When I am creating a CSV file for the shopping cart. I have a question about options. (below is from the FAQ)

"Value: When the Catalog is exported in .TXT or .CSV format, this parameter is taken from the Product Variationsfield of the Product Settings | Options window.
If you are preparing a .TXT or .CSV file to import, the Product Variations list can be entered using the "|" character in the following format:
... ; Variation1 |Variation2 | Variation3 ; ....
Continue until you have added all the necessary Variations."

is that a backslash? I am putting in bolts and instead of me creating 150 of the same bolt, differnt size (and 150 images) I am creating the bolt IE  1/4 wedge anchor , Options are sizes (1/4 x 2-1/4 > 1/4 x 3-3/4) AND I was going to imput the sub option with grades of matrial normally there is 4.

If that is a back slash then it will not show up correctly in shopping cart. I could just put the sizes in the shoping cart, but when I export and import again wouldn't the options be wrong? (I am thinking about the future if I need to export and then import again for whatever reason) 

My questions

A) is that a backslash that will mess up my number options?

B) if it is, is there a way around to imput sizes and still export/import again?

C) am I going to have to go the long way around and insert a bunch of photos and waste a lot of page space? (I have about 25000 fastener combonations if include adding 2-4 grades per size)
