i request you to provide me the code
because i had try using FileOpen command in mql4 i am successfully able to read or wite under metaquote folder but not in c:\ or in d: \
so i request you to provide me the code for creating / reading / writing an text file ( or csv file ) in c:\ or in d:\
You have multiple possibilities, the easier is probably creating a sym link. Navigate your cmd window directory to your data MQ4/File and run
mklink /j mydrive c:\
Then you have entire drive inside the sandbox.
