Hi!

You might want to change your algorithm .. no need to store all directories to arrays.

Try the following

1) create 2 vars ($oldest_name; $oldest_age) and initialize the age to 0
2) pass through all files using File::Find (e.g. find(\&checkfile, $path);) - you'll need File::Find for this
3) in your callback-sub (e.g. checkfile) check if the current file is older than the oldest you found till now; if yes, store the data to your $oldest-variables (hint: File::stat might be helpful here)

now (when find() is finished) you have found the oldest file :-)
HTH, Rata
