Folder is a convenient term. Yes it is a directory. I am a Mac, Vax, 
Mainframe, Irix, Sun OS,  Solaris, Linux, and occasionally HPUX person.

In regard to your  second point, this is an example of a problem in 
bioinformatics. The program is written for all of the data to be in one 
directory without sub dirs. It is a structure that works with smaller 
sample sizes. But the assembly of a genome (even for a bacteria) winds 
up being large numbers of sequence files from many lab and BLAST runs.

The ultimate solution is to rewrite the program so that it will deal 
with its data being distributed in a directory.
