The hl1 file extension is associated with Half-Life, a first-person shooter developed by Valve and released for Microsoft Windows in 1998. The game was also released for the PlayStation 2.
An hl1 file contains the saved game state, including the player's position and progress. Half-Life stores these files in the game's valve\SAVE\ folder by default.
The format is a legacy save format for the Windows version of Half-Life. It is intended to be used by the game rather than edited manually.
Open Half-Life and use its Load Game option to select the saved game. The game normally finds hl1 files in the Half-Life\valve\SAVE\ folder.
The file is not intended to be opened as a document in a general-purpose application.
An hl1 file cannot be meaningfully converted to a standard document or media format. To use the saved game, load it in the Windows version of Half-Life.
