PurgeCore vs WinDirStat: Which One Should You Use?

2026 · 5 min read

WinDirStat has been the classic answer to "where did my disk space go" since 2003: point it at a drive, get a colorful treemap of every file. It's free, open source, and still actively maintained. Here's how it compares.

What WinDirStat does that PurgeCore doesn't

• A treemap visualization. Every file drawn as a rectangle sized to its footprint, colored by file type. It's a genuinely fast way to spot one enormous file or folder at a glance, and PurgeCore doesn't have an equivalent view, it uses sorted lists instead.
• A file-extension breakdown showing exactly how much space each file type consumes across the whole scan.
• Two decades of maintenance and a large, established user base, including plenty of IT professionals who reach for it specifically because it's simple and does one job.
• Elevated scanning support for reaching protected system folders a standard user account can't read.

Where PurgeCore takes a different approach

• Cleanup features beyond "find and delete manually." WinDirStat lets you delete, move, or compress files from its interface, but it doesn't find duplicates, clean browser data, manage startup programs, or touch the Recycle Bin and Temp folder as dedicated features. PurgeCore builds all of that around the initial scan.
• Guardrails on deletion. WinDirStat's delete action is a direct file operation, effective, but with no built-in risk rating or Recycle Bin safety net baked into the workflow the way PurgeCore's is.
• A dashboard and category breakdown as the first screen, rather than jumping straight into the file tree.
• Duplicate detection, matched by actual file content rather than name or size, something WinDirStat doesn't do at all.

Two tools built around different jobs

WinDirStat answers one question extremely well: where, visually, is my disk space going. It doesn't try to be a full cleanup suite, and for people who just want that answer and are comfortable deleting things themselves afterward, it remains a solid, no-nonsense choice. PurgeCore starts from a similar question but is built to also act on the answer, with safety rails around anything that deletes something.

Bottom line

If a treemap is the specific view you want, or you're an IT professional who just needs a fast, no-frills way to see where space went on a machine you're troubleshooting, WinDirStat still does that job well. If you want disk analysis plus duplicate detection, browser cleanup, RAM and startup management, and safety-first deletion in one app, that's the broader scope PurgeCore covers.
