What is steam?

   How to Back up Steam Games without losing data

3.  Go to C:\Program Files (x86)\Steam\steamapps   
   

This is default location, if you installed steam somewhere else, go to that particular location\steamapps

1. You need to copy the files from “common” folder and “appmanifest_291480.acf” files. Common folder = contains the game data which you need to copy.
   Appmanifest_xxxxxx = contains the game info regarding the data location and its complete info and the complete game status.

So you need both of them to back up your data.

1. If you have multiple appmanifest files, that means you have multiple games installed on your pc or laptop. I only installed one, So I have only one appmanifest file.  
   

How to distinguish appmanifest files of games?

It’s very simple, all you need to do is open appmanifest file with notepad++, there you can see the following info.
For example, name = warface
"AppState"
{
"appid" "291480"
"Universe" "1"

"name" "Warface"

  "StateFlags"          "4"  
  "installdir"          "Warface"  
  "LastUpdated"          "1496072474"  
  "UpdateResult"          "0"  
  "SizeOnDisk"          "9757498404"  
  "buildid"          "1692246"  
  "LastOwner"          "76561198362763634"  

"BytesToDownload"          "7224237648"  
  "BytesDownloaded"          "7224237648"  

  "AutoUpdateBehavior"          "0"  
  "AllowOtherDownloadsWhileRunning"          "0"  
  "UserConfig"  
  {  
       "language"          "english"  
  }  
  "InstalledDepots"  
  {  
       "291481"  
       {  
            "manifest"          "7299738716313125141"  
       }  
  }  
  "MountedDepots"  
  {  
       "291481"          "7299738716313125141"  
  }  

}

1.  Now Copy the appmanifest and the game folder from common into a safe location.
                      For example: external hard drive or some other local disk. 
   

2. That’s it now it’s ready to be shared to someone else or can be used on a later date without downloading the file.
