Your C: drive is full again.
SizeScope knows why.
Point it at any drive or folder and it draws a living map of your disk — see every file and folder by size, watch what grew since last week, and clean up junk safely.
Windows 10/11 · no admin needed · no account · nothing uploaded
A map of your disk
Every file and folder becomes a colored block sized by the space it takes. The 8 GB game folder and the 12 KB text file are obvious at a glance — click any block to zoom deeper.
Growth tracking
SizeScope remembers previous scans and shows exactly which folders grew or shrank — the answer to “why is my disk suddenly full?”
Biggest files, instantly
A sorted list of the 100 largest files in your scan — the fastest way to find that forgotten 20 GB download.
Safe cleanup
One-click cleanup for temp files, Windows temp, and the Recycle Bin — with live sizes measured before you decide. Skips junctions and system links.
Scan, see, clean
Pick a drive or folder
Your whole C: drive, Downloads, an external disk — hundreds of thousands of files scanned in about a minute.
