Inside "double quotes", the "\" character (which is the 'escape' character) needs to be escaped, using "\\".

So, your foreach should read:

foreach(@files) { system("c:\\midicsv\\midicsv.exe", "c:\\midicsv\\newmidi\\$_", "c:\ +\midicsv\\newcsv\\$_") }
This shows the mixing of a variable with a path, answering your first question.

For renaming files, you need to separate the pieces of the name, and replace the last piece.
This is typically done using regular expressions, but you can also use "split".

Here is a simplified example of replacing a trailing "csv" with "mid":

my $file = "C:\\temp\\somefile.csv"; my $midfile = $file; # copy it $midfile =~ s/\.csv$/.mid/i;
