This strange error is pretty perplexing and aggravating for the average Windows user, especially when you receive it when moving between drives and devices with ample free space.

Luckily, in ‘most’ cases, you can fix the problem without reformatting or reinstalling/repairing Windows.

How to Fix Error 0x800700DF Option 1: Change Your Device From Fat32 to NTFS.

I know the first thing we said was that there probably wouldn't be any formatting, however, If you are having this issue on an external device such as a hard drive, SD card, or USB stick, you will need to Reformat the device from Fat32 to NTFS. Thankfully it’s super easy to do and once done, you can upload files of any file size to the device. To do this, find your device under This PC, right-click on it, select Format then follow the prompts.

Important: Make sure you don’t have any data you want to keep on the device, as formatting to another storage type will erase all files.

If you happen to be using Microsoft SharePoint and are getting this error, you will need to check the maximum file size limit that is set. This can be done by going to Central Administration > Application Management, then Manage Web Applications. Here select SharePoint and choose General Settings.

Next, you will need to find out the Maximum Upload size and choose an option either equal to or higher than the Workbook Size in Excel Services. When you have done this, save the changes and exit, you should now be able to move your files without any problems.
