Always Use Lowercase for Filenames

Blackboard CE 6.1.1 has a nasty habit of renaming files that you upload or import using all lowercase. Further, there’s a known bug that if you have two filenames that are identical (except for the case, the course will generate a general exception error when trying to copy it into a new course shell). So the morale of the story is name all your files using only lowercase letters. Due to Blackboard CE 6.1.1’s renaming of an imported or uploaded file:

WICKED.PDF becomes wicked.pdf
Wicked.pdf becomes wicked.pdf
and
Wicked.PDF also becomes wicked.pdf

Then you’ve potentially got multiple files with the same filename and your course is headed for trouble…if it already has a file created under a previous version of CE that includes upper and lowercase letters in the filename.
