Trusted Files
Files added to the Trusted Files list are automatically given Defense+ trusted status. If an executable is unknown to the Defense+ safe list then, ordinarily, it and all its active components generate Defense+ alerts when they run. Of course, you could choose the 'Treat this as a Trusted Application' option at the alert but it is often more convenient to classify entire directories of files as 'Trusted Files'.
CIS allows you to define a personal safe list of files to complement the default Comodo safe list.
By adding executables to this list (including sub folders containing many components) you can reduce the amount of alerts that Defense+ generates whilst maintaining a higher level of Defense+ security. This is particularly useful for developers that are creating new applications that, by their nature, are as yet unknown to the Comodo safe list. Files can be transferred into this module by clicking the 'Move to' button in the 'Unrecognized Files' area.

Adding files to Trusted Files list
CIS allows you to add files and executables to the list of Trusted Files so that those files will be given Trusted status. For the files added manually, it generates a hash or a digest of the file using a pre-defined algorithm and saves in its database. On access to any file, its digest is created instantly and compared against the list of stored hashes to decide on whether the file has 'Trusted' status. By this way, even if the file name is changed later, it will retain its Trusted status as the hash remains same. However you can also add files by their file names, but if you happen to change the file name later, it looses its 'Trusted' status.
