Hi All, My first question is where is this index actually in Git. Is that a some folder or some location? Second, how really Git keep information about index? Third, in git community book it says " If you blow the index away entirely, you generally haven't lost any information as long as you have the name of the tree that it described". I didn't get this statement can any one explain this in simple words. And finally why git add is used for both adding untrack file as well as to move file to stage area? Is there any particular reason for this?
