This is my Custom Function and I want to edit it


You could change the pathpos test to something like the following to reduce function calls:

result = FMFilePath; // NOTE: no longer need to prefix line-return to path

pathpos = Case(
"filemac:" = Left( result; 8 ); 8;
"imagemac:" = Left( result; 9 ); 9;
"file:" = Left( result; 5 ); 5;

Note that also removes the need to prefix a line-return symbol to the path, since we test only the leftmost characters. You can do the same for the Windows portion.
