O&O DiskRecovery 9 Product manual

O&O DiskRecovery 9 
Adding Your Own Signatures

After starting O&O DiskRecovery you can open the dialog box to add your own user-defined signature.

After the dialog box appears, please enter the File Extension for the new signature (e.g. DOC for a Word document). In the Short Description, you may enter a small narrative regarding this file type.

The Start Position defines the offset of the signature calculated from the beginning of the file. For instance, if the signature is to begin from the third character, then enter a 3 here. Otherwise, enter 0 when the signature is to stand at the beginning of the file.

The use of place holders is also a possibility while defining a signature. A place holder stands for any user-defined character in the signature. For this, you need to activate Use Place holders. Afterwards you can define "?", "*", or any other character as your place holder.

In the field labeled Signature you can enter the distinct character chain that is used to identify the file type. This can be entered using any ASCII characters. If you would like to enter a special character that can not be expressed through normal text, enter a dollar sign instead. Following the Dollar sign enter a two-digit Hex value in place of the character. For example, if you would like to add a line break (Carriage Return corresponding to ASCII Code 13), then you would have to enter '$0D'. Entering a '$$' will produce an actual Dollar sign.

It is also possible to enter Hexadecimal Values. For non-displayable characters it is recommend using only Hexadecimal values.

After you have finished entering the signature, it is necessary that you save it. Please note that all user-defined signatures must be saved either to the O&O DiskRecovery program folder or to your 'My Documents' folder for them to be found and loaded when the program starts.

If you would like to change a signature already created and incorporated into O&O DiskRecovery, simply load the desired signature and save it again with the desired changes.

Detailed information on how to create signatures are available on our Website.
