Saving new file VS overwrite

[MaxenceH]

Hello, 

I have the lastest version of illustrator. But I realised that when I save my file, it doesn't save unless I save as a new file. 

Why and how can I fix this? 

Thanks for your help.

Where do you save? Local, like desktop or a cloud synced folder or server?

I save it on my personal server, a WD Home Cloud Duo. It works like a regulard local disk. I've never had this issue, altought I just changed my computer...

Illustrator does not support saving to a server. It may work, but the safe way is to save local and when finished, copy to a server,

It worked fine for years under windows 10, and I just switched the windows 11 with a new computer. Could that be the source of the problem? 
Somethign else that is weird, in the preview pannel in illustrator, before opening any file, I can see the preview of the file with all the lastest change I have saved using ''save'', but then I open the file, it's just like when I opened it before....

That's a sign that your files aren't saving completely. Don't save to a network. It can work and then suddenly not. And also you might want to turn off "Save in background" in the preferences

Thanks !!! 

Save in background did the trick! It works fine now
