- Scenario
- Cleaning up the Downloads folder or freeing up hard drive storage space after successfully installing Microsoft Office.

Safely Delete the Installer File to Free Up Space
Once Microsoft 365 is installed and activated, the IMG installer is no longer required for normal operations and can be safely deleted.
The Microsoft 365 IMG file acts as a virtual disk containing all the setup data required for offline installation. Once the software is installed on your system, this file serves no active purpose unless you plan to reinstall Office without an internet connection.
Open File Explorer or Finder and navigate to your 'Downloads' folder, or the specific directory where the 'O365Retail.img' file was originally saved.
Right-click the Microsoft 365 IMG file and select 'Delete' (or move it to the Trash).
To permanently free up the storage space on your hard drive, right-click the Recycle Bin or Trash icon on your desktop and select 'Empty Recycle Bin'.
Back Up the Installer File Externally
If you have a slow or limited internet connection, you may want to keep the IMG file on an external drive for future offline installations.
