If you’re having trouble deleting an Adobe Premiere project file, there are a few things you can do to try and fix the problem. First, make sure you have the correct file extension for the project you’re trying to delete. If the file extension is not .ppm, .mpeg, or .avi, then it’s not a Premiere project file and won’t be deleted. Next, try renaming the file if it’s not being deleted automatically. Finally, if all else fails, you can try deleting the project file from your computer and re-creating it from scratch. ..
