Installing MT4 into multiple directories.

 
Hi Slawa,
I am running MT4 from several separate directories so I can service multiple accounts.

What is the proper way to copy MT4 into additional directory:
a) Should I simply copy a contents of already installed MT4 into additional new directory, or
b) Should I separately install MT4 into additional new directory.
 
If You need for same settings - a
In other cases a or b
 

I am not sure that my Post is in the right place I am not very savvy with these things, please advise

 

Having installed different Broker MT4's since Build 600 I am left with a lot of duplicate files/folders ie. in C:/Program Files/MT4 Broker A,  C:Users/Roaming/MT4 Broker A and  C:Users/Roaming/Terminal(Code for Broker A)

My question is can the first 2 directory entries be now deleted just leaving  C:Users/Roaming/Terminal(Code for Broker A) OR just the C:/Program Files/MT4 Broker A

I hope this makes sense as to what I am trying to say, anybody help please?
