Q: I have just purchased CDRoller, and though i have identified the missing files, i cannot do anything with them, i.e open and copy to a HDD. Are there instructions?
A: First, please make sure you have registered CDRoller with the help of your license key. If yes, have you closed the program after that? If not, please close CDRoller and start it again without any disk(s) inserted into the drive(s). Then, please select Help/About option and look at the 'About' dialog. Do you see the '(Registered)' near the version number? If the problem still exists, please consult our Support Dept. at support@cdroller.com.

Q: I have copied back up files to a CD-R in several stages, but the last time I backed up, I was only able to see the most recent batch of files. The others seem to have disappeared... I presume they are still there on the CD but "hidden" in some way - may be a different volume ?
Q: I am trying to recover some data from a CD. Using CDRoller, I can now at least see (and access) some of the files on it. However, it seems like many files are still missing. However, I ran the "Disc Test" and can see that there are several tracks with varying amounts of data on each of them. Is there a way to access each of these tracks independently to recover my data?
A: Please try Session Selector built in CDRoller. Your CD seems to contain more than one session. In CDRoller 5, in order to select a new session, you should right click on CD name in the List Window and use 'Session' command from pop-up (context) menu. You can also select a disc first and then use 'Session' command from File menu.

Beginning on CDRoller 6.0, a list of available sessions is simply displayed in the main program window. Just click a new item with 'Disc Session' type to select a new session.

By default, CDRoller manages folders and files from the last session, placed on the disc. Using Session Selector, you can access to the data of all sessions recorded on CD or DVD.

Q: I burnt my DVD in several stages with Roxio Easy Creator Classic 6. However, only the files from the first backup (session) seems to be shown. Why? How i can see the files from the second, third, ... backup (session)?
A: If you have not changed the default settings in the Project Properties, Easy Creator Classic (EZ Classic) writes the both UDF and ISO (Joliet) file systems on the DVD discs. Unfortunately, probably due to the bug, EZ Classic hides a new files in UDF folders, but always shows them in ISO/Joliet ones. A solution is the following:
· Run CDRoller without any discs inserted.  
· Click the Preferences from the View menu and check on Read only ISO 9660 tracks box on the Browser tab in the Preferences dialog. Click the OK button to close the Preferences.  
· Insert the DVD into the drive and click the Refresh button in the Tool Bar. Only ISO/Joliet files and folders will be shown.  
· If the disc contains a several sessions, use the built-in Session Selector.  

Q: I am trying to double click on CD name in the List Window, but i get the message about "corrupted root folder". Is there any chance to read CD data?
A: The root folder on your CD seems to be unreadable (corrupted). At first, if your CD is a multisession disk, please try Session Selector in order to retrieve the data from previous session(s).

If your troubled UDF disc is write-once media (CD-R/DVD-R/DVD+R/DVD+R DL), try Search All VATs option in order to find and retrieve the files from the previous "backups". Often, this is useful if your disc was created and unfinalized by Adaptec (Roxio) DirectCD (Drag-To-Disc) software.

To find and recover the lost files on all UDF discs, we recommend you to use Scan UDF Disc option from the Tools menu.
Note. In case of multisession UDF CD, Scan UDF Disc searches for the files data in all sessions, excluding the current one, therefore some found files may be duplicated with the files retrieved by Session Selector.

If your disc is recorded with ISO file system, try to use the different settings under the ISO Reader tab in the Preferences dialog, and/or Identify Raw ISO Data option from the Tools menu.
Note. You should always click the Refresh button before a new settings will take effect.

Finally, please feel free to contact our Support Dept. via email at support@cdroller.com
to receive a technical assistance shortly.

Q: I have detected that CDRoller is not able to recognise (identify) my UDF disk inserted into CD-ROM drive (cd reader). However, if i insert the disk into CD-RW drive (cd writer), all files seem to be visible and i can also run Scan UDF Disc to look for the deleted (lost) files. Why?
A: Since UDF disks are written with so-called "packet-written" technology, some old CD-ROM drives can not recognise them at all. Also, if your CD is damaged, incorrectly closed or very poorly written you may also run into the problem that some readers can access to more CD data than others. In case of big problem, please try a few CD / DVD drives, ask your friends and/or colleagues to run CDRoller on their drives. You often have more success in cd data recovery, if you use CD(DVD)-RW recorders (cd writers) instead of CD(DVD)-ROM drives (cd readers).
