-NOTE: DATVault will download any updates into the same directory that contains the respective JSON file. Any existing DATs for that system will have a ''.old'' extension appended to the end of the filename.+The information in the JSON file is compared against the DATVault repository to determine if there are updates available to download. If the JSON file you have does not match the latest version available by DATVault, then the corresponding DAT has an update. When you update a DAT, the JSON file is also updated.

 +|**⚠ CAUTION:** \\ DATVault only manages DAT updates for DATs it has downloaded. It will NOT update DATs you have placed into your DATRoot manually. Its advised to remove any manually managed DATs before having DATVault manage those DATs.| 
 + 
 +|**ⓘ NOTE:** \\  DATVault will download any updates into the same directory that contains the respective JSON file. Before a DAT is updated, the current DAT you have (which is referenced in your JSON file) will be renamed with a ''.old'' extension. DATVault does not automatically remove these ''.old'' DATs, so you may want to periodically delete them if you do not wish to archive old DATs.|

 +|**ⓘ NOTE:** \\ Some DATs for disc based systems have accompanying cue sheets. DATVault will download cue packs to a folder called ''cues'' in your Primary ToSort directory.|
