Like all other software giants, Steam also has technical problems on its client where games may fail to launch properly or undergo some random error. For this purpose, Steam has added a feature to verify the integrity of all the game files in your client.

This feature compares the game files you have on your PC with those of the latest version located on the Steam servers. If it senses some discrepancy, it replaces or adds any files. While downloading a huge game, it is a possibility that some of the downloaded files may be corrupted and because of this, the game may fail to launch as required.

Steam has a manifest downloaded in its computer. All of the downloaded files are listed in it along with their versions. There are hundreds of game files present on your computer, instead of comparing each and every file, it compares the manifest on your computer with the manifest on the Steam servers.  If it senses anything different, it fixes it accordingly.
