In Mac, you can get information such as File size, File Type, File Name, Folder Contents, Location on Mac, Date Created, Date Modified, Entension about any file / folder as well as other functions like locking the File / Folder, Making it Read only, etc.
So what's the long drawn complicated procedure for all this ?
Well, first you select the file and then press Command-I. Complicated, huh ? ( For the sarcasm impaired, you want to skip over that last part )
