Basically, an open file is one with no pawns of either colour on it. And a file with pawns of only one colour (either White or Black) is called as a half-open file.

The strategy behind an open file

Most chess players know that a common strategic objective for a rook or queen on an open file is to reach its seventh or eighth rank. Controlling the seventh rank is generally worth at least a pawn, as most of the opponent’s pawns will usually reside there.
