How It Works
Connect to your Google Drive folder
Simply provide access to the folder you want to analyze. The tool works entirely in your browser using Google's official Drive API.
Scan all files and nested folders
The tool recursively traverses through the folder structure, discovering all files within nested subfolders at any depth level.
Calculate total size
Each file's size is fetched and added together to give you the complete folder size, including all subdirectories and their contents.
The entire process happens in your browser - no data is sent to our servers. You get real-time progress updates as the tool calculates your folder size.
Why Google Drive Doesn't Show Folder Sizes
Folders are just metadata in Google Drive
Unlike traditional file systems, Google Drive treats folders as special files with a "folder" type. They don't actually contain files in the conventional sense.
Files reference their parent folders
Each file in Google Drive has a "parent" property that points to its containing folder. This parent-child relationship is stored as metadata on the file itself, not within the folder.
This architecture makes calculating folder sizes computationally expensive, which is why Google Drive doesn't display them by default. Our tool iterates through all files to calculate the total size for you.
