Good day, This question about accessing files from the Wolfram Library Archive http://library.wolfram.com/ The problem is that by default when a user tries to download files from this server it does not support resume-able (partial) downloading of files. This is big trouble for users who have unstable Internet connection. Recently I have discovered that some files in this archive are mirrored in other directories on the Wolfram server with direct links and support for resume-able (partial) downloading. For example the file "UnevaluatedExpressions.nb" from the page http://library.wolfram.com/infocenter/Conferences/377/ could be directly downloaded from the page http://library.wolfram.com/conferences/devconf99/#programming with support for resume-able downloading: http://library.wolfram.com/conferences/devconf99/villegas/UnevaluatedExpressions.nb This is just an example. In this particular case I have no any problems with downloading of the file because the file is small. But many files in the Wolfram Library Archive have size tens of megabytes. Having unstable Internet connection through cellular telephone it is very annoying to see breaks of the connection because the user is forced to try downloading the file again from the start or do not download it at all. From the other side, unstable Internet connection is not a big problem when server supports partial downloading of files (for example, famous utility named "wget" completely solves the problem in this case). So my question: is there a method to be able to download files from the Wolfram Library Archive with support for resume-able (partial) downloading? Or is there a method to find another (mirror) link to file with support for partial downloading (as in the example above)?
