Catalogue Lightroom

[Guido Pipers]

My catalogue is larger than 4 GB, but there are only 358 photo's in it.

How can I reduce it?

Try optimizing the catalog: http://lightroomkillertips.com/its-lightroom-optimize-your-catalog-day/

btw. the photos are not in the catalog. They are wherever you have imported them from/to.

The size you are quoting is the size of the lrcat file?

What is your OS and the exact version of LR?

Thanks for your answer.

Optimizing the catalogue has been done several times but without result.

Currently I am using CC 2017.0.1, but I had the problem before I upgraded from Lightroom 4 and Photoshop CS6.

I am aware of the fact that the photo's themselves are not in the catalogue, but all the manipulations are. (I keep track of the history)

I am using an iMac 27" late 2013, macOS Sierra version 10.12.3

If you are getting this error message, then the message itself is a mistake and you can ignore it.

Yes, if it's about backup error, this is it: Unable to back up the catalog in Lightroom CC
