I didn't find a cloud provider with zero knowledge that have a good price and fill all my requirements.
So I decided to use my OneDrive account with Boxcryptor. It work great, even on android with word or excel !
My only concerne is how to acces to a folder on android ?
I want to use encrypt folders in an app that need access to the all folder. For exemple, I have a folder with files with .md extension.
My app (markor) need to access to the all folder because a file can have a link to another file etc...
Is it even possible with boxcryptor ?
Thanks for your help !
