没有采用caja那么复杂的方法，直接在右键菜单里进行判断，如果选中的文件有以x-nautilus-desktop开头，就不显示压缩选项。
会以x-nautilus-desktop开头的文件满足两个规则： 1，在桌面上。 2，主文件夹、回收站、网络设置、各种移动U盘在桌面上的显示盘符文件，本地磁盘挂载后在桌面上显示的盘符文件，等。 ps：桌面上的其他普通文件会以file:开头，所以能够正常显示压缩选项。 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to file-roller in Ubuntu. https://bugs.launchpad.net/bugs/1403377 Title: The compress function works abnormal for trash, disk and so on Status in Ubuntu Kylin: New Status in file-roller package in Ubuntu: New Bug description: The compress function works abnormal for trash, disk and so on. 右键点击回收站、磁盘等，选择压缩，点击确认提示压缩成功，实际上未生成压缩文件 Steps: 1.
