Change catalog location of Windows System Image Manager

Question

I can't build the catalog of my image because it takes up 20 gigs and fills the hard drive. Can I change the working directory of the program to a drive with more space?

If I could make it use F:\ it could play with 400 gb instead of my ssd. And yes, the selected wim is on F:\
Moving the executables to F:\ (imgmgr.exe and dlls) doesn't change that it wants to use C:
Do I need to change some pagefile settings around?

Hi UpTide,
When creating the catalog, imgmgr.exe will mount the WIM file in current user's temp folder, which is under {%USERPROFILE%\AppData\Local\Temp}. See this picture:
For the Temp file location, we could change it through the following two way:
Navigate to Control Panel\System and Security\System, on the left side, click the
Advanced system settings, on the Advanced tab, click
Environment Variables at the right bottom, see:
Edit both the TEMP and TMP file location (value input) to the same location that you wanted, click OK.
Or
we may edit the TEMP and TMP value with registry:
HKEY_CURRENT_USER\Environment
On the right pane, change the above two values with the same location.
After that reboot to check if issue still insists.
