Drive space issue

 

Good afternoon all - we are running the current version of MT4 and are encountering a problem with drive C running out of space when running a back test on AUDNZD each time.  This generates a 384GB file in the USER/####/App Date/roaming/MetaQuoates/Terminal folder each time.

 

Within this folder are a number of folders with names of seemingly random numbers and letters, with the structure of the MT4 inside it.  Within Tester/history, we find the fxt file for this dataset.

 

It seems to happen only with this dataset, but keeps creating a file of around 384GB.  We have updated the data recently since the first incident from Learn To Trade's sources, but it happened again yesterday.

 

Any suggestions on this at all?

 

Many thanks 

 
Just to add - I have checked the shortcuts and none of these are using the /portable switch, and other data sets appear to be fine.
