When using the ItemCount function on the / folder, the count is 0.

The result of GET /_api/web/GetFolderByServerRelativeUrl('/')/ItemCount is:

  "d": {
    "ItemCount": 0

But the content is actually not empty as it contains all the system related files as well as the user created libraries.

I can't seem to find anything about this on google or the sharepoint api documentation.

Is there another way to get it? I know it's possible to count items in a library using the list functions, but a folder is not list.

    Are you aware of that GetFolderByServerRelativeUrl returns items only and only if they are located at the very level specified inside the ('<level>')? That means that your query would return the ItemCount of items at the /-level of your hierarchy, but not below that level. – moe May 30 '17 at 13:33
  • good find, moe! – Mike May 30 '17 at 15:28
  • @moe Thanks for the answer! Yes, but there are items at the /-level, this is precisely what I'm trying to access. There are in reality 13 folders and 2 files that are returned at that level when not using the ItemCount function. That's why I'm confused – Ganitzsh May 31 '17 at 7:34

I think you are facing a similar restriction as in this existing question: Getting an ItemCount with filtering in SP2013 using REST api.

To quote Vadim:

"The ItemCount function could be applied to List resource [...] but not to ListItemCollection resource".

This same restriction would apply to FileCollection resource and FolderCollection resource, which - if I'm correct - the / level would represent either of.

ItemCount's description is the following:

Gets a value that specifies the count of items in the list folder.

This would mean, that a sub-directory (i.e. a type of SP.Folder) would be applicable


Note, that by using GetFolderByServerRelativeUrl can be returned items, so e.g. Folders would be excluded.

  • Thanks for the link. I think / is indeed a Collection, it works with subfolders so I guess you're right. It is confirmed as well when trying to use the ListItemAllFields on GetFolderByServerRelativeUrl('/') which is giving the following error: The object specified does not belong to a list.. So far, using ItemCount on other folders is giving the correct amount of files AND folders. – Ganitzsh May 31 '17 at 9:26
