RE: questions on FILE_INTERNAL_INFORMATION.IndexNumber <LYR1318-2122-2000.04.21-12.11.27--rnagar#ntc

questions on FILE_INTERNAL_INFORMATION.IndexNumberThe IndexNumber is
guaranteed unique for files as well as directories on NTFS
volumes on a per-volume basis. However, if you examine the FASTFAT code
provided with the IFS Kit, you will notice that the index number might
indeed
change for a file especially when the file is renamed.

On NTFS and FASTFAT volumes, you should also be monitoring for file delete
requests.

Hello,
Can anyone tell me if the IndexNumber identifier returned for a
FileInternalInformation file information query is:

a) guaranteed to be unique on a given volume for both files and
directories
b) can a file or directories IndexNumber change over time? If so, what
circumstances will change it.

Thanks,
Joel
