在我运行fsckUbuntu 22.04.3 LTS 中的文件应用程序（又名 Nautilus）后，总是需要大约一分钟才能启动，然后在左侧边栏中显示大约 50-100 个文件图标/符号。
我该如何摆脱它们？它们是什么？请参阅附图。我在谷歌上没有找到这些图标的解释。当我点击它们时，什么也没有发生。许多“目录名称”都以方括号开头。
另一方面，替代文件管理器 Krusader 运行良好，没有问题。Ubuntu 安装在单独的、可启动的、持久的 USB 硬盘上。
据我所记得，一切都始于我通过从 Windows 10 访问删除此 USB 硬盘上的一些文件之后，而 Windows 10 是从我计算机的主硬盘启动的。此后，Ubuntu 无法启动，所以我用 修复了它fsck。之后，一切都恢复正常，只是 Finder 变慢并显示那些符号。我尝试使用终端删除无效的符号链接，但出现错误too many levels of symbolic links。

答案1
我终于解决了我的问题：我偶然尝试了文件管理器 Caja，我必须说它非常好，简而言之，它与 Nautilus 相同，看起来完全一样，但提供 2 个窗格，如 Krusader。此外，Caja 在名为“书签”的标题下向我展示了这些奇怪的文件符号。所以，这些符号只是书签！此外，Caja 有一个简单的选项来编辑和删除这些书签（Nautilus 没有），我在 Caja GUI 中做到了。所以向 Caja 点赞！我建议所有“Nautilus 又名 Files”用户改用 Caja。安装后，可以让 Caja 出现在应用程序列表中，然后添加到收藏夹/dock。
尽管如此，还是要感谢 petep 和 muru！
