Folderscope

Folderscope is a free software utility for analyzing and reorganizing folders of any size. It is designed to work efficiently even with extremely large folders, and has been tested on a folder containing 800,000 files and 400 gigabytes of data. Folderscope presents the user a flat sortable list of all the files contained within a folder (including the files in any of its subfolders). Files and subfolders can then be browsed and marked in a variety of ways. Marked files can be copied, moved or deleted all-at-once. All changes are added to a scrollable Pending Changes list for inspectation before being committed.
