What computer operating system is your Premiere Elements 12.1 running?
1. The program as an AutoSave feature which you can set to take a designated number of "snapshots" of the project over a designated period of type. See Edit Menu/Preferecnes/AutoSave. This appears to be the automatic way of doing what you are doing with your manual saves as you progress through your project.
Please review and go with what works for you.
What is the problem? If you do not need one of your saved intermediate projects, what is the problem in just deleting it? You have the latest version of it? Have you considered incorporating an external hard drive (formatted NTFS if Windows) into your computer environment?
2. The recommended way is to beforehand set up a folder for each specific project and direct the project's file to it.
So, when it comes time for deleting a project, you have one folder to target, and you do not have to go through each of the folders in the Adobe Folder to find files with the name of the project for deletion.
- See Edit Menu/Preferences/Scratch Disks for designating save locations for specific files.
- See Libraries/Documents/Adobe/Premiere Elements/12.0 for the Adobe Premiere Elements AutoSave Folder, Adobe Premiere Elements Previews FIle Folder, etc. where the actual named files will be automatically placed.
- Remember, the save location for the project.prel is the new project dialog (See File Menu/New/Project).
Major thought is never to delete the source media that went into the project after the project is saved/closed. And, when it comes time to delete the project, make sure any of its media were not being used by more than this one project for deletion.
