How can I view hidden files in the Finder?

I noticed that whenever I add files and delete them, their physical space remains on the disk drive. I uninstalled NTFS Tuxera and I still have the same problem. So I had to insert the disk under my other Windows laptop to locate the ./#### files and delete them. I was surprised that I couldn't locate those files in Finder, but windows allowed me to view them. Is there a way to have more control over what files are viewed in Finder?
