OneClickFTP is a FTP-Client written in C /Qt4, with which you can Upload Files with just a few Clicks (unfortunately not one, but never more than two). To do that you have to specify Profiles with the Server, Username, Password an the desired Files.
OneClickFTP offers a lot of features like the Im- and Export of Profiles wich makes it easy to share them with other people. Or the possibility of prompting for a password, when trying to transfer files. It it also possible to check the files for "Last modified"-date or size before transferring. OneClickFTP provides safe up- ad downloads, by uploading a file to a temporary name and renaming it after it has been sucessfully uploaded.
