Syncplify.me FTP! is the free, graphical FTP(S) and SFTP client by syncplify.me. It supports the FTP, FTPS (FTP over SSL, both implicit and explicit) and SFTP protocols, and it's very easy to use as well as extremely fast.
Protocol support: FTP, FTPS, and SFTP
Multi-tab interface: keep multiple file transfer tabs open at the same time
Supports large files (greater than 2 GB)
Sleek and easy to use GUI
Supports both IPv4 and IPv6
Advanced wildcard-based file transfer
In-session editing of remote files
Synchro-browsing (with optional automatic creation of missing folders)
We designed the GUI to be easier to use than most competitors. On top of that we have support for IPv6 and wildcard-based file transfer which are not commonly found in competitors' solutions. And unlike FileZilla (for example) our implementation of the synchronized browsing feature can automatically create the missing folders during the navigation.
Anyone who needs to transfer files to/from FTP, FTPS, and SFTP servers. We're targeting mostly lower-competence users who want a sleek GUI and maximum ease-of-use.
