Recover Files

You cannot recover data from an SSD after the Trash has been emptied due to how SSDs work.

If you have a backup, then you can restore the deleted files from a backup. If you don't have a backup, then you can try checking to see if you stored the files on some external media such as USB stick, external hard drive, or some cloud service (iCloud, One Drive, Google Drive, Drop Box, etc.).

You should always have frequent and regular backups. There is no excuse not to have a backup since macOS provides the Time Machine backup software included with macOS. Unfortunately this is one lessen that most people must learn the hard and painful way. FYI, cloud syncing services are also not considered a backup option.

If you emptied the trash, those files are gone. You'll need to restore from a backup.
