Inspect storage usage with O&O DiskCommander 5
O&O DiskCommander is the further development of O&O DiskStat, now available under a new name. Version 5 continues the disk-usage analysis workflow and adds tools for inspecting stored data and backups.
O&O DiskCommander 5 analyzes disks, partitions, and file systems and presents file and folder usage in structured lists. It helps you identify large collections and inspect stored data before deciding what to change.
Start with the drive or collection you want to understand. A large folder is not necessarily unwanted, and an analysis result should guide review rather than trigger automatic deletion.
Find where capacity is being used
Usage lists show which files and folders occupy storage. Review the largest items in the context of their location and purpose.
For example, distinguish an active project from an archive or a recovery copy. Confirm that a file is no longer needed, or that another verified copy exists, before removing or relocating it.
Review duplicate candidates deliberately
Duplicate search helps identify repeated files. Batch selection can span directories and partitions.
Inspect paths and your intended use before applying a group action. Identical copies may belong to separate projects or deliberate backups; retain those you still need instead of judging only by occupied space.
Inspect O&O DiskImage backups
Version 5 can load O&O DiskImage backups and inspect their file and folder structure without a full restore.
Use this to review what an image contains before planning recovery or auditing stored data. Browsing an image does not by itself verify every file or demonstrate that a complete system restore will succeed.
Use snapshots for later analysis
Snapshot analysis can show recorded drive information even when the original storage is disconnected. Analysis data can also be exported and imported.
Treat a saved analysis as a record of a particular moment. It does not necessarily reflect current contents and should not be treated as an independent backup of the files listed.
Review capacity warnings and analysis logs
A configurable storage threshold provides warnings, and logging helps you review analysis activity.
Choose a threshold around your normal usage and upcoming work. If a warning appears, inspect the relevant drive and data before deciding whether to archive files, adjust the workflow, or expand storage.
Choose backup and optimization tools separately
For creating system images and preparing recovery, see O&O DiskImage 23. For drive optimization, review O&O Defrag 32.
DiskCommander focuses on storage analysis and inspection. It should not be presented as deleted-file recovery, a repair for physical disk faults, or a guarantee that cleanup will make every application faster.
