From Flexense:
FlexTk is an advanced file management toolkit allowing one to search and classify files, scan file systems and apply rule-based, file organizing or data migration policies, analyze storage utilization, copy large amounts of files in a fault-tolerant way, identify duplicate files and free-up wasted storage space. All file operations are available through a centralized and easy-to-use GUI application with a built-in file navigator allowing one to execute any required command in a single mouse click.
New in this version: FlexTk for Linux-based operating systems. Also advanced, configurable fault-tolerance options.
