Description : You save a photo or document, you want to add a colon or semi-colon; like I just did. What's the big deal and why can't it be saved?
Last Answer : You can't use a colon in a file name on Mac either, but you can use a semi-colon. Slashes don't work either. My guess is because they have other functions and putting them in names of files is misleading ... URLs and such. Just like in Windows, you can't call anything con . Try it; it won't work.
