How big can a Photoshop Elements catalog be?

I have over 150,000 media files, photos and videos, in my main catalog.  (All of my files have been through face recognition analysis, but my catalog has been built over many years.  With the introduction of video face recognition in 2020, it did take several days of 24/7 operation, as mentioned, to analyze my 10,000 video files.) 

With a large catalog, it does take longer to load the catalog on startup and certain operations do take longer.  But a calalog that is under 100k files should load fairly rapidly with adequate computer hardware.

My catalog is approximately 108000 photo's large and still works. I did however chose to make some additional catalogs for photo's of specific projects (that i did not want in my "main" catalog). Still works fine.
In my main catalog i did not complete the face reconigion. i have tried, but it's crap. Takes wayyyyy to much memory (more that specified max allowed, so the compuetr crashes), and it takes a longggggg time (weeks and weeks of 24/7 running).

So if you have "only 25000 foto's and want to use face reconigion, i would suggest starting with it asap.

Hi Reser,

There is no limitation on the number of images you can have in a catalog or how large the catalog can be in Photoshop Elements however a larger catalog may slow down the performance of the application.
