StorageFox

StorageFox helps you understand and reclaim disk space. Scan any folder and explore its contents with interactive treemaps and sortable tables, so large files and space-hungry folders are easy to find.

Disk space can disappear a little at a time until finding what is using it becomes a job of its own. StorageFox scans any folder you choose and turns thousands of files into a view you can understand at a glance.

Use the interactive treemap to spot the files and folders taking up the most room, or switch to a sortable table for a more detailed view. Navigate through the folder hierarchy without losing the context of the original scan.

Filter results by name, size, creation date, or modification date. Switch between folder, file extension, creation date, and modification date views to investigate storage from the angle that best answers your question.

When a scan is worth keeping, save it as a StorageFox snapshot in the .fvi format. Open it later to continue exploring without scanning the folder again.
