Use image file to manage disc sectors.
This option forces the program to create and then use an own image file to manage the disc data (disc sectors). Here, image file means a combination of .tbl and .dat files having the same name before file extension. There are 2 big advantages of image file. First, some CD and DVDs can be "poor-written". Often, one CD/DVD drive can read only a part of such disc. If another CD/DVD drive can access to the bad sectors, CDRoller simply adds a new data to the image file created before. In other words, you get the best out of each and every drive you use. Second, if you intend to read the disc twice, you get much greater speed, having the image on your hard drive. Especially, when there are bad sectors on CD or DVD.
To activate this option, just check the box with the same name under CD/DVD Library tab in the Preferences dialog.
Further, when you insert the disc, you are prompted to type image file name that will be associated with this disc. We recommend to use friendly and unique name that simply tells about content of inserted disc. For example, 'My photo album 2010' or 'My trip to Canada in 2010'.
Note. It's a very hard task to check whether the inserted disc matches 100% to the created image or not. Particularly, for the "bad" CD or DVD, due to a lot of factors that contribute to this problem (CD/DVD media types and drives). Therefore, it is important that you always use a correct file name for the inserted disc. We also recommend to keep the created images in the safe place (separate folder). By default, the program places the images to the folder assigned in Directory for CD/DVD Images under CD/DVD Library tab in the Preferences dialog.
