This is probably a *really* old version of this. Modern notebook directories look like `sage_notebook.sagenb`

. May we ask what the lectures are? It's possible there is an updated version. In any case, if you upload the worksheet (`.sws`

) files as Dirk explains, this directory will be recreated in your own `.sage`

directory (usually located in your `$HOME`

directory).

This is probably a *really* old version of this. Modern notebook directories look like `sage_notebook.sagenb`

. May we ask what the lectures are? It's possible there is an updated version. In any case, if you upload the worksheet (`.sws`

) files as Dirk explains, this directory will be recreated in your own `.sage`

directory (usually located in your `$HOME`

directory).

Edit: In personal correspondence, you verified that this is from http://modular.math.washington.edu/edu/2007/spring/bsd/sage_notebook.tar.bz2 from the website
http://modular.math.washington.edu/edu/2007/spring/bsd/; this is indeed from an archaic version of Sage. You could conceivably compress each of the directories in the directory `worksheets`

into a .bz2 file and then rename it as `.sws`

and try to upload it, but I suspect that won't work, given that the internals are different.

In this particular case, I would write a script to look at the directory `pub`

and extract the `worksheet.txt`

file in each folder in there to be uploaded to your Sage notebook; it's not perfect but I just tried it and they do work, though it looks like some of them may be incomplete in various ways. In truth, you may want to see if there is a more recent version of some of William's stuff on the BSD conjecture, which there likely is! Good luck.
