hi linuxcommander,
i am also a boxcryptor customer, who made some attempts with boxcryptor portable on linux (especially linux mint).
do you also have the problem that boxcryptor portable is very - very - slow on linux? it's pretty much not useable if you want to de-/encrypt files over 500 MB, because it takes ages to do so.
do you have a better experience with boxcryptor portable?
thanks for sharing!
