Drive Folder Size Viewer

About

Google Drive Folder Size

Due to limitations imposed by Google APIs, the extension will be reserved for 100 PRO users only; the Free Tier has been removed.

What does it do?
This Chrome extension improves Google Drive by showing the actual size of folders directly in the interface. By default, Google Drive only shows "-" for folder size, making it impossible to tell how much storage space they are taking up.
