You can have Iron open PDF and Windows Media Player files by default.
However, these files are not opened in a temporary folder, they are saved in the downloaded files folder.
By time, this folder will grow to a considerable size if you don't empty it manually.
Even if this is not a great issue it is still annoying. There doesn't seem to be any way of setting preferences to delete these files after closing the PDF viewer or Windows Media Player. Using various Application cleaners doesn't seem to solve this problem either. This is one thing you would want in a new release!
Im using Iron Portable, Version 22.0.1250.0 (160000)
Thoughts and suggestions are appreciated!
