Hi Alison

This question is a close relative of that one about the string ;)

I think it really is just guesswork, as there are so many variables.

Thinking only of single PDF type submissions: a short document might 
still be a large file if it is full of images, formulas or heavy 
formatting; a long document might be a small file if it isn't. The size 
range will probably be from 100KB to 10MB.

IMO you might as well just estimate 1 file = 1MB, and therefore that 
100GB disk space will hold 100,000 files. What you actually get will be 
somewhere between one-tenth and ten-times that: a negligible degree of 
imprecision!

But somewhere with a well-established repository, like Soton ECS, might 
be able to suggest a sounder formula based on a statistical analysis of 
their holdings, perhaps broken down by type (articles, theses, etc.): if 
so, I'd love to see it too.

Hope this helps

Richard
