Many of us started here:
When I made the transition, I laid some groundwork on the Windows side first. I picked up a free copy of Syncback and set it to copy "my documents" and a few other folders I care about to a network drive every night at 1am. The day I brought home my 2008 Macbook, I simply switched off my Dell and moved it out of the way, plugged in and turned on my Macbook, copied files down from the server that had been backed up from Windows and I was up and running. Of course I had to go download a few freeware programs to get stuff done. One was OpenOffice which later became LibreOffice. I also bought iWork (Pages/Keynote/Numbers) which is now free with any new Mac purchase.
You'll now have a life, enjoy
All you had to do was ask...but there's one thing that has been plaguing me.
In windows, I can highlight a bunch of folders and right-click->properties and it will give me the TOTAL amount of files and space in one window. I have yet been able to figure out how to do it in OSX without having to make a parent folder, move all the folders into that folder, and then "get info" on the parent. Not ideal.
(What happens on the OSX side, is that if I get info for multiple folders, it pops up an 'info screen' for each folder selected...)
Not sure if that info will be useful for the OP, but I know a few people that have that same issue. Seems like it's a basic function not to be able to do?
