[BioC] how to put together 600 files from the 5.0 Affy SNPchip

I'm new in this mailing list and also using bioconductor. I'd
appreciate your feedback on this: I have 622 files that correspond to
622 samples genotyped for the SNPs in the 5.0 SNPChip from Affymetrix.
Each file consists of two columns of almost 500 K rows (plus 4 lines
at the begining that I won't need). The number of rows are the same in
every file. I would need to put all these files together, where the
first column is common to all of them (SNP names) (so I just need it
once in the big file). Once I have all the columns one after the other
I would also need to paste a column with the chromosome number for
each SNP (which is in another file, just this info alone). Do you know
if there's any way to do this with Bioconductor?.
