how does one test a path (coming in as a string argument to some method of the js) is a file or a folder?

perhaps there's a very simple way but my attempts with the filetype or pathname methods of a Folder object don't seem to do the trick...

yes, i was tryin that but i wasn't sure hot to test the "success" of an open-as-folder attempt.

Okay, I see that there is no good test for success w/ Folder. You 

could try the other way, try to open as a file and check the

could try the other way, try to open as a file and check the  
File.isopen property.

Another way to is to make a system call and do "rm ". If 

the thing you're testing gets deleted, then it was a file.

how would you make a system call and
would that "rm" work on xp?


Methinks that was a joke, no? unless of course you want to delete the

Obviously a ridiculous "solution", but you can make system calls with  
Java relatively easily. Might need to execute different system call  
on XP than OS X, of course.

i know you can make system calls easily with Java,

Testing if something is a file or a folder is really easy in JAVA. I

would just create a tiny mxj utility for doing this.

turns out, joshua's 2nd suggestion of attempting to open as a File and test the isopen property works perfectly.

thanks all.

Whenever I do this, I wonder why my clients never came back to me...;-)

I'm trying to implement Joshua's solution, testing if a file is open to see if it exists. I'm half-way there. If the file DOES exist, changing the access to "readwrite", then writeline doesn't seem to do anything!

foo = new File("foolio.txt","readwrite");

foo.writeline("New file created here today!");

var foo = new File("foolio.txt");
if(!foo.isopen)
{
    post("File foolio.txt doesn't exist.n");
    foo = new File("foolio.txt","readwrite");
    foo.writeline("New file created here today!");
}
else
{
    post("File exists.n");
    foo.access = "readwrite";
    foo.writeline("Overwriting stuff.");
	foo.eof = foo.position;

The line "Overwtiing stuff." never gets written to the file...

Hey, sorry the reply is a bit late, but in case you haven't solved this yet try the code below. You need to access the file object without creating or opening anything at the beginning and then it should work.

// filefinder.js

var target = this.patcher.filepath.slice(0,this.patcher.filepath.lastIndexOf("/")+1)+"foolio.txt";
var foo = new File();

function bang() {
    foo.open();
    if(!foo.isopen) {
        post("File foolio.txt doesn't exist.n");
        foo = new File(target,"readwrite");
        foo.writeline("New file created here today!");
    } else {
        post("File exists.n");
        foo.position = foo.eof;
        foo.writeline("Overwriting stuff.");
    }
    foo.close();
}

autowatch = 1;

// EOF
