7z Zipを抽出して正しいディレクトリ構造にするにはどうすればよいですか?

XXXhostXXX:temp XXXuserXXX$ ls -a dir1/
.   ..  a.txt   b.txt
XXXhostXXX:temp XXXuserXXX$ pwd
/Users/XXXuserXXX/temp
XXXhostXXX:temp XXXuserXXX$ 7z a -t7z dir1 dir1

なぜ最後にa.txtb.txtdir1から削除されたのですか?

xコマンドの代わりにe を試してみてください。例えば

7za x test.7z

私のために働き、完全なディレクトリ構造を保持しました
