  • Timestamp differences due to precision

    I didn't find this topic in the FAQ, so perhaps someone can provide a quick answer. There is a difference in resolution between XP/Vista/Win7 and earlier Windows timestamps. This difference is immediately noticeable with files stored on Flash Drives (and/or SD cards) vs. files on a later Win system, even though it's only a few seconds. Does B.C. have an option for ignoring this difference?

    Yes. You can set a timestamp tolerance, or you can use a Content Comparison to verify the files are content equal, and then use the Touch command to set the timestamp to also be equal.

    These KB articles may help:

    You can set timestamp tolerance in BC3 under the Folder Compare's Session menu -> Session Settings, Comparison tab. You can also set the Content Comparison here, then select Equal files (center column populates with an equal sign) and use the Right-click menu to find the Touch command.

    Let us know if you have any questions.

      There is a precision difference between the Fat32 (used by default on many USB drives and Windows 95, 98, and ME) and the NTFS file system used by XP, Vista, and Windows 7.

      Fat32 only stores timestamps to the nearest 2 seconds. This is why you can see a variance when comparing files on NTFS file systems with files on Fat32 file systems. BC2 and BC3 default to 2 seconds of tolerance for timestamp comparisons to ignore this difference.
