File Verification

File Verification is the process of verifying that a file has not been changed and/or that two files are identical, bit by bit. ViceVersa supports both types of file verification.

You can verify that files in a specified location have not changed by creating a snapshot of one or more folders at a given time and then re-comparing the folder content with the original snapshot at later time.

You can also verify that two locations have exactly the same files, bit by bit: ViceVersa will calculate the CRC of each file to make sure they are indeed identical. A very important and common task for people working with CD creation is the verification that the data mastered is the same as the original data. For this purpose ViceVersa offers a Cyclical Redundancy Check. With ViceVersa you can determine if even one byte of data differs.

Hi - when duplicating the contents of one full 120GB drive on to another empty 120GB with both the CRC file verification options ticked I notice that the drive controller statistics state that the source drive has read out 240GB of data with 0 written but the target drive shows 120GB written and ZERO read. Are you sure Vice Versa does file verification properly? From the statistics it looks like it's verifying source against source! (brian_vv AT brianoloughlin DOT com)

Hi, as a test, try to manually calculate the CRC of some files on target: in the comparison window select some target files and right click, then From the menu select "calculate CRC". thanks
