O&O DiskRecovery can recognize over 300 different versions of file types. A complete list of these file types can be found in the section entitled List of Supported file types.
Moreover, you have the ability of adding your own signatures. O&O DiskRecovery can use these user-defined signatures for its scan.
If you notice an important file type is missing from the current list and should be included, please give us three examples of this file type with a short explanation and send them to support@oo-software.com. We will then incorporate this file type into the new version of O&O DiskRecovery. Please note that we are not liable for any data sent to us. If you have any questions regarding this, please feel free to contact our Technical Support.
