SharePoint Explorer view - File size exceeds the limit

While trying to copy large files in the explorer view of SharePoint document library, you may get an error message

This error message is not due to SharePoint setting itself. In this particular case the user was accessing the file from SharePoint online where is limit of the file size is 15 GB. However due to the web client setting on the users machine, he was getting this error message.

If the user tries to download the same file using SharePoint web UI he does not face any problem.

To increase the limit on machine for web client you can:

1. Open registry editor (click start,-> Run -> type regedit in the run window and enter)
2. Navigate to following Registry folder - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
3. Change the value for the key "FileSizeLimitInBytes" to whatever you need to
4. Note that there is still a limit of 4GB which can not be changed

Note that with SharePoint Online, you can not change the file size limit , the way it is done for On Premise SharePoint.
