The same way you search any other Linux/Unix system. I.e., using opendir()/readir() from a C program, or /bin/ls from a shell program, etc. It's completely transparent. > Also is there any way to create a htree indexed directory explicitly? > using some command or tool? Once the dir_index feature is enabled, for all new directories and all directories which are only take one disk block grow to bigger than one disk block, they automatically get indexed. (There's no point indexing a single directory block since that's equivalent to a single leaf block.) To convert existing directories, you need to unmount the filesystem and use the command: e2fsck -fD /dev/hdXX This really should be added to an FAQ on ext4.wiki.kernel.org.... - Ted - To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
