What is "flat structure" mean in the introduction part of the project homepage?

[chenttuuvv]

It seems that I fail to find any definition of this term in Google.com. I guess it may refer to the meaning that all block files are located in the same directory, is that right?

Queston 2 : Does this phrase "在块设备基础上建立自有的文件系统，减少EXT3等文件系统数据碎片带来的性能损耗" mean that TFS does not use API provided by VFS layer and write data to file /dev/sda1 directly ?

Question 1

“Flat structure“ means tfs doesn’t have a hierarchical directory structure similar to traditional filesystem， you can simply think that all the files are located in the same root path.

Question 2

Tfs uses ext4(or some other fs) to store block which contains many small files in it, not directly use raw device.
