SpaceScan Files

First release.

Finds what is filling up a Windows drive. On NTFS it reads the Master File Table directly, so a whole drive — a 10 TB one included — is mapped in seconds.

• Folder tree with size bars, percentages and file counts
• File types, and the same totals grouped into categories
• Largest files, and search by name, size or age
• Duplicate finder with the space you would get back
• Compare a scan with an earlier one; every scan is stored automatically
• Delete, copy and move from the results, several items at once
• HTML and CSV export, exclusion rules, and a command line for scheduled reports
• Right-click integration for Explorer and File Labs

Per-user installer, no UAC prompt. Reading the MFT needs administrator rights, which the app asks for only when a scan needs them.
