imo this will mess up all your image files
work around, open your site in Dreamweaver and download a local copy of your site to this same usb stick then open Muse file and sync the assets to point back to the usb... if you have used any psd files then the originals should be copied onto this usb as well
now Muse will look back to this usb whenever it looks for assets and not the C, D, E drives of other computers
p.s, "hundreds of hi-def photos"? did you sync them to a cc library (best results) ... a synced images should just carry across as long as you log in to Adobe with the same id to publish
Thank you for your response.
Could you clarify what you're suggesting regarding Dreamweaver? I don't understand the process that you're recommending. Specifically, what do you mean by "sync the assets to point back to the usb"? If you, or anybody, could reply with more detailed instructions, I would be very interested in trying this method out.
