Hi Mr. Muskrat, I just tried your suggestion:

use File::Copy;
copy("a/b/*.txt","a/");
[download]

unfortunately it doesn't seem to work for me. It works fine for an individual file, say:

use File::Copy;
copy("a/b/ccc.txt","a/");
[download]

not a problem, but when the * is put in it doesn't seem to do its job. Any ideas?
