To recover a missing file from iMovie, first check the "Projects" or "Events" section to see if the file is still listed. If you can't find it there, look in the "Recently Deleted" folder within your iMovie library. If the file is not recoverable from these locations, you may need to restore it from a backup using Time Machine or another backup solution if you have one set up. Always ensure to back up your projects regularly to prevent future data loss.

export it from imovie, and you can import to imovie from file
There is not a website that allows you to save iMovie as a file, since iMovie automatically saves as a file.
The file name of an iMovie project typically ends with the extension ".imovieproj" for the project file. However, exported movies from iMovie are usually saved as video files with extensions like ".mov" or ".mp4". The specific file name can vary depending on how the user chooses to name the project or the exported video.
Click on the "Export" menu option in the "File" menu. After the export is done you will be able to import the file into iMovie
With iMovie or Final Cut
To copy an iMovie project from another computer, first locate the project file on that computer, which is typically stored in the "Movies" folder under "iMovie Projects." You can then transfer the project file to your own computer using a USB drive, external hard drive, or cloud storage service. Once transferred, open iMovie on your computer, and import the project file by dragging it into the iMovie interface or using the "File" menu to open it. Make sure you also transfer any associated media files if necessary.
Yes, you can. Just email the file (if the size is small enough) and have the recipient download that file and open it up in their iMovie software. Otherwise, you need to share it.
A .rcproject file contains details of an editing project from iMovie. It contains pointers to the original videos. To reestablish the connection to the video file the .rcproject should be put into the iMovie Projects folder within the Movies folder. When iMovie is launched the videos from the project will be available for exporting as a playable movie file.
Honestly, the direct upload from iMovie is not the best thing to do. It is better to export the video file and upload it directly.
If it's opening a previous project, just hit the red X button at the corner of the window. It will pop up the selection window for you.
YouTube does not take iMovie files. You must share the file as a QuickTime file (do not do full quality - that will make it a .dv file).
