You can the limit to the Video cache size.
Please follow the steps :
> Launch Lightroom
> Click on Edit > Preferences
> Click on File Handling Tab
> Enable Limit video cache size and provide the maximum size limit.
Let me know if this helps.
After making the changes in Preferences, please restart the computer and see if it helps.
I have the same problem. My video cache limit is set to 3GB in Preferences (I think this is the default; I don't recall changing it). However, my Media Cache folder has bloated up to 60GB.
Can the .cfa files simply be deleted safely?
Answering my own question: Yes. I made a backup, and then deleted everything in the Media Cache folder manually. No problems noted.
I never would have discovered this problem without WinDirStat, which is a great free tool for visualizing your disk space use.
Not only does the cache size limit not work, the "Purge" option in Preferences also has no effect.
manually deleting files in AppData\Local\Adobe\Lightroom\Caches\Video\Media Cache Filesr is NOT a solution! OR Its just a very short-term solution..
If you have in (LR -> library -> folder) video and picture files, after folder syncro they are again writen (in video cache folder)..
And the size of this folder increases over time..
Can I force LR to not use this video chace for video files? ...
Hi R - I think I may have misunderstood your situation - I missed the sync part. I think my problem is just a bug, wherein Lightroom is ignoring its own cache limits, so that the video cache increases to an unreasonable size.
What are you using to sync the folder? - Tom
