Hi, I had made a 12 minute video for youtube over the coursse of 3 days, I go to export it but not enough space on my laptop so I purchased a but more, upon exiting PrPro the project asked me if I would like to save, I clicked yes and continued to buy storage, when I open the software back up, the project is gone, the newst on says "4 days ago" how do I get this video back and why, if I saved the project, would it just be gone like that?
Since you remember saving, there's a good chance you can find the project file.
Look for a .prproj file where you saved it with the file name that you gave it. The project file is named, a location chosen, and saved at the very start of a project - so that's when you would have first picked a name and location.
If you're not seeing it in Explorer/Finder, try searching for ".prproj".
It may be called "Untitled.prproj".
A location to check is Documents/Adobe/Premiere Pro/23.0 (the last folder in that path will be named based on the version number of Premiere Pro that you are using).
When starting a new project, Premiere Pro shows recently used locations in the Project Location pop-up menu. You could start a new project and check the file paths shown there to help locate your project file.
