68GB delivery optimization file for Windows 10, cannot be deleted
Windows 10 includes a 68GB optimization file designed to improve performance, but it occupies a significant portion of the M.2 SSD space. The system prevents deletion of this file, which may seem unusual since it wasn’t present before. Removing it is possible, though you’ll need to access the installation folder and locate the file manually. Its size has increased over time as more features were added.
Based on my search, Disc Cleanup helps remove files that might interfere with system performance. It can also speed up and improve the reliability of Windows updates. For more details, check the Microsoft privacy page about Windows updates.
I attempted that and restarted afterward, but it didn't resolve the issue. Unfortunately.
Hello, the file appears to be quite small—just around 8MB. Windows Disk Cleanup confirms this. In the program’s allocated column, you’ll notice an on-disk directory size of about 11.8MB, which includes roughly 2MB of metadata and 8MB of actual data. When you open Explorer and inspect the folder, the "Size" and "Size on disk" values will differ significantly. The "Size on disk" is the key metric that reflects the real space used on your drive by files and folders. For a clearer picture of what’s occupying space, consider using a tool that compares reported versus actual file sizes.
The differences you're noticing stem from how Delivery Optimisation constructs a virtual directory structure for your Windows setup. It incorporates user registry entries and all files from the SxS directory, creating a comprehensive tree without storing every single file permanently. Only changes between patches are saved, which explains why the folder size appears larger than the actual data. When a full update was applied, the system compiled roughly 633MB of content, resulting in much smaller delta patches for faster downloads and installations.
