2 premeiere pro project files have been disappeared, even auto save files.

Hi @원5D19, 
I'm sorry to hear you can't find your Premiere project files.  Making sure Hidden Files are turned on is always helpful.  A few follow-up questions:  Is the path you sent where you keep your project files? Did you check your Recycle bin?  Always worth double-checking.  You said you see them in the recent projects when you open Premiere?  What happens when you try to click on one of them?  Do you set all your auto saves to go to the same place, or do you change it per project?  Can you see the autosaves of other projects, and just these two are missing, or can you not see any autosaves?

Did anything change before you lost your files?  Did you update Premiere/ your OS/ etc?  What version of Premiere were the files created in?  What version are you currently using?  We need a few more details to help with this issue. Please see: How do I write a bug report?

I hope we can help you soon. Sorry for the frustration! 

You would have to search the drive, and do include 'hidden files' in the search parameters. Premiere doesn't delete project files except on a couple very rare times with specific versions.

However, it doesn't always do auto-saves until the user has manually saved. That's happened occasionally to people, and it shouldn't but I've had that happen once also.  Autosaves should always be to a different drive than the 'normal' project files. For safe computer practice.

And also, you might check read/write permissions. That can be an issue at times also.
