Best app for storing insensitive files
I use Dropbox for almost 6 years and I am happy with it to store and quickly share my files which are not to be treated as a secret (e.g. photos, temporary files)
Very easy to share files
Lack of end-to-end encryption
It gave the biggest free space (that time), and it was the most easy to use app amongst others.
Storing insensitive files.
It enables us to share photos amongst friends and documents with collegues easily.
There are security considerations which prevent me to use Dropbox for storing sensitive files there (there were some times when I did using TrueCypt containers).
