+The behaviour you described is intended, git annex preserves all versions of all files. Those old file are refered in git annex documentation as `unused`, so you can search for this term. Following are main commands:
+
+- [git annex unused](https://git-annex.branchable.com/git-annex-unused/)
+- [git annex dropunused](https://git-annex.branchable.com/git-annex-dropunused/)
+- [git annex drop --unused](https://git-annex.branchable.com/git-annex-drop/)
