The full error reads:

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

This error normally happens when you try to download a file bigger than 50,000,000 bytes from a web folder. You may encounter this on Windows XP Service Pack 2 or later versions of Microsoft Windows. The problem happens because a security change was introduced in Windows XP Service Pack 2 that affects the WebDAV or Web Distributed Authoring and Versioning.

This security change guarantees that an unauthorized server cannot force a client computer into DoS attack or denial-of-service attack. That’s why when you download a file that is bigger than 50,000,000 bytes the client computer interprets this download as DoS attack and that’s why the download process stops.

To fix the problem, go to Folder copy error message when downloading a file then click the download button under “Windows XP SP2, Vista, or 7: Fix it for me” section. This downloads the “MicrosoftEasyFix55026.msi” file. Just run the file and follow the instructions.
