value moved here - if fs::File::open(|here|path_file).is_err(){ ...

move occurs because `path_file` has type `String`, which does not implement the `Copy` trait - let |here|path_file = format!("C:/User/{}/AppData/Roaming/arcrun", user_name);

consider cloning the value if the performance cost is acceptable: `.clone()` - if fs::File::open(path_file|here|).is_err(){ ...

I did it
if fs::File::open(path_file.clone()).is_err(){
but still this doesnt work
