I've created a number of maps that I need to e-mail to a co-worker who does not share a network with me. E-mailing is limiting the size of the files that I can send. While majority of the file there is no issue, a few of the files are significantly larger than the others (160,000KB- 260,000KB versus 1-7KB) and is preventing me from sending them even in a compressed folder.
What is strange is that all the maps contain the same layers but are displaying different geographic locations. The scale and resolution is also the same.
I'm wondering if there may be anything else that is causing this difference in file size.
