Git Question

What are the "loose objects" that the Git GUI refers to?

When I open the Git GUI, I get a popup message that refers to

loose objects
. I did
git gc
and that removed the message.

What are
loose objects
and how could I prevent this from occurring again?

Answer Source

An object (blobs, trees, and commits) with SHA say - 810cae53e0f622d6804f063c04a83dbc3a11b7ca will be stored at


( the split in first two characters to improve performance of the File system as now not all the objects are stored in the same directory)

Objects stored as above are referred to as Loose objects.

When you start up with your repo, you mostly have loose objects. As the number goes high, it becomes inefficient and they are stored in a pack file. Such objects are called packed objects.

 git gc

is what you run to pack objects (Usually loose objects that are not needed and few weeks old are also removed and with --prune=<date> option you can force remove loose objects that are no longer needed. Like when you amend a commit. The old commit object is no longer needed. )
