Can I get a deleted file back?

Yes. Deleted files go to the Bin in Files and stay there for 30 days

To restore: open Bin, right-click the file and choose Restore. It returns to the folder it came from

Good to know:

• Right after deleting, click Undo in the message that appears, or press Ctrl+Z (Cmd+Z on Mac)
• Delete permanently in the Bin is final
• Deleted chats are in the Bin too
• Files in the Bin still take up storage
