Freespace scans your whole drive, finds temp files, caches, Windows Update downloads, logs and large files, tells you what is safe to delete, and removes only what you tick.
Free and open source. Windows 10 and 11, 64-bit.
No guessing from folder names alone. Each candidate is checked against what is around it before you ever see it.
Walks the drive in parallel, without following links.
target only counts next to Cargo.toml, bin next to a .csproj.
Is there a lockfile? Is it committed to git? Is the path protected?
Safe, Review or Do not delete, with a reason and a restore command.
Nothing goes until you tick and confirm. Each delete is re-checked as it runs.
Temp files, browser caches, update downloads, log files and crash dumps from every corner of the drive, grouped by category with their total size.
These grow quietly across every project you touch. Packages download again the next time a project needs them. Green is Safe; amber is Review, because the next build has more to fetch.
Downloaded updates in SoftwareDistribution\Download and the Delivery Optimization cache. Windows fetches again whatever it still needs.
Chrome, Edge, Brave, Firefox and Opera, plus VS Code, Cursor, Discord, Slack, Teams, Spotify and JetBrains IDEs. Passwords, history and cookies are not touched.
Finds *.log files outside system folders and tells real logs from database journals that only look like logs, because deleting those corrupts data. Also blue-screen dumps and Windows error reports.
Yours and Windows'. Only the contents go, and files still in use are skipped.
SafeDirectX, NVIDIA and AMD shader caches, and Explorer's thumbnails and icons. Rebuilt on their own.
SafeOlder app versions kept after an update, downloaded installers and extracted NVIDIA and AMD drivers.
SafeFiles you already deleted, still taking up the space.
SafeSetup and servicing logs, only useful when troubleshooting Windows.
ReviewWindows.old and upgrade files. Deleting them removes the option to roll back.
Previews everything Safe plus Windows rollback leftovers, then runs it or just ticks it for you to review. Optional extras: DISM component store cleanup, and turning off hibernation to remove hiberfil.sys.
Delete node_modules and build output safely, and find the gigabytes your projects can rebuild.
Node.js, Rust, .NET, Python, Go, Java, Flutter and PHP. Monorepos count once, and one click ticks everything safe in dormant projects.
A scan can reach repos you do not trust, and a repo's config can make git status run programs. So Freespace only reads the files.
Browse folders biggest-first beside a treemap, and tick any folder that is not protected.
Old ISOs, virtual disks and archives, wherever they hide.
Run the app's own uninstaller, then clear what it left behind, or reset it to fresh.
Close the window and it stays in the tray. It repeats your last scan on the schedule you pick, from 30 minutes to a day, and waits while you are working. A rescan only reads the disk.
Send deletions to the Recycle Bin instead, and get a report of what was removed, what was skipped, and how much came back.
Rebuilt or downloaded again. Fine to delete.
node_modules + lockfile, target, .next, npm cache, Windows Update downloads
Probably fine, but look first.
node_modules without a lockfile, committed dist, .venv, large files, app leftovers
Protected. These rows cannot be ticked.
Windows, Program Files, profile folders, every .git
Nothing about your files leaves your PC.
Scan your drive with Freespace, review what it finds by category, and tick what to remove. Temp files, browser caches, Windows Update downloads, package manager caches and build output are good places to start. Every item is labelled, and nothing is deleted until you confirm.
The Space usage page lists folders biggest-first beside a treemap, so you can open any folder and see where the space went. The Large files page finds files of 512 MB or more, such as old ISOs, virtual disks and archives.
Yes, if the project has a lockfile, because npm ci, pnpm install or yarn install restores the exact versions. Freespace looks for the lockfile first. Without one, node_modules is marked Review, since a reinstall may pick different versions.
Yes. Package manager caches hold downloads, which come back the next time a project needs them. Freespace marks larger stores such as Gradle, Maven, NuGet packages and the pnpm store as Review, because your next build has more to fetch.
Yes. Downloaded updates in SoftwareDistribution\Download can be deleted, and Windows downloads again whatever it still needs. Cleaning this folder needs administrator rights, which Freespace asks for when it starts.
Usually. Old log files and crash dumps are only useful for debugging. Freespace marks logs written in the last 7 days as Review, and skips database journals that only look like logs, because deleting those corrupts data.
No. Freespace only removes cache folders from Chrome, Edge, Brave, Firefox and Opera. Passwords, history and cookies are not touched. Close the browser first so its files are not in use.
Yes, if you choose the Recycle Bin option in the confirm dialog, which moves items there instead of deleting them permanently. The space only comes back once you empty the bin.
Yes. Freespace is free and open source under the MIT license, with no account, no ads and no telemetry. It runs on Windows 10 and 11, 64-bit.
Free and open source. Scan first and delete nothing if you like.
