About web_link in SharePoint's API for getting a list of folder file lists.

Question

https://learn.microsoft.com/ja-jp/graph/api/driveitem-list-children?view=graph-rest-1.0&tabs=http

I would like to ask about the file property in the “GET /drives/{drive-id}/items/{item-id}/children” API response.

I would like to know all the files whose 'mimetype' in the file property is 'application/octet-stream'.

As far as I have tried, I believe that web links are applicable.

Hi @Ayase Morita

It seems that there is no support for using the API to directly get all files whose "mimetype" is "application/octet-stream". I suggest you use the Graph SDK locally to get the file set first and then filter the file set based on the file property.

    var files = await graphClient.Drives["{drive_id}"].Items["Root"].Children.GetAsync();

    foreach (var file in files.Value)
    {
        if (file.File != null && file.File.MimeType == "application/octet-stream")
        {
            Console.WriteLine(file);
        }
    }

Hope this helps.

Is there any mention in the official documentation of the type of file whose MimeType is application/octet-stream?
