splited file encrypted with blowfish secure?

Hi all,

I have a question about the security of my encryption. I have written
a program in php which splits a file in small parts, encrypts each of
them with blowfish and put it together. It uses the same key for every
encryption of the parts. The reason I do it like this is that php is
only allowed
to use 16MB of memory space and so it cannot encrypt or decrypt large
files.

Here is my question. Is it less secure when I encrypt a file not as
one big file? I mean, is it easier for someone to get the key or plain
data of a file if he has 100 parts encrypted with the same key in
comparison with only having one big file?

Thanks a lot
