My 1st question is related to changing to Chromium from Chrome. In just plugging those words in the search I came up with 3786 hits that I BEGAN to read and all I got was technical stuff unrelated (as far as I scanned) and was overwhelmingly daunting, so hopefully this will not aggravate y'all. I have all my saved stuff from Chrome migrated over into Chromium and am working through that. I read that Chrome has a couple different things (two that I understood: flash player and pdf viewer). Will that run into glitches opening saved websites and favorites now in Chromium? Do I need to add something to Chromium to be able to do what they did or does Linux cover that? Showing my ignorance there

I'm changing after enough aggravations with Microsoft and I'm happy about the changes but old dogs take longer to learn new tricks. I have a dual boot and would like to move all my files to the Linux side. I can access them fine but it is quit a string of clicks. Also, is this possible since they are on the Windows Side of my computer and the Linux side is a smaller partition. I have a 2 TB hard drive so there is lots of space but not for doing all things double. I have lots of pictures and audio files) Can I move the partition to make the Linux side bigger and the Windows smaller as I move stuff in the background? Or is there some easier way (I feel there is and I will learn it). I am able to follow clear steps for fixing things. The terminal does make me nervous as that is in the guts and I'm afraid of messing things up where I'll be done in.
Thanks again for any and all help here!
