Doyou and your colleague have Dropbox? Sometimes email programs do funny things to attachments, using Dropbox may solvethe issue. I also use a service called Hightail; it's a year-long subscription, but worth it: I can send files up to 2G and also have others upload files to me. It's always worked very well for meand for my clients. I send them an upload link, they do not have to have the Hightail service to use it. I'm sure there are othersimilar programs out there. -Gail On 9/28/17 6:56 PM, Linda Feltner wrote: > Alas, it's not for a Mac.
