No.
I read it on site, posted by someone who is more an expert than I am.
Once I have to use code deeper into Linux , I want to be careful not to wipe out the main disk used in the PC
Everything on that is on a safe back-up already.
Many apps on PC I don't need, most things are done with phone anyway.
But Dropbox I want to be able to use on all the three devices I use.
Thanks for you post .
