Hey Product Hunt 👋

I’m Gabriel, a solo developer. I build my own apps in the evenings after my day job.

Why I built DiskSense: my drive kept filling up, and Windows Storage settings could only tell me a huge chunk of it was “Other”. The tools I tried showed me a pretty map of folders but couldn’t tell me why things got big, what moved, or what was safe to look at first. So I built the tool I wanted.

What it does:

Names every gigabyte. Every drive, every folder, biggest first, so you can see what “Other” actually is.
Shows what each app really uses. Windows might say an app is 3 GB. DiskSense adds up its install, data and cache folders and can find 58 GB.
Finds duplicates across all your drives.
Remembers where files went. It keeps 90 days of renames, moves and deletes, and catches up on changes made while it was closed. Search a file’s old name to find it under its new one.
Searches as you type, across hundreds of thousands of files.
Answers questions through your AI app. It has a built-in MCP server, so Claude, ChatGPT, Cursor and others can answer “why is my drive full?” They only see names, sizes and dates, never what’s inside your files, and you switch it on per app.

It only reads. DiskSense never deletes anything on its own; you decide what goes.

There’s a free 3-day trial at disksense.coolsoftware.io.

What feedback would help most:

Did it find something on your drive that surprised you?
What’s the first thing you’d want it to tell you that it doesn’t yet?

I’ll be here all day replying to every comment. Thanks for checking it out 🙏
