Is it possible to rename a file in MQL5?

 
I searched through File* functions in the docs, but didn't find anything.
 

Yes, open the resource file and the new file, copy the whole content from the source and the target, save the new file and delete the source.

You can write your own single function for that.

As long as you are adhering to the file system sandbox, yes.

You can use this function to do it
