An organized and well-thought-out folder structure is crucial to keep track of your projects and be in full control of their states.
PROJECTS | - FINISHED | | - Finished Project 1 | | - Finished Project 2 | - SANDBOX | | - Test Project 1 | | - Test Project 2 | - Active Project 1 | - Active Project 2
First there are my 'Active projects'. I try to keep them around 5-10, so it's easier to get track of them. Those are all the projects I have a clear vision about what to build and why I need to finish them.
When an 'Active project' gets finished, I move it into the 'Finished' folder, so my root is clearer. I might sort them even more across 'Years' subfolders in the future, once I start to lose control.
Finally, there is the 'Sandbox' folder. This is my testing folder, an idea bank. I usually start my ideas there and move them outside if I see a future for them, so they become my 'Active projects'. I do regular cleanups there, by removing the ideas with lesser potential.
I would love to see your approaches on how you organize the projects.
