Specific File Unzip

[Ectropian]

Setting an application like Archive Utility App to automatically unzip a file downloaded to a default directory in Chrome isn't too hard. What I'm trying to do is unzip a specifically named file to a specific folder when that file is added to a directory and disregard the rest of the files downloaded to that directory.

I'm not very familiary with Automator Scripts, although normal linux command line isn't a problem. Example: I download the same file every day with a specific file name. When I download JUST that file, I need it automatically unzipped to a specific folder inside say my /dropbox folder, which in turn will automatically update all other associated folders on associated computers. So I'm looking for an "If myfile.zip, then unzip to ~/dropbox/myfiles - then delete the old mfile.zip"

Ideas?
