The above code prints "FileOpen OK" however, there is no file to be seen in the common folder /MQL5/Files, nor in the tester sandbox /Files/ location.

Usually the human is in error so, am i missing something here?

Works for me from just running the EA and from the Tester.

Thanks for investigating. 

Strange, i run MT5 build 2085. Running the EA also gives me zero file.

I am running same build. Windows 7.

When i remove the FILE_COMMON flag, i do get the file in /MQL5/Files when i run the EA and when i run EA in Tester the file is also created in the agents folder. Just as you would expect.

But with FILE_COMMON, it creates no files, not in either of the two locations.

Because it should not. Not in /files. Not in /tester/files. Only in the common/files folder.

[Enrique Dangeroux]

For some reason i had /MQL5/Files in mind as common files folder. Corrected now.

Thanks you both!
