哈希索引目录
当我对各种文件系统感到好奇时,我正在浏览 minix 文件系统。在阅读 ext2 支持的功能时,我发现哈希索引目录就是其中之一。
有人可以告诉我这是什么吗?
I was just going through the minix filesystem when I got curious about the various filesystems out there. On reading about the features that are supported by ext2 I saw that hash indexed directories
is one among them.
Could someone enlighten me on as to what this is?

有关 Ext2/3 Htree 目录索引的详细信息,请参阅下面的链接:

基本上,文件系统使用哈希树来存储目录条目,而不是线性列表。这会显着提高目录查找操作的性能。

Basically the filesystem uses a hash tree to store directory entries, rather than a linear list. That results in a siginificant performance improvement in directory lookup operations.
