I installed Google Drive on the Parallels || Windows XP part of my MacBook Pro, as a part of my efforts to further embrace and utilize the cloud. Now, I have Google Drive installed on both the OS X and Windows XP sides of my Mac.
I installed Drive on the Windows side primarily because I still find it more convenient to use Macromedia Fireworks MX 2004, Dreamweaver and other older Windows programs over some of the newer Mac applications. Also, on Drive, I tend to organize files by which home network computer they used to reside on.
Now, on Google Drive, I have two primary folders for my MacBook Pro – OSX and Windows XP, with the files synced with the corresponding Mac location. Before I installed Google Drive on Parallels || Windows XP, anything I created with Windows programs just stayed there.
