Thanks for replying..no worries:)
Well first of all, I wanted to let you know that there for some reason are two libraries. I dont know why. The system must have created the second library for some reason at some point, maybe it copied the first library?
I believe that all my photos are in the second library, since it is the largest file. I dont know if the first library is important or not. It would only be important if it contains pictures that I dont have in the second library.
I am not trying to merge the libraries..I only wanted to point out how they react when I double click on their icons: the first one came up with the message I wrote earlier..the second one opens my Photos app! So I guess its the second one that is my library of use.
So basically I just wanted your response before I tried removing my cache file.
Do I only need to delete my cache from the second library?
It will not delete any photos? (I have mostly photos that are from real cameras like canon etc)
Can I safely delete the first library (the one that apparently is not in use)?
How can I check the content of the first library before I delete it?
