| - A TWS (which stands for Tile World solution) file is a file with the .tws extension, which Tile World uses to save level scores and solutions, similar to an automatically recorded AVI. The key differences, however, are as such:
* An AVI is a simple video capture of the game screen that can be played back in any video player. A TWS file records the moves made by the player, and these moves are re-executed by Tile World during playback.
* The in-game sounds are also re-played during the playback of the TWS; AVI recording tools usually do not record sound.
* The player may pause the game as often as he likes when playing a level, and the pauses will be filtered out of the TWS recording. This will be important when using the Mouse Panel Glitch or in routes with heavy spring steps in reaction to monsters (frequently random ones), such as Blobnet, Block N Roll or Roller Coaster.
* AVIs can be played online or with almost any media player, so they are more accessible than the TWS.
* TWS files are inherently much smaller than AVI files (even compressed/zipped AVI files). The size of a TWS file comprising solutions for all levels in a levelset is of the order of kilobytes. The zipped AVI file for a single level requires a few megabytes.
* It is possible to verify that a solution still works on the updated version of a level (or a different level entirely) by attempting to play back the TWS on the new version.
* The TWS can also be played back using different tilesets and sounds.
* It is possible to generate an AVI from a TWS by capturing the TWS playback with ChipCap; this is done by beginning a ChipCap recording with an MS window open, and then switching to a Tile World window and playing back the desired TWS. This is known as a TWS-AVI, as it combines both solutions. The reverse method (an AVI-TWS) is obviously not possible, but fortunately Tile World is easier to record in. Additional features and restrictions in the use of TWS files arise from the way that Tile World currently handles them, and are described below.
