There are several causes why files won’t open after data recovery: File damage during recovery: recovery tools may recover files only partially or recover them in a damaged condition. Recovery of incomplete files: files were overwritten partially or some part of data is missing. Incorrect file structure recovery: Some tools can recover files without restoring their correct structure or metadata required for them to open properly in editors or specific applications. Files damaged before being lost: If files were damaged or unreadable before loss of data, their recovery doesn’t guarantee that they will be fixed.
