Download Filesize from analog.com

Hi again,

I just forwarded this comment to the ADI webmaster (this can be done on
their homepage):

"Hi, a little comment: we are customers of the VisualDSP package. There
are frequent updates of this on the web page (very good idea). However,
these are usually quite large files (up to 50MB). I found it very good
practice to split these files up (into, say, 2MB packages). This has two
advantages:
1. If there was a transmission error (this happens about 2-10% of the
downloaded stuff), one must just download the erroneous file, instead of
the whole thing again.
2. If there is a bottleneck somewhere, one can download several packages
simoultaneously - speeds up the downloading process.

The ZIP programs all support zipping to several files, this should pose
no problem." If you agree with me, maybe you could also mention something to that
extent to their webmaster - if there are several complaints, they might
consider it seriously. Good hacking,
Andor




Get a download manager called 'GetRight'. If a download drops out, it will
hook up again and continue, even across sessions. Andor Bariska wrote:

The files are FTP'able, and FTP supports downloading starting in the
middle of a file, so you just need an FTP client that can do that. The
latest Netscape for Windows (4.73) has Smart Download, and also fixes
an important security bug. Most standalone FTP programs support
resuming an interrupted download, although you may need the registered
version to get that feature.

I disagree. If there's a bottleneck, you won't get better performance
with more streams, and you'll create more overhead on client and server
for the additional connections. Better to use a smart downloader that
can queue several files at once. Another good one is WS_FTP from
Ipswitch (http://www.ipswitch.com). A registered copy is only $40.
