Is there any REST api / any approach to get the size of list and library in a site collection using client object model.? I know we have SPSite.StorageManagementInformation but this is can be used in SSOM only, do we have anything similar to that in CSOM. For document library, I don't want to loop through all the documents in that library and get item.File.length as shown below, as I have more than 2000 site collection, if I use the below loop, then it would take a decade to get the size of SharePoint library.

if (item.File != null)
{
 listSize += item.File.Length;
}

but the above code can not be used for SharePoint list, in this case how to get the size of a SharePoint list.

I don't think so, because Documents are not stored a filesystem but in (rows in) a Database. These rows are chunks of data, not bytes.

So the size of a Document is metadata (written on file upload/change), not space occupied in the database.

That means total size of a Library can only be found with a loop

Alternatively you could add your own administration on every Document change. Maybe a workflow that keeps track of file-sizes.

You can get total TotalFileStreamSize and TotalSize of a document library from StorageMetrics. Make a GET request to following end-point.

/_api/web/getFolderByServerRelativeUrl('relative path of library')?$select=StorageMetrics&$expand=StorageMetrics

PS: Tested in SharePoint online and it works for libraries

Sample Response

{
    "d": {
        "__metadata": {
            "id": "https://xxx.sharepoint.com/sites/sm/_api/Web/GetFolderByServerRelativeUrl('/sites/sm/SiteAssets')",
            "uri": "https://xxx.sharepoint.com/sites/sm/_api/Web/GetFolderByServerRelativeUrl('/sites/sm/SiteAssets')",
            "type": "SP.Folder"
        },
        "StorageMetrics": {
            "__metadata": {
                "id": "https://xxx.sharepoint.com/sites/sm/_api/Web/GetFolderByServerRelativeUrl('/sites/sm/SiteAssets')/StorageMetrics",
                "uri": "https://xxx.sharepoint.com/sites/sm/_api/Web/GetFolderByServerRelativeUrl('/sites/sm/SiteAssets')/StorageMetrics",
                "type": "SP.StorageMetrics"
            },
            "LastModified": "2016-11-16T09:15:07Z",
            "TotalFileCount": "6",
            "TotalFileStreamSize": "292912",
            "TotalSize": "348099"
        }
    }
}

TotalFileStreamSize is the actual size of your library in bytes. You can using my REST Client for testing/exploring.

  • the API which you mentioned doesn't return anything. I'm not using SharePoint online, it's enterprise which I'm trying to connect from a console app using csom – Karthik Jaganathan Nov 21 '16 at 12:41
  • It only returns the last modified of a list, not the other information's. – Karthik Jaganathan Nov 21 '16 at 12:47
  • okay. Me tested on SharePoint Online. Right now I can not test in On-Premise. :( – Atish Dipongkor - MVP Nov 21 '16 at 12:50

I don't know if this will help you but with PowerShell you can get data from storage metric.

$Site = Get-SPsite "http://your.sharepoint.site"     
$DataTable = $Site.StorageManagementInformation(2, 0x11, 0, 0)     
foreach($Row in $DataTable.Rows)
{
    if ($Row.Title -eq "Shared Documents" -and $Row.Directory -eq "team")
    {
        $LibrarySize = [Math]::Round(($Row.Size/1MB), 2)
        Write-Host $LibrarySize "MB"
    }
}

This could be an approach to your problem.
