[BioC] What is the maximaze number(size) of cel files can PC handle?

[Joyce Gu]

Hello,
I am wondering how super is your computer? I actually want to ask some 
question about this. My computer can not even handle 64 cel files. I have 1 GB 
RAM.
Is any limitation on that? Is it the memory problem or something else?

Thanks
Joyce
