GrpahVu Disk Space Analyzer is an application for exploring disk directory structure and finding large space-consuming folders and files. GrpahVu Disk Space Analyzer offers outstanding graphical representation of disk directory structure which is different from any other similar tool. Directory structures are presented as directed graphs with folders as nodes. The sizes of folder icons in a graph are proportionate to the sizes of folders they represent and users can clearly see which folders consume more disk space. Nodes are arranged automatically using one of the 3 graph layouts, and users can adjust node positions manually as well. Diagrams can be rotated or flipped horizontally or vertically. Disk scan is quick. Running disk scan can be paused at any time and users can view partial results, change scan priorities, hide folders if necessary then continue the paused scan. Users can free space by moving files and folders to the recycle bin or by deleting them permanently. User can quickly move folders to a new location on the same logical disk by editing graph edges. Users can also search for the files and folders and save results of the search in CSV-files. GraphVu Disk Space Analyzer 1.7 is available in 32-bit and 64-bit versions and can be downloaded from http://graphvu.com.
