Sort files into folders
Pick a messy folder. Every file is moved into a subfolder by file type, extension or month. Free, and your files never leave your computer.
or drop a folder here
In this browser you get a sorted copy as a .zip file. The folder itself is not changed.
Your browser may ask you to confirm an "upload". Nothing is sent anywhere: the files are only read on your computer.
Free, no sign-up. Chrome and Edge sort the folder itself. Other browsers give you a sorted copy to download.
This browser cannot change files on your disk. You will get a sorted copy as a .zip file, and your original files stay as they are.

Questions
Are my files uploaded anywhere?
No. The sorting is done by your browser on your own disk. This site has no server that could receive files. More on the privacy page.
What do the three sorting options do?
File type makes folders such as Images, Documents and Videos. Extension makes one folder per extension, such as jpg, pdf and zip. Month makes folders such as 2026-11, based on when each file was last changed.
What does "Include subfolders" do?
Normally only the files directly in the folder are sorted and subfolders are left alone. With this option, files inside subfolders are sorted too. Programs and projects are never taken apart: app bundles, code repositories and folders such as node_modules are skipped.
What if two files have the same name?
Nothing is ever overwritten. The second file is renamed, for example report (1).pdf.
Can I undo it?
Yes. Open the same folder again and press Undo last sort. To make this possible, a small hidden file named .filesort-undo.json is kept in the folder.
Which browsers does it work in?
All current browsers. In Chrome and Edge on a computer, the folder itself is sorted and you can undo it. Firefox, Safari and phones do not let a website change files on your disk, so there you get a sorted copy of the folder as a .zip file to download, and your original files stay untouched.
Why can I not select my Downloads or Documents folder?
Chrome and Edge block websites from opening some system folders directly. Make a new folder inside it, move the files you want to sort into that folder, and select the new folder.
