Question details

The user needs to understand the purpose of the Office SolutionPackages folder and verify if deleting its contents to free up storage space is safe.

Product: Microsoft Office
Device & OS: Windows
Scenario: Reclaiming system disk space, particularly in Remote Desktop Services (RDS) environments where multiple profiles exist.
Observed behavior: The SolutionPackages folder located in the AppData directory is growing excessively large and consuming a significant amount of local disk space.

Before you start

Ensure that all Microsoft Office applications are completely closed before making any changes. It is highly recommended to copy the SolutionPackages folder to another location as a temporary backup.

Solution 1Recommended

Safely Delete the SolutionPackages Folder Contents

Manually clear the cached files within the SolutionPackages directory to instantly free up disk space.

The SolutionPackages folder is used by Microsoft Office to store cache data for add-ins and templates. Over time, especially in Remote Desktop Services (RDS) environments, this folder can grow excessively large.

Deleting the contents is safe. Office will automatically recreate the necessary files and rebuild cached data for active add-ins the next time you launch the application.

Close Office Applications

Exit all running Microsoft Office programs, including Word, Excel, PowerPoint, and Outlook.

Open File Explorer to the Target Path

Press the Windows Key + R to open the Run dialog, type '%localappdata%\Microsoft\Office' and press Enter.

Locate and Backup

Find the folder named 'SolutionPackages'. Right-click it, select 'Copy', and paste it to your Desktop or another safe location as a backup.

Delete the Contents

Open the 'SolutionPackages' folder, select all files and subfolders inside it (Ctrl + A), and press the Delete key.

Cache Rebuilding: The next time you open Office, some add-ins or templates may take slightly longer to load initially as they rebuild their required cached data.

Solution 2

Clear the Office Document Cache via Settings

Use the built-in Microsoft Office settings to clear document caches, which can help reduce your overall Office storage footprint.

Frequently Asked Questions

Why does the Office SolutionPackages folder get so large?

In environments with multiple user profiles, such as Remote Desktop Services (RDS), or when using heavily data-dependent add-ins, Office continuously caches package files for quicker loading. This cache data accumulates over time and can consume significant storage space.

Will deleting the SolutionPackages folder break my Office add-ins?

No, deleting the contents of the folder is generally safe. Active add-ins will simply recreate their necessary cached files the next time they are used, though they might take slightly longer to load on their very first launch.

Can I prevent the SolutionPackages folder from growing again?

There is no native setting in Microsoft Office to strictly cap the size of this specific folder. You may need to perform routine manual cleanups or use a lightweight alternative office suite like WPS Office if local storage space is limited.

What happens if I delete the entire folder instead of just its contents?

If you delete the entire SolutionPackages folder rather than just the files inside it, Microsoft Office will typically recreate the folder structure upon the next launch. However, it is generally safer to just clear the contents to preserve original folder permissions.
