Bonjour à tous,

I suspect you only use the latest catalog, which seems to be v13-3. Looking at the dates of the files seconds this.

That said, you probably don't need the older stuff anymore. If you open one of the older catalogs, it would be upgraded again.

The latest catalog contains all your data - NOT photos! It looks as if it was updated from the first catalog to v11, v12, v13 and to v13-3 with the update LrC 13.3.

Move all the rest to trash or to some temporary folder and test if everything is still working as expected with 13-3.

sorry, my english is not enough good but this is what I did : 
save in an external hard disk all my picts and create a new catalogue to start cleanly
thank you so much for your time

Do not keep backups on the same physical disk as the working catalog! This is a recipe for disaster. Backups MUST be on a different physical disk.
