Hi there,
When I'm trying to create panoramas, often Lightroom fills up the remaining space on my C Drive, and means I have to stop and restart. How do I point LRC to use a different drive for the Pano creation temp files? I have around 100gb free on C drive, and sometimes do large panos which take it down to 10gb and freezes the process.
I've got the camera raw cache saving to D Drive and is 200GB max size.
Apologies if this has been solved in the community, I haven't spotted it, but did see an unanswered post of identical issue, from 2016.
System specs - (If anyone can spot where my system is weak I'd be very grateful, if often struggles with large images). Running LRC 13.0.2 on Windows 11 Pro Version 10.0.22621 Build 22621

System info from LRC -
Many thanks! Leo
Lightroom doesn't have Photoshop's memory management with a selectable scratch disk.
It uses standard system paging, the system TEMP directory, which is always on the system drive (C). That's something you just have to live with for now. I agree that this is a shortcoming and a sensible feature request (but probably requires quite a bit of programming work).
At basic operation Lightroom isn't very memory or I/O-intensive, so there's no need for a "scratch disk". But all these new functions l

Do yo know what folder on the C drive gets filled up? A Temp folder? The Paging File? Some log file???

Thank you for the reply. No I haven't been able to find a file. Would a temporary file be hidden?

I assume you can go into Windows and change the default system TEMP directory, but I have never bothered looking into that.

Thank you for your knowledgable reply! So something no likely to change any time soon.
I'm surprised I haven't seen more about this. It might only affect large panos to this scale, so as there are many options for pano merging, might not be a high priority to Adobe.
I'd counter that to say merging in Lightroom has come on a lot, and having an editable DNG is a big bonus. I sometimes use PTGUI when the result isn't good, but this requires pre editing and the expsoure blending isn't very good. And the merging in Photoshop is a longer work process and often the result is way off, LRC is more accurate.
Thanks again!

You could add another SSD, nothing special, and relocate the Windows Paging file and the temp directory to it. I would keep the Camera RAW CACHE folder that LrC and Adobe Camera RAW uses (same folder for both) separate, that is not on the drive with the paging file. (not to be confused with the PS Scratch disk).
