All files are text files. They are found in a folder on my computer. 
Assume that I know the names of some of the files I want to select from the 300 txt files.
How can I do this in R.
Atem.

I do not understand the question. If you already know the names what is the problem to select the files by names? 

If you have the names but not inside of R you have to find a name pattern to avoid typing them in. Is there a pattern, e.g. da.txt, db.txt, dc.txt?
