Storage Analyzer
Select files or a folder and see how much space they use. Analysis stays in your browser.
On a PC you can select an entire folder. On mobile, select the files you want to analyse. The browser does not allow a website to read all your storage without an explicit user action.
What this tool does
Select the files or folders you want to inspect to calculate their combined size. The browser only sees items you explicitly choose in the file picker; this tool does not scan the whole drive or reveal files you have not selected.
How to use it
Enter the values requested by the calculator and check the result together with the notes shown below it.
Practical example
Use a realistic example from your own setup to compare scenarios. The result is a reference, not a replacement for manufacturer specifications.
How to interpret the result
Treat the result as an estimate whenever real-world factors are not available to the browser. For hardware, network or safety decisions, verify the relevant technical specifications.
Frequently asked questions
Are my files uploaded?
No. The tool reads the names and sizes of the files you select directly in your browser, without sending them to any server.
Why does the list show only 200 files?
The list is limited to 200 rows so the page stays smooth when you choose large folders.
