Abstract
A method (and corresponding system and computer program product) detects modified files and/or directories in a storage device. The method builds a file-sector coordination table for files in the storage device before relinquishing access control of the storage device to a host computer. The method passively monitors write transactions in the storage device from the host computer. The method identifies sectors affected by the monitored write transactions and stores in a sector list. The method regains access control of the storage device from the host computer and builds a list of modified files by intersecting the sector list with the file-sector coordination table. The method may optionally share the list of modified files with related applications.
