Packs a punch for size. I have been using sfk for a while but recently had need to submit a bug request and received an acknowledgement, fix and commitment to correct in under a day. You don't get that with purchased apps!
Not recommended for advanced users. The server only works with the command line specific client because the command list is not standard, therefore other FTP clients will not work regarding server-side commands (eq: you cannot transfer multiple directories or a directory structure using a visual FTP client because the MKD command is not recognized!). Another bad thing is that you cannot set a range for server-side ports, the creation of them starts at 1024 (you cannot set a range like 40000-40200 if you need because of router settings (in fact, the FTP server assume that your computer is directly connected to internet and your firewall trust 100% this application). More of that, the FTP active mode is not working as the standard presume. All this make the application a bunch of nice ftp utilities, but a very primitive ftp server.
Interesting tool!! Other than this, One of the interesting tools that I found recently is DuplicateFilesDeleter.It is tool that can be used to find & remove duplicate files. It is a simple to use,but very effective tool to locate duplicate files in one or more selected search paths.It scans the files and compares them based on Byte for Byte Comparison, which ensures 100% accuracy. You can then choose to delete the selected duplicate or original files. The program is multi-threaded which enhances the performance immensely & performs scans very quickly.You should try it.
