O&O DiskCommander is the successor to the O&O DiskStat product range and shows you exactly where your storage capacity is going. It visualizes drive usage in clear lists and charts, identifies the largest space-consuming files and folders, and detects duplicate files so you can remove redundant data. It can open and analyze O&O DiskImage backups directly, without restoring them first. Batch operations let you move, copy, or delete files across drive boundaries, with optional logging of every operation. It works with local hard drives, external media, and network locations, supporting NTFS and FAT file systems, and can warn you when storage thresholds are reached.
