copying files

April 2, 2007 | 6:10 pm


I also posted this in the jitter subforum as a follow up on a different question, however the people interested in this topic would probably be here, also for building the knowledge database.

I am trying to copy a file using javascript. however when I can not open the copied file. The player will give me an error, unable to open file.

What am I doing wrong here?

myfile = new File(filename, "read");;
if (myfile.isopen)
newName = new String(myfile.filename);
newName = newName.substring(0, newName.length – 4) + "_x.avi";
newFile = new File(location + newName, "readwrite", myfile.filetype);;
while (myfile.eof < = myfile.position)

There is probably a fundamental flaw in the while loop or the filetype, however I can not see my mistake.

Shouldn’t it be the other way round?

Yes you are absolutely right, I found that one out also.

However when I run the script the file gets copied ok, however Max crashes afterwards. Is there more stuff wrong here?

Well I’ve let go of the javascript solution and went into bash programming :)

With a simple script you can copy the file to a different location and have more control over the copy. using launchbrowser I can execute it, I think haven’t tested that part yet..

So thanks for your help. If you would like to take a look at the bash file you can mail me. I will not post it here because of the file alteration I also do.
