SharePoint 2010 File Size Upload Limits – The Essential Mix

January 25, 2013

​Clearly there are a lot of articles & posts on net regarding increasing File Size Upload limits in SharePoint. Unfortunately I couldn’t find any one that was comprehensive enough to include ALL the tweaks you need to consider to accomplish the goal, on both the SharePoint and IIS level. So here’s mine:

Errors Encountered:
– “Page cannot be displayed” when uploading large files
– Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved
– The specified file is larger than the maximum supported file size

    Thank You for such a well written article.

    It is of real help, as I too couldn’t find a single source (including MSDN Support) where proper steps are noted for this requirement of increasing file upload size.

      There’s no way to proactively determine the file upload size and throw an alert/error – as that would require access to the users file system, which is simply not possible in regular HTTP uploads. Using Flash or Silverlight, it is possible to access details of the file to be uploaded from the users desktop. Therefore there is a possibility of writing a custom Application page for SharePoint 2010 that has an upload control that could say “Hey, this file you’re going to upload is really much too large for our system to handle”. It would not be an exact science, as upload time is a combination of bandwidth and latency.

      Otherwise, your users will most definitely get an error/alert if one of the default SharePoint timeout limits is hit.

    HI, I understand that the settings must be increased to allow for large file upload, however can I use PowerShell to import a file that exceeds the default upload amount without error? simply stated, not change the default amount of the web app and upload the larger file using PowerShell to bypass the threshold?


    • Keith Tuomi says:

      Hi Alysa,

      No matter the method used to transfer the file in it’s going to have to meet the SharePoint object model and IIS settings- PowerShell, although being powerful as it’s name implies, can’t let you overcome the settings described in this post, unless you somehow used it temporarily increased the limits. That would mean configuring all of the limitations described in this post with PS, which i’m not sure is even possible.

    We have an issue where we need to upload videos more than 500 MB size and want to show in sharepoint pages. We want to upload the videos in a shared folder. Is it possible?

    • Keith Tuomi says:

      Sure, as indicated on this post the max upload size per file is 2GB. You could provide the WebDAV (Windows Explorer View of a SharePoint library) link to your users and they would be uploading files via the shared folder.

      The general way that you normally interface with a WebDav enabled server is via My Network Places
      •Open Windows Exploer
      •Select “My Network Places” on the left pane under “Other Places”
      •Click on “Add a Network Place”
      •The “Add Network Place” wizard will then start, click on Next
      •Select “Choose another network location” and click next
      •Type in your path to your document library such as “ Documents” and click next
      •Give it a name and click next
      •Click finish

      Your Network Place will then be displayed in an explorer window. This window however does use the full path that you specified as the location/address in Explorer ( \www.mywebsite.comShared Documents ). Wouldn’t it be nicer to map it to a drive letter such as X: so that any application can save directly into the Sharepoint document library?

      Well you can if you follow these steps instead.

      From Windows Explorer
      •Open Windows Explorer
      •Select Tools / Map Network Drive
      •Select your drive letter
      •Under Folder : enter your url to your document library such as “ Documents“
      •If you want to connect as a specific user click “Connect using a different name” and enter the other user credentials.
      •Click on Finish

      From a CMD.EXE Prompt
      •Start a command prompt (type cmd.exe into the Start-Run option)
      •Type in the following:
      net use x: “ Documents” /user:DOMAINLOGIN PASSWORD

      •You will now have a drive letter mapped to the Shared Documents folder.

      Note: You will need to enable the WebClient service if it is not running already
