How to find large files on Windows

Windows has two built-in ways to hunt big files, and both stop half-way. Here are all three options - what each shows and where it goes blind.

1. Explorer search: size filters

In any folder type size:gigantic into the search box - files over 4 GB. Other steps: size:huge (1-4 GB), size:large (128 MB-1 GB). You can sort results by size.

• Good: nothing to install, works everywhere.
• Blind spot: shows single files only. A folder of ten thousand 10 MB photos - 100 GB - never appears.
• Slow on a whole drive without the search index.

2. Settings - Storage

Settings > System > Storage shows usage by category: apps, temporary files, documents. Useful for one click - Temporary files - and that is about it: categories end exactly where the interesting part starts. "Other" holding 800 GB is a common sight, with no way to open it.

3. A disk map

A space analyzer answers the real question - what exactly takes the space - including folders that are big as a whole. On a ring map a 100 GB photo dump is a wide sector you cannot miss, whether it is one file or fifty thousand. In CleanMyWin file types carry icons (video, archives, installers), heavy items surface at the top of the list, and deletion goes to the Recycle Bin - reversible, long paths included.

Practical order

• One-off hunt for a giant ISO: Explorer with size:gigantic is enough.
• Cleaning temp files: Settings > Storage, one button.
• Disk is full and you do not know why: map it. A scan takes a minute and replaces an hour of guessing.
