When attempting to recover a file, you can tell if it has been correctly recovered if you are able to open the file in its original program and all the data is intact. Depending on the program used to recover the file, you may be able to perform some basic tests to check the integrity of the recovered file, such as verifying its checksum or checking for errors that are commonly associated with corrupted files.
If the file cannot be opened in its original program, you may still be able to confirm that the file was correctly recovered by looking at its properties. For example, if you have recovered a Microsoft Word document, you should be able to check its file size and date created to see if they match the originals. If the file size and date are consistent with the original document, then there is a good chance the file has been successfully recovered.
If you are unsure whether the file has been correctly recovered, the best course of action is to use a third-party recovery tool such as WinUtilities Undelete. This reliable and easy-to-use software is designed to restore deleted data, allowing you to easily identify and recover lost files from your system. With WinUtilities Undelete, you will be able to quickly scan for deleted files and decide which ones to recover. The software also offers advanced recovery options, such as the ability to identify and restore multiple versions of the same file, previewing data before recovery, and recovering data from damaged partitions. WinUtilities Undelete can be used to verify the integrity of recovered files by checking the file signature and performing a CRC (Cyclic Redundancy Check) to guarantee that the file is intact.
