Nel programma c'era un "Recovery Mode". Cito testualmente dalla pagina di quando era distribuita la versione 4.5 (l'ultima freeware) che mi ero salvato su un CD:
The purpose of this mode is to recover messages that have been deleted from the deleted items folder. With the DBX files, Microsoft chops each message into 512 byte pieces. When a message is deleted from the deleted items folder (that has not yet been compacted), then OE removes the first 4 bytes of each piece, so it is not possible to recover a message in its entirety. However, with this version of DBXtract, one can recover from the deleted items.dbx file, such pieces that are still there and reassemble what is left of the pieces. To accomplish this, check the Recover Mode box. Then browse to the deleted items.dbx file and set the output directory. Then click the Extract button. A set of text files will then be extracted into the output directory. For the sake of completeness, all fragments will be recovered. A lot will have the filename NoSubject appended by a number. Most of these will be redundant and can be deleted (Make sure the by Subject check box is checked when using the Recover Mode feature, so one can distinguish between them). Images and other attachments will be incomplete and likely irrecoverable, but text and message headers should be largely intact.
Recover mode will also work for messages that have been Shift-Deleted from other folders.
