Storing folder directory from user prompted file selection

[#1]

This code not working. Please suggest how to modify it

file_name = Pick File ( "Select a file to open" ); // this line of code is working
folder_path = file_name << Get Directory() ; // this line of code not working.

Thanks.

try

folder_path = substr(file_name, 1, length( file_name)- 
	length(word(-1,file_name,"\/")))

That worked.

Thanks.

I like doing this using Word() with matrix to define the range of return (Word supports negative index)

Names Default To Here(1);

filepath = Convert File Path("$SAMPLE_DATA/Big Class.jmp", windows);

directory = Word([1 -2], filepath, "/\") || "\";

Show(filepath, directory);

If you don't need to have "/" or "\" at the end of your folder path, you can drop the || "\" part.
