Isolate and Remove PowerPoint Temporary Files

Use this method to safely move and test temporary files before permanently deleting them, ensuring no active presentation data is lost.

PowerPoint generates temporary files while you work to manage clipboard data, AutoRecover information, and undo histories. While these files are usually deleted automatically, app crashes or improper shutdowns can leave them behind, consuming significant disk space. You can safely remove them by testing your presentations first.

1
Quit Microsoft PowerPoint

Ensure the application is fully closed. Right-click the PowerPoint icon in your macOS Dock and select 'Quit', or press Cmd + Q while the app is active.

2
Locate the Temporary Folder

Open a new Finder window. Press Cmd + Shift + G to open the 'Go to Folder' dialogue, then paste the following path: ~/Library/Containers/Microsoft PowerPoint/Data/tmp and hit Enter.

3
Move Files to the Desktop

Select the temporary files or the entire folder and drag them to your macOS Desktop. Do not move them directly to the Trash yet, as this serves as a temporary backup.

4
Test Your Presentations

Reopen Microsoft PowerPoint and open your recent presentations. Navigate through the slides to ensure all formatting, media, and data are intact and functioning normally.

5
Empty the Trash

Once you confirm that PowerPoint operates correctly without those files, drag the temporary files from your Desktop into the macOS Trash. Right-click the Trash icon and select 'Empty Trash' to free up storage space.

Safely Isolate and Remove PowerPoint Temporary Files
Safety Precaution: Moving the files to the Desktop first acts as a safeguard. If PowerPoint fails to open a recent file or exhibits missing data, you can easily restore the temporary files back to their original folder.

Frequently Asked Questions

Why does the PowerPoint temporary folder get so large on my Mac?

PowerPoint creates temporary files to manage AutoRecover data, rich media, and undo histories while you work. If the application closes unexpectedly or is not shut down properly, these files are not purged automatically, leading to a buildup of data over time.

Will deleting temporary files cause me to lose my PowerPoint presentations?

If you delete temporary files while PowerPoint is still running, or if you delete unrecovered AutoSave files before restoring them, you might lose unsaved work. Always save your active files and quit the application before clearing the temporary folder.

Where can I find PowerPoint AutoRecover files on macOS?

AutoRecover files are typically stored in a specific Library folder. You can find them by opening Finder, pressing Cmd + Shift + G, and entering ~/Library/Containers/com.microsoft.Powerpoint/Data/Library/Preferences/AutoRecovery.
