Hello, I am new to coding and am having a problem. I made one robot, compiled it, ran it, and everything worked as it should. Then I tried to code another robot and when I compiled it I got an error saying unsupported file extension. I then tried to create a few more robots thinking that it was just a one time error and I've gotten the same thing every time, so it seems that for the moment I am not able to compile any of my work. Ive tried to look this up for how to fix it but I can't seem to find anything anywhere about it. If you know how to fix this please let me know!

Do you really expect an answer with the information you've given? There are no mind readers here and our crystal balls are cracked.

The same problem happens to me too.
When I open  a new file, If I make it in a sub-folder like C:\Program Files (x86)\... MT4\MQL4\Indicators\the sub-folder or I make a new file in the main Indicators/Expert Advisers folder and then move it to a sub-folder, in both cases (Some times) I get Unsupported file extension error.


It happened to me only during the last 2-3 weeks.

You are right. Same thing happen to me. Use "Save as" option to save the file format as mq4, then problem solved. thank totsh!
