ZZ FTP Server is a free FTP Server for file management on your android devices from your portable computers or other handset devices. you can use it to transfer files from other devices with WIFI network or WIFI hotspot on your android device. ZZ FTP Server encoding file names with "UTF-8" with default setting. you'd better use a FTP client support "UTF-8" encoding. You can change the default encoding such as GBK and so on.
ZZ FTP Server does not require root permission, however, if your android device has been rooted, you can grant the App with root permission, then log in the FTP server with root user. because edit the system files is dangerous, we recommend you do not use the root user. Without root permission, you can log in the FTP Server with normal FTP user to access files on your sd cards.
