BeFTP for BlackBerry v. 2.57 see revision history
Compact BlackBerry FTP client and media card file manager - now with many new features!
BeFTP is a free BlackBerry FTP client application.
It was developed by BEIKS in response popular demand for downloading and installing large reference files like dictionaries, e-books and travel phrase books directly the device's media card.
As the BlackBerry built-in Web browser does not offer download capability to arbitrary file types, but only applications and a very limited set of pre-defined media file types, the need for a solution that would allow any file to anywhere on the media card was apparent.
Free BlackBerry FTP client for infrequent, non-commercial use
The freely downloadable, unregistered version of BeFTP comes pre-configured to connect to the BEIKS public FTP site, from where BEIKS customers can download various reference content for the other popular BEIKS applications. Those users are granted a limited license to use BeFTP for downloading from the BEIKS public file server without having to pay for using it.
The same version can also be configured to connect to other FTP sites, still at no cost, however the connection configuration will not be remembered after the program is closed.
This makes BeFTP practically free FTP download client for infrequent file transfer needs.
Frequent application use and use for commercial purposes, including enterprise deployments, are only allowed upon registration.
Multiple, configurable accounts for registered users
The registered and the enterprise version of BeFTP allow for multiple accounts to be created and remembered between application sessions.
Create a list of FTP hosts, specify display name, host address and port, then quickly connect to that host whenever you need.
Media card file browser and manager
BeFTP allows you to browse both the internal file system and media card's contents, create and erase directories and files.
Future versions may include cut/copy/paste functionality, simple file viewer and more.
