XnView Software

Hi, i have the problem that i have marked a lot of pictures and now when i want to open them it's telling me: There is an error.
I haven't changed anything. What can i do?

And one further question: What happens if i change the storage location on the computer, or if i even change it to an external hard disk?
Can i keep the markings of the pictures?

Thanks Kastanislaus

Ok sorry solved the problem by myself. I changed the name of the folder. Now i changed it back and i works.

But does somebody know how i can keep my markings when i transfer my pictures to an external hard drive?

Is there anybody who can answer my question??
I really would like to export the XNview settings with my pictures!

currently it's not possible

Ok thanks for the answer.
Not one that pleases me, but at least a clear answer

Is it possible with XNView MP?
I'm just wondering where does the programm save this information how a Photo is tagged?
Is it really like this that if i have to set up the computer new or if i buy a new one etc. that i loose all the taggings?

Then XnView seems like a very bad choice to manage all my photos?!

tag info is for temporary use, color label is perhaps better
