Document Library View

The Document Library View is SharePoint Storage Explorer's per-site breakdown. After you have used the site overview to identify a large or fast-growing site, this view shows you which libraries inside that site are responsible.

Where to find it

Document Library View opens when you click any site in the Site Overview. You can also navigate directly: in the left navigation, click Sites, then double-click the site you want to inspect.

What the view shows

For the selected site, a table of every document library with columns for:

• Library name — the document library's display name.
• Library type — Documents (default), Form Library, Picture Library, Pages, Site Assets, etc.
• Storage (GB) — total bytes the library occupies.
• File count — total files in the library.
• Folder count — total folders.
• Largest file — quick-glance pointer to the single largest file in the library.
• Avg file size — useful for spotting libraries dominated by many small files vs few large ones.
• Versions storage — what version history contributes (site-level estimate by default; file-exact if you ran with file-level versions enabled).

The library marked Documents is usually the main user-facing library. Site Assets, Site Pages, Style Library, etc. are SharePoint system libraries that all sites have by default — they typically contribute very little storage unless something unusual is going on.

Common workflows

Find which library is the biggest

The default sort is Storage descending. The top row is usually the main Documents library; if a different library is at the top, investigate why.

Spot bloated system libraries

If Site Assets or Site Pages is contributing meaningful storage (say, more than 1 GB), the site has accumulated media or page content that is rarely user-visible. Worth a look — often the result of bulk-uploaded media that was never cleaned up.

Drill into a library's files

Double-click any library row. The view switches to the file browser for that library, showing the folder tree and per-file sizes.

Compare libraries across sites

Use reporting to export library-level data across all sites into a single CSV, then pivot in Excel.

When a library says zero storage

A library showing 0 GB is either empty or has not been scanned yet. Check the scan log in the bottom status bar to confirm the scan reached this library. If the scan completed but the library still shows zero, the library may be a special SharePoint-internal type that does not count toward tenant storage (rare).
