Hey everyone, I've been using an external HD filled with all of my documents/files as my standard HD which I connect to whatever computer I might have access to at a time and browse/use it this way. For documents such as credit cards and other accounts I've made a .txt file in a password protected .dmg and up until now it worked fine and served me just as I needed since I'm only surrounded by Macs in my house. However, I am soon going to be using other computers running Windows as well from now on, so I was wondering what is the alternative to .dmg so I can store and password protect my sensitive documents in it and still be able to use it (read & write) on both Mac and Windows. Thank you in-advance. Other info in-case it matters: I'm not very paranoid about safety from hacking. It's having my HD fall into the wrong hands (possibly getting mugged?) what I'm afraid of, and have a random stranger read my sensitive data. I'm open to all kinds of alternatives, besides a cloud service, as I don't always have internet access.
