Filter by extension, size range, date modified, category, or filename
Export results to CSV for reporting or audit trails

How it works

Click "Choose Folder" and select any local directory
All file sizes and dates are read recursively in your browser
Metrics computed: size, % of total, % of parent, last modified
Expand/collapse folders in tree view, or switch to Treemap
All columns are sortable; toggle visibility to customize the view
Double-click any folder row to expand all its children at once
