Xylem

Xylem 0.3.0: a fast disk space analyzer for Windows 10/11. It shows what fills your drive, what each thing is, and whether it's safe to delete.

New in 0.3

  • Fast compression, built in: right-click any folder → Compress…. Xylem now runs Windows' own file compression itself, on many files at once, instead of through compact.exe: about 15× faster at the new Fast level and 5× faster at Maximum in our tests (763 MB of mixed data). Files stay where they are and open as usual. It skips files that won't shrink, shows real progress with speed and time left, can be stopped, and Uncompress undoes it.
  • Similar folders (View menu): finds folders that look like copies of each other, and projects with similar names (project, project_v2, project - Copy), with how much each group takes.
  • Fixed: compressed files were counted as almost 0 bytes by the normal (no-admin) scan. Folders compressed with Windows' file compression (compact /EXE, CompactOS, Xylem's Compress) now show their real size on disk. Fast scan was not affected.
  • Fixed: "What changed" could compare a normal scan with a Fast scan as if your files had changed. Xylem now remembers how each scan was made and says so when the two differ; it also shows how far apart the scans were.
  • Clearer text about what needs admin rights and what Xylem can change; percentages no longer round a part up to 100%.

What it does

  • Scans a whole NTFS drive in about 1–2 seconds by reading its Master File Table, read-only, after the Windows admin prompt. Without admin it walks folders (no prompt).
  • Tree-table with a sunburst or treemap. Groups by location or by category (apps, media, dev stuff, AI & data, system, temp & caches…).
  • Explains known folders in plain English with a safety label, and locks Windows and system folders.
  • Deletes only to the Recycle Bin, after you confirm. It re-checks the item on disk first and warns about OneDrive folders, Git repositories and very large deletes. A deletion history is kept on your PC.
  • No network connections, no telemetry, no accounts.

Download

  • xylem-setup-0.3.0.exe: installer (recommended). Installs into Program Files, which protects the admin helper used by Fast scan. Includes an uninstaller (Settings → Apps).
  • xylem-0.3.0-portable.zip: no install. Unzip and run xylem.exe.
