Drop a folder or files here
Only file names and sizes are read. Your files stay on your device.
Find out which folders and files take up the most space. Choose a folder to compare its subfolders, browse files by extension, or inspect a list of the largest files. The size bars show each item’s share of the selected files.
Use the folder size analyzer before organizing a photo collection, reviewing downloaded videos, or deciding which archives to move elsewhere. Select a folder in the results to drill down, and use the path above the chart to return. The large-file view searches the full selected file list.
Export a CSV report with file paths, byte sizes, and extensions for your own records. This tool does not delete, rename, or change files. It measures selected file sizes, not the free space or exact disk allocation of your whole device.
It can analyze the folders you choose. Browser access is limited to your selection, so it cannot scan your entire device or report system free space.
The total adds the byte sizes of selected files. Disk allocation, hidden or inaccessible files, links, and filesystem compression can make the system’s storage figure different. Empty folders are not included.
No. Analysis uses only file names, folder paths, extensions, and sizes in your browser. The tool does not read file contents, upload files, or delete originals.
You can choose files on a phone. Folder selection and folder dragging depend on your browser and file picker; when unavailable, use Choose files. Each analysis supports up to 100,000 selected files.
