4sync Comments

Data "Loan sharks"

Negative Comment by Damian_Adelle
about 4sync Oct 2014

I got out of nowhere a mail from the staff two days ago telling me that my account all of a sudden turned into a "free-premium-trial" account, and I put that in quotes because the account itself doesn't exist anymore (at least mine), they tell me that if I don't upgrade premium, they will delete my stuff, that's it, you want your things back?, go premium. I say stay out of these san franciscan criminals digital den.

Too slow!

Negative Comment by Venom88
about 4sync and Dropbox Jul 2012

I tried 4sync on Windows and I have to say that it's too slow to load itself and to upload files (and I think it is blocked too: the number of files to upload is always the same).

I highly prefer Dropbox.
