Lightroom Classic Data Files

I have on my Mac several versions of lightroom Data Files, it appears that every now and again it creates a new file, and gives it a new number.  My question is can I safely delete the older versions of these Data files or will I lose some of the data that lightroom needs to function?

 

Here is what is on my Mac:

 

Temporary Import Data.db-journal

Temporary Import Data.db

Temporary Import Data-4.db-journal

Temporary Import Data-4.db

Temporary Import Data-3.db-journal

Temporary Import Data-3.db

Temporary Import Data-2.db-journal

Temporary Import Data-2.db

Photos.lrcat

Photos-2.lrcat

Photos-2-2.lrcat

Photos-2-2-2.lrcat

Photos-2-2-2-2.lrcat

Photos-2-2-2-2 Sync.lrdata

Photos-2-2-2-2 Previews.lrdata

Photos-2-2-2-2 Helper.lrdata

Photos-2-2-2 Helper.lrdata

Photos-2 Previews.lrdata

Lightroom 4 Catalog.lrcat.lock

Lightroom 4 Catalog.lrcat-journal

 

 

In addition if I can delete some of these Data files can I therefore change the data file name in that I mean removing the  number/s to Photos.lrcat which was I believe the original data file name. Or will this cause problems?

Whenever Lightroom needs to upgrade the catalog, it creates a copy and adds "-2" to the name. That copy is then upgraded. What you see here is a long history of old catalogs that were upgraded, so most of them could be trashed. It's a bit difficult to say which is the one you really use. There is a previews file for the 'Photos-2.lrcat' catalog, but also for the 'Photos-2-2-2-2.lrcat' catalog, so both seem to have been used. Because only the 'Photos-2-2-2-2.lrcat' catalog has a 'sync.lrdata' file, my educated guess is that this is the one.

 

If you want to know for sure, start Lightroom and either look at the top of the main window, or look in the Catalog settings - General tab. There you can see which catalog is in use when Lightroom is running. The others can be trashed, unless you would use multiple catalogs for some reason, but it does not look that way.

 

The .lock file is an old file from a catalog that does not seem to exist any longer. This file, the .lrcat-journal file and all the Temporary Import Data files can be trashed too.

Since your list included a .lrcat.lock file you are looking at the folder your catalog is stored in while LrC is open (otherwise you had a crash and the .lock files was not deleted).

Close LrC down and have a look at that folder. You can, IMHO, safely delete everything other than the .lrcat file, the Previews.lrdata folder (although you can delete that and LrC will recreated the next time LrC is opened), the Sync data and the Helper data folder.

 

But it seems you have multiple catalog file in the same folder. Why are you using multiple catalogs? LrC is base on having all images in one catalog. It is fine to have multiple catalog if that is what you want.

This is strange there is a .lock file, however no matching .lrcat file. I think ACNPhoto needs to find the actual Catalog file that he is using at present before he starts deleting any files. See the screen capture.

Okay thanks, guys, I have deleted most of the files leaving the relevant files intact!

 

As for these two files:

Lightroom 4 Catalog.lrcat.lock   21 KB

Lightroom 4 Catalog.lrcat-journal 51 bytes

 

These are a throwback to the old Lightroom 4 program, which I originally purchased.  Therefore,  I imagine I can also delete these as well?

Yes certainly.

 

For me when LrC is open I have the .Lock file and a .lrcat-wal file. Once I close LrC those 2 files are deleted. This is on a Windows 10 system but I would suspect those 2 files would also be created and deleted on a Mac when LrC is opened and then closed.

I think the -journal file has been superseded with the -wal file
