What free cataloging software can be used under Linux?

Question

Cataloging

Hello. There is a directory structure (obtained by the tree command) you need to take notes - why each file in these directories is needed. I started to return the document in the open office - but this is very inconvenient. Too big structure. So I dreamed of such a contraption: there is a structure like in the screw explorer. And now you can press the pluses and minuses, expand and collapse the branches, and each directory or file (it seems quite officially called the leaves of the tree, right?) You can leave notes. It's great if you can make a short and extended form for a record. In a short form, for example, the caption “brain thought parser”, or you can expand it and see more about this parser.
Now, the actual questions:
- How do people act in my case? What do they use. Shouldn't programmers have some description of the project's directory structure at hand? Or am I completely clueless about development?
- Is there a shaitan program I described or saw your bike?
- If you are sawing your bike, do you know a nice module for python, in which it will be easy to screw the functionality described by me with drop-down trees to the form (for example, on Tkinter)?

We are talking about Linux.

Answer 1

Try any Mind Mapper. It is convenient to describe the tree structure in them.

Answer 2

In the git, when commits, there are comments on files and folders in theory.

Answer 3

I understand that this is not at all what you want, but. When I had a similar task (when studying the Yii framework), I took advantage of the ability to stick notes to folders and files in nautilus. Folders or files that have notes are marked with the corresponding icons in nautilus - you can always open the properties and see the note.

Answer 4

I have a text file for each project with a description of the project, it contains, among other things, a file tree with a brief description of each file.

Answer 5

Total Commander can add file descriptions to descript.ion (ctrl+z)

Answer 6

Nepomuk in KDE allows you to store and search through tons of metadata.
