Large Folder Analyzer
See which subfolders inside a large folder are actually taking up the most space — ranked and visualized, so you know exactly where to look.
How to use Large Folder Analyzer
- Start by providing the required input: Select the folder to analyze.
- No additional settings need to be configured.
- This tool has no separate run button; its results update as you add or change the input.
- Review the result or preview on the page and confirm it matches your input before using or sharing it.
Finding which subfolder is actually the problem
"This whole project folder is huge" is rarely true evenly — usually one or two subfolders account for most of the size while the rest are small. Breaking total size down by top-level subfolder, ranked and visualized, points directly at where to focus instead of guessing.
Subfolder-level versus file-level analysis
This deliberately stays at the subfolder level rather than listing individual files — useful for a first-pass "where is the bulk of this" question before drilling into a specific subfolder with a file-level tool like Large File Finder.
What counts as a "top-level" subfolder?
Folders directly inside the one you selected — files sitting directly in the selected folder (not in any subfolder) are grouped separately as "(root files)".
Can I drill into a specific subfolder afterward?
Not directly from this tool — re-select that specific subfolder and run Large File Finder or File Size Analyzer on it for a file-level breakdown.
Does this read file contents?
No — only file sizes and paths are read, so this stays fast even on large folders.
