The module I downloaded expanded into a bunch of files

Sometimes your web browser will automatically expand module files, since they are really just zip archives. You can tell this happened if there are a bunch of files and folders, including among others, an “image” folder. This seems to be more common on Macintosh systems.

What you need to do is prevent your browser from doing this automatic expansion. The way to go about this depends on the browser that you use:

  • Firefox
    • Right click (Mac: control-click) on the link and choose “Save Link As …” from the popup menu.
  • Safari (Macintosh) either
    • Right click (control-click) on the link and choose “Download Linked File” from the popup menu.
    • or edit the Safari “General” preferences and make sure ‘open “safe” files’ is not checked.
