If not send the file to me off list, and I'll post a link to it for you.

I believe the internal size shows the size of the file uncompressed, and as such it is much much larger. > Any help would be greatly appreciated. Not much help, but better then nout. -- Douglas Furlong Systems Administrator Firebox.com T: 0870 420 4475 F: 0870 220 2178
