In the J-file format the fibers are
listed by color, number (if applicable), and each color has one or more checkboxes to
allow you to check whether or not you own the fiber or need to purchase it.
The .csv format files contain the same
information except that the checkboxes are replaced by a field that will contain either a
1 or a 0 (in these files they are all 0's so that you can enter the data that you want).
This has to do with the way that J-file converts the checkboxes but it's not really
a problem. Most databases will easily convert the 1's & 0's into checkboxes or
Y/N's.
