It overwrites these files at every save.
At any given time you will only have 2 saves of this name in folder 4.
When the diamond appears it means saving is in progress and should exit when finished (a few seconds).
If however, the diamond stays animated during gameplay, take this as a warning that something is wrong. It will not save again past this point!
Some say to disable online storage and save locally, but It made no difference to saving and I lost about 16 hours of gameplay. I made contact with Ubisoft support and their replies and fixes seemed to be a "stab in the dark".
They seemed to think I was the only one who had a problem. Then, after following all of their suggestions (with no end to the problem) they said it may be due to SpyBots port watching activity and since uninstalling and deleting all traces of the program, I have not had the problem.
I hope you have luck with yours!
