You should give the directory structure in the file/direcory and in the regex give .*txt instead of *.txt then add and use Get Filenames to see whther you are getting all the files . 这个不符合逻辑，但目前只能这样这样，正则表达式 .*xml 代表目录下所有的xml文件 What you enter as spec is a regular expression .*txt … means any file ending on txt (. is a wildcard character, * means 0 or more times).
