I used to use an FTP server app for transferring files from my computer to my sd card. Recently this has stopped working. I understand that it is because of an update in kitkat that makes the permissions for reading, writing, and executing files more stringent. I'm familiar with linux, so I'm guessing I need to make a folder on my sd card with rwx permissions for the ftp app, right? Or is the issue more complicated than that? Any help would be appreciated. Thanks.
