Microsoft Surface File Size Limit with Explorer Fix

Today I ran into an issue on a win RT device when trying to download few folders from our SharePoint site using Explorer.

The Problem

This problem occurred when I used the ‘Open with Explorer’ interface in the Library Tools > Library pane to get the required folders, as I wanted to copy a few folders down from SharePoint onto my Surface.

One of the files failed to copy with the following error:

An unexpected error is keeping you from copying this folder. If you continue to receive this error, you can use the error code to search for help with this problem.

Error 0x800700DF: The file size exceeds the limit allowance and cannot be saved.

The file was only 90MB which seemed strange.

The Solution

Run REGEDIT as admin. One way of achieving this is to bring up the start menu type REGEDIT (type in full to make it appear in the apps search). Right click or pull down gesture to select it and click the run as admin option on the bottom app bar.

Then drill down into the following in REGEDIT

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

Then just edit the FileSizeLimitInBytes parameter to the desired amount (it offers a decimal value) and restart your surface.

You should now be able to use Explorer with SharePoint to grab those files worth having!
