There are a variety of ways to do this. Suppose the current
working directory contains just those files you want to process.
And further suppose each of those files is a simple table of
numbers with each row being a separate data point and each
column being separated by either spaces or tabs. Then

FindFit[ReadList[#, Number, RecordLists->True], model,
parameters, variables]&/@FileNames[]

will do what you want. If any of my assumptions are incorrect,
simply replace ReadList with say Import and/or filter the list
of file names returned by FileNames.
