Question

available room on SSD on my Mac mini M1 disappeared quickly

Hi ---

 

I am using 13.5.1 on my Mac Mini M1 with a 1 TB SSD.   The available space on the drive decreased from 400 GB to 100 GB quickly.  I recall having the same issue about a year ago.   Possibly related to a Forced Quit of  LR which created a very large backup file on the SSD.  I was able to delete the backup.

 

I realize this may not be enough info for a diagnosis.   Please let me know what additional detail is needed to find a solution.

 

Thanks!

It could be a lot of things. OmniDiskSweeper or DaisyDisk should show you in detail where the room is going.

For Lightroom Classic, previews will take up a huge amount of drive space, its easy to go over a TB. Consider moving the catalog to an external SSD.

Thank you Lumigraphics, that is a good suggestion.   I've already moved the catalog to the same external drive that has my photos.   I plan to try DaisyDisk, as OmniDiskSweeper is not finding anything out of the ordinary that is eating disk space.

Thank you!   This one is closed.    The culprit was the crash report logs.    DaisyDisk provided the necessary intel.

Hello,

If you have done a force quit of Lightroom Classic, then there is a place you can look at. Look in LocalLow folder - Users/your name/ AppData / LocalLow/Adobe/CRLogs and dumps. You just might find a few gigabytes worth of crash files.

 

You will have to enable Show Hidden items to get access to the AppData folder.

Recently after I wondered where all the space was going I found I had around 95 GB of dump files.

So it could be worth a look there.

Of course, this is for Windows, but there may be something equivalent for a Mac.

On a Mac these should be in Username/Library/Application Support/Adobe/CRLogs and dumps. I can't check it right now because I type this on my iPad.

Could be anything and not necessarily related to Lightroom Classic at all. The first thing to check is the cache folder:

Users/YourUserName/Library/Caches

Do note that the User/Library folder is hidden by default. Here's how to unhide it: https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html

Another good method of trying to find out is to use an app like DaisyDisk.

Thank you Johan,

 

I use OmniDiskSweeper which is somewhat similar to DaisyDisk.  (which looks very interesting to me, so I will be adding it to my toolkit later.)

 

I looked in the folder:  Users/Myname/Library/Caches/ Adobe/Lightroom/Cache/.   "Get Info" showed only about 1 gig in that folder.   So that is not the culprit.  Should I be looking elsewhere?

 

Thanks again!

Are you talking about Lightroom (Lr icon) or Lightroom Classic (LrC icon)?

 

I would imagine you should be looking everywhere on the disk.

 

Where are the photos themselves stored?
