import many files and generate an `id' variable as the file name.

Dear All, Suppose that I have the following 3 files (in fact, about 4,000 similar files). The file name is 1, 2, 4 with extension xlsx. I wish to import each file, then generate an `id' variable with values all equal to the file name 1, 2, and 4, for all observations in the file, respectively. Finally, I need to -append- them together. Any suggestions?
