On my HP desktop in File Explorer, I have many files under Dropbox. This list differs wildly from my FIle Explorer on my HP laptop, my phone, and Dropbox.com.
CLicking on either of the Dropbox icons in the system try, they all say your files are up to date.
I m paying the 2GB subscription, but if I can't quickly get to my files (and many of them are huge mp4 files I use for work), I may as well struggle along with local external drives.
