Large folders and files stand out as proportionally sized blocks in a treemap. SpaceSniffer scans a disk and turns its contents into a navigable view, so you can follow the largest areas to see what is using storage.
Scan a disk and follow the largest blocks
Start a scan to see an overview of the disk. Each block represents a file or folder, and larger blocks correspond to items taking up more space. Following the biggest blocks gives you a path from the overall view into the folders that account for substantial storage use.
Click a block once to reveal the selected folder’s contents within the map. Double-click a folder to expand it across the view, making its contents easier to inspect. Continue selecting folders to move deeper through the directory structure.
Filter the map by file details or tags
Enter a condition in the filter field to narrow the displayed results. SpaceSniffer supports file-type patterns, size and date conditions, and filters that can be combined.
- Type
*.jpgto show JPEG files, or|*.jpgto exclude them. - Use conditions such as
>1mbor>2yearsto filter by size or age. - Separate conditions with semicolons, as in
*.jpg;>1mb;<3months. - Tag files red, yellow, green, or blue while examining them; filter by a tag such as
:red, or use|:redto exclude red-tagged files.
Export a report of the scan
When you have narrowed the view to the files you want to document, use the embedded Export Module to create a text report. Its layout can be customized to suit the report you need.
