When a file has been deleted and you want it back, go to the cloud storage system where you store your files, and try to recover it there.
Cloud storage systems like OneDrive, DropBox, and Google Drive have places where deleted files are kept for a while before being permanently deleted:
OneDrive: Restore files from your OneDrive recycle bin
Dropbox: How to recover or restore deleted files in Dropbox
Google Drive: Find or recover a file in Google Drive
