FolderJet

In spite of the fact that it makes it easier to create sub-directories and arrange information based on file association and topic, the problem with tree-structured folders is that there is always the risk of placing the files in other directories. Moreover, depending on the number of sub-directories you include, the path to a file can be long and hence, harder to access or use in applications.
FolderJet is an application that provides you with an alternative to the tree structure arrangement of folders so that you can easily access the desired section via shortcuts.

Comes with a simplistic, yet customizable GUI

After a quick and uneventful setup, you are welcomed by a clean interface that consists of six tabs. While initially they display a summary of the drives connected to your computer, you can navigate to the desired section and save the stacks, so that you can find the quick path easily after you restart your system.
You should know that the program allows you to customize the UI using various color themes, a feature that can make it overall more convenient for you to work with and maybe, less straining on your eyes.

It enables you to create auto shortcuts

The highlight of the utility stems from the fact that you can open sub-folders with just one click, as the application creates auto shortcuts from the folders included in the path. The feature can be useful when you are working on a complex project that contains an extensive library for instance.
In addition, the app provides you with an option to organize your categories of directories based on the topics or projects you are involved in. Simply put, the structure provided can make time-consuming tasks like opening and re-arranging directories obsolete. On top of that, you no longer need to create, organize and manage shortcuts.

An alternative for the standard folder tree format

All in all, if you are working with large directories on a regular basis and would like to trade the cluttered look of tree-structures for an option that you can access easier, then perhaps FolderJet could lend you a hand.
