Microsoft 365 Web Storage Quota Badge

WHAT IT DOES

Microsoft 365 Web Storage Quota Badge reads OneDrive and SharePoint storage usage and quota from your Microsoft 365 account and displays a floating storage quota badge showing used/total storage, percentage used, and a progress bar. The badge shows the amount of storage used and total available, with color coding—blue for normal, yellow for high (over 70%), and red for critical (over 90%). A breakdown shows usage by file type when available. The extension tracks storage usage history per month, storing each usage record with a timestamp. When storage usage exceeds 85%, a desktop notification is triggered. The panel displays your current month's storage history and changes over time.

WHERE IT RUNS

This extension works on Microsoft 365 pages at office.com, onedrive.com, and sharepoint.com, specifically on account pages where storage usage and quota are displayed. It runs on the main account page, the OneDrive storage page, the SharePoint storage page, and any page displaying storage information. The extension operates entirely within your browser and does not access Microsoft's servers directly—it reads only what is visible on the page you are viewing. It works alongside the free BotGentz extension, which provides the necessary scripting environment.

HOW TO USE

Install the extension, then navigate to office.com, onedrive.com, or sharepoint.com and log in to your account. The extension automatically creates a floating storage quota badge on the page. Click the extension's icon in your browser toolbar to open the settings panel. Use the "Show Overlay" / "Hide Overlay" button to toggle the badge visibility. The badge shows your storage usage, progress bar, and file type breakdown. Use the "Refresh" button to manually update the badge with the latest storage information. The "Show file type breakdown" toggle controls whether file type details appear. The "Storage limit notifications" toggle controls desktop notifications when usage exceeds 85%. Adjust the overlay transparency using the opacity dropdown (70%, 82%, 92%, or 100%). Drag the badge by clicking and holding anywhere inside it. Resize it by dragging the bottom-right corner. Close the badge with the × button.

STORAGE USAGE EXTRACTION WITH MULTI-UNIT PARSING AND HISTORY TRACKING

Unlike simple storage display tools, this extension uses a multi-selector extraction engine to find storage usage, quota, and breakdown from Microsoft's varying page structures. It searches for usage display using multiple selector patterns (.storage-usage, .quota-usage, .used-storage) and falls back to text parsing. The storage parser handles multiple units (GB, TB, MB, KB) and normalizes all values to GB for consistent display, supporting formats like "12.5 GB / 50 GB" and single value formats. File type breakdown is extracted from breakdown or file-type sections, capturing labels and sizes. Monthly storage history is stored as a key-value object where keys are year-month strings and values are arrays of storage records with timestamps, limited to 20 entries per month. Storage limit notifications trigger when usage exceeds 85%, with a once-per-day cooldown.

THE PANEL

The panel supports drag-to-move anywhere on the page. It remembers its position per site, so it stays where you placed it on office.com, onedrive.com, or sharepoint.com. Click the panel header to collapse it down to just the minimized bubble, or click the expand handle to show the full panel. The panel can be resized by dragging the bottom-right corner. Press the Escape key to close the expanded panel and return to the minimized state. All panel settings, including position, size, collapsed state, opacity, breakdown visibility, notification preference, and monthly storage history, are saved per site and persist across browsing sessions.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and active, as it provides the underlying DOM injection and script execution environment. Microsoft's websites change periodically, and storage element structures, class names, and page layouts may be updated. When that happens, the extension may stop detecting storage data until an update is released. The extension stores your overlay position, size, opacity, visibility, breakdown preference, notification preference, and monthly storage history locally in your browser's storage using GM_setValue. Storage history is stored as a key-value object where keys are year-month strings and values are arrays of storage records. The storage usage displayed is read from the page—the extension does not access Microsoft's internal storage data. Always verify with Microsoft directly for the most accurate storage information. No data is ever sent to any server, and no personal information is collected. You can clear all stored settings at any time by clearing your browser data for office.com, onedrive.com, or sharepoint.com.
