Folderscope is a free program 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.
Features:
* Get a quick and complete overview of the hierachical structure and content of a new folder you have received.
* Find the most recently modified files anywhere in a folder hierarchy of documents.
* Find the files and folders taking up the most space on your hard drive, and move them to a different drive.
* Find duplicate files (files with identical content) in your documents folder and delete them.
* Reliably copy the entire content of one external hard drive to another.
* Backup the files from your main hard drive to an external drive.
* Search for files of a paticular name (or partial path) quickly in a big hierarchy of files.
* Extract files of a particular type (for example image files) out of a hierarchy and move them to a different root folder.
