It's possible but difficult to be specific given the code you've posted ....

For me, the easiest way is to read data from multiple files into a single
array, then run through the array performing your regressions on each data
set -- something like ....

	SetDirecory@NotebookDirectory[];
	ifiles = FileNames["*.txt"]
	idata = Import[#]& /@ ifiles;

	rset = FindFit[#, model, {}, {}]& /@ idata;

should do the trick.

Regards,

Dave.
