I want to use a Surface Pro tablet to import photos from an SD card, then I want to review the photos in Lightroom, delete the ones I don't want, and eventually get the photos off the Surface Pro and on to an external drive connected to my iMac. I currently have my iMac set up for file sharing and do this with my other Macs. 1. Is there an easy way to use the Surface Pro to copy the files from it to the drive connected to the iMac through my wireless home network? 2. Does this introduce any performance issues, or security concerns? Thanks.
