Command Groups
NOTE. Using bac
k slas h as a path separator may produce some unexpected
results, depending on how your application treats escaped characters. Many
applications recognize the sequence of back slash followed by an alphabetic
character as an escaped character, and, as such, interpret that alphabetic
character as a control character. For example, the sequence "\n" may be
interpreted as a newline character; "\t" may be interpreted as a tab character. To
ensure that
this interpretation does not occur, you can use double back slashes.
For example, "E:\\testfile.txt".
