Hi Niall,

This is a causes by a Windows 10 limite on the amount of open files it can 
handle (around 1024 I think).  Problems happen when you have thousands of 
opened shapefile that need to be merged (like when you use and external program 
to find the file extent for thousands of files on a HD drive).  This is not a 
QGIS issue. Saga loads everything into memory so the problem is not seen in 
SAGA.  It does not keep a handle on the files once they are opened.
