Let’s get to the meat of it: With so many free or low-cost FTP
tools out there, do you need one that costs $120.00? If you are a
typical user, probably not. If your business relies on constant
file transfer–read on.
JaSFtp is a Java program which provides extremely powerful FTP
functionality. While you can just log on to an FTP site and
download a file or two with it–no one is stopping you–doing so
ignores the bulk of the program’s functionality. This is not a tool
for grabbing a few public files; it’s designed for mass uploading,
downloading, and copying, with powerful and deep scripting features
and options. While performing the simplest tasks (logging on to an
FTP server, downloading a file, and so on) is fairly intuitive,
truly getting the most out of this program will require extensive
reading of the documentation.
The main utility of the program for business users is in the
Tasks and Schedules. Tasks are collections of steps, such as “Log
on to Server; copy all files older than 2 weeks; delete those
files; then upload a new set of files from this directory”.
Schedules, in turn, set Tasks up to be run. Most, if not all,
commands and options available can use variables in place of
hard-coded values, thus, you may have one Task which sets a user
name to “CORP_USER” and another which simply has a variable for
“User Name” instead of a fixed value. There is, however, no
branching or looping in Tasks; they are sequential sequences of
Schedules can be set to run at fixed intervals such as every
hour, or only on Sundays, and so on. Scheduled tasks can be
executed immediately, or suspended. By default, JaSFtp launches
itself on startup, so it will faithfully execute your commands in
Because JaSFtp is a Java program, it can be used in
mixed-computing (PC, Mac, *nix) environments with limited
difficulty. The downside, of course, is that the interface is a bit
non-standard, a bit unattractive, and a bit ugly; this is the case
with pretty much all Java apps.
If your FTP usage is limited to one or two quick
uploads/downloads a month, or the like, this program probably isn’t
for you. If you are a heavy FTP user, corporate or private, though,
you might want to check it out. The price is high, but so is the
utility and flexibility.
