Data, Computing and Information
There are HTML exercises in this course, which are offered on CD in HTML format. HTML (hyper text markup language) is a bunch of pages with markup, which refer to each other. At the exercises I've seen so far, these references do not care whether the filenames are upper or lower case.
This doesn't disturb Windows users at all, since the whole operating system is case insensitive. But it really matters for UNIX and derivate users, since these exercises simply don't work for us.
It is possible to create a script to rename all the files respectively, the alternative is the tedious approach of going through all of them and renaming them by hand.
