Re^2: Perl hash keys not considered unique (updated)

[elfstones65]

You hit the nail on the head. Trying to have the hash with shall I say multiple levels was the cause.

 $files{"$processingFile"} = 1

Simply changing it to

 $files{"$processingFile"}{"file"} = $processingFile;

Worked!
Such a minor mistake, I was going nuts!

Much appreciated.
