Additionally, Search of All VATs allows you to quickly find and recover the lost files and folders on write-once discs (CD-R/DVD-R/DVD+R/DVD+R DL/BD-R). This option looks for so-called Virtual Allocation Table (VAT) that is being placed on the disc physically when you eject it from your computer drive. VAT's location is crucial for the disks created with the help of drag-and-drop software, such as well-known Roxio (Adaptec) DirectCD and Drag-to-Disc. For example, after you have accidently deleted some files and folders, a new VAT does not point to them. To recover the deleted files, you should use the previous VATs.
To start a search of all VATs, you should check the box with the same name under UDF Reader tab in the program preferences, and then click the Refresh button for a new analysis of inserted disc.
Using found VAT, the program restores an old backup and shows it as a separate session. Further, just use a built-in Session Selector to look into each backup (session).Finally, Scan UDF Disc allows you to recover the files data from all types of UDF discs that are not working properly. Scan UDF Disc gives you a good chance to retrieve several types of files, including:
- files are not visible in Windows Explorer - the writing process was interrupted by a system or power failure before file directory information was completed, but most or all of the files were written to the disk. This means that the files may be on the CD (DVD, BD), but Windows Explorer cannot see them.
- lost files - complete files that do not have a file name associated with them. They can also be files that you accidently deleted from the CD (DVD, BD).
- files on the disks quick-formatted by Roxio DirectCD and Nero InCD.
- files located on Sony Mavica CD finalized with failure on the camera. Forced scan is recommended.
- M2TS files on the discs that were not finalized by AVCHD camcorders. Forced scan is recommended.
- files located in unreadable (damaged) UDF folders.
When using Scan UDF Disc, you can save the table of contents (names, locations, attributes) of the found files into a separate file. Next time, this will allow you to display the list of files shortly, without a new scan of the same disc, and you can continue to recover the files data. Some lost files found by Scan UDF Disc can be recovered only with the file name disassociated from the data. With the help of built-in File Identifier, you can simply identify the found files by their content and assign the proper extension to the file so that Windows application can open the file.
