I could be wrong but I think that when you use -A on the filename, you need to specify the path as well unless the file is located in the same directory as where you call the script.( similiar to your unlink ("$dirPath\\$file") statement)

As a result, undef is being returned instead of the number of days since the file couldn't be found.
