sprite packer - where is spritesheet in the project folder?

when the sprite packer finishes the job it should produce bitmap used in the game am i right?
anybody knows where the image might be located in project?

As per the Unity manual for Sprite Packer it states under heading ‘Other’ that:

Atlases are cached in
Project\Library\AtlasCache. Deleting
this folder and then launching Unity
will force atlases to be repacked.
Unity must be closed when doing so.

Now you can check what is present in that folder.
