Delete InDesign Recovery Folder

Hi,

I'm using InDesign CS3 on MAC OS...

I m trying to delete the InDesign Recover folder...

var f = Folder("MAC:Users:<username>:Library:Caches:Adobe InDesign:Version 5.0:InDesign Recovery:");

f.remove();

I was able to perform this operation few weeks back but now i'm not able to do...

Manually the folder can be deleted.

I m able to delete any other folder in the same path but not this one alone... I tried moving this folder to another path and deleting, but still couldnt delete... I also tried emptying the contents of this folder and deleting but was not able to do...

I m confused, what could be the reason?

Can someone pls help me.....

Thank You...
