Does SharePoint have metadata for file size and checksum via REST?

Retrieving Metadata

I can retrieve and item's information using:


I can see many metadata information, including created and modified dates. That said, I haven't seen any metadata item that shows the file's size. Is the information available?

End Goal

What I would really like is to retrieve all the metadata for all files in a specific folder, including the file size and checksum.

My current method involves downloading the file and obtaining the file size locally, which is more resource intensive than I'd like -- I'd especially like to avoid downloading large files.

Likewise, is there a checksum that could be used to compare local files to those stored in SharePoint?

Make a GET request using this It will show response in JSON format.

You can use the below rest Api to make a request.

/_api/web/getfilebyserverrelativeurl('/Library Name/DocumentName.doc')/Length?@target='http://YourSiteUrl/'

And you should be able to see the response in JSON format like this with the Length of the file: enter image description here

OR Using Ajax call and you can get the Length and convert it to Human readable format:

    url: "/_api/web/getfilebyserverrelativeurl('/LibraryName/DocumentName.doc')/Length?@target=http://YourSiteUrl/", //THE ENDPOINT
    method: "GET",
    headers: {
        "Accept": "application/json; odata=verbose"
    success: function(data) {


        function getFileSize(size) {
            var i = Math.floor( Math.log(size) / Math.log(1024) );
            return ( size / Math.pow(1024, i) ).toFixed(2) * 1 + ' ' + ['B', 'kB', 'MB', 'GB', 'TB'][i];


    error: function(data) {
        failure(data); // Do something with the error


You can see the file size in kb in the Console log:

enter image description here


You can use below rest api to get file size without downloading file...


You will get one node with below name which will return file size....

<d:vti_x005f_filesize m:type="Edm.Int32">1003</d:vti_x005f_filesize>

Not sure about checksum but I see streamhash as one of property...

  • Are these properties documented anywhere? That's a lazy question, since I haven't searched yet (but plan to). Also, do do you know of any way to do this for multiple files in a folder? I want to reduce HTTP requests if I can. -- Otherwise, this is perfect and will most likely be my accepted answer once I give it a try!

  • Unfortunately, it didn't work -- I was able to getFolderByServerRelativeUrl('/path')/Properties, but not for the file

  • But according to the MSDN, there's a "length" property, which is the file size: msdn.microsoft.com/en-us/library/office/…

  • It should work for file also, I have given a try and then posted above answer xml nodes which in answer represent actual file size, what are you getting when trying ? You can direct put above in any browser and you should get xml response... Commented Nov 10, 2016 at 4:00
  • Just what I mentioned the getFileBy.../Properties doesn't display the vti...filesize, but does include a Length; whereas the getFolderBy.../Properties does have the filesize. I don't think that's a limitation of my implementation, since the help docs seem to confirm what I'm seeing.
