File system that uses tags rather than folders?

Question

My files are a mess, I try to structure them into folders with names that describe what they are in a recursive class break-down sense but later on I have trouble finding the fi

Answer 1

Here are some file systems which I found using google.

TagFS - "Tag Semantics for Hierarchical File Systems" paper by Stephan Bloehdorn and Max Völkel, 2006 http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.60.4187

dhtfs - "Tagging based filesystem, providing dynamic directory hierarchies based on tags associated with files" a usable implementation, last release 2007 http://code.google.com/p/dhtfs/

Tagsistant - "A reasoning semantic filesystem for Linux and BSD" project under active development http://www.tagsistant.net/

Leaftag - "Tagging for the Linux desktop" another implementation, last release 2006 http://www.chipx86.com/w/index.php/Leaftag

On integration with OSes, I dont think it should be that difficult. OSes are deeply dependent on file system hierarchy's but tag based file system can mimic directory structure. For example in a tag based file system the path /etc/init.d will give all the files that are tagged with exactly two tags i.e 'etc' and 'init.d'. For files which are tagged with other tags as well as these two tags, their extra tags can appear as directories inside /etc/init.d. If there is a file a.txt with three tags i.e 'etc', 'init.d' & 'asdf' then 'asdf' will appear as directory inside /etc/init.d and full path of a.txt will become /etc/init.d/asdf/a.txt.
