LabelTop

LabelTop lets you add labels to your files and folders, in order to find them easier in a virtual library. It's similar to adding tags. This is an easy-to-use software application with intuitive options that even less experienced users can quickly figure out.
It adopts a user-friendly interface that lists several predefined labels to help you get started. Labels can be created, renamed or deleted.

Attach labels to files and folders

In order to attach a label to a file or folder, all you have to do is indicate an item using the file browser or drag-and-drop support. Although this is not clearly understood through the interface, LabelTop gives you the possibility to attach multiple labels to the same file or folder. For example, if you have a software application that performs multiple tasks, then you can attach a label which explains each task.

Locate files and folders by labels

Once you've put everything together, you can access each label to view all containing item (including full paths and sizes), check out a list with all labels and their items by just clicking inside the search box, as well as swiftly locate files, folders or labels using this search tool, which shows real-time results and accepts partial matches.
Additional options become available by opening the right-click menu in the search results list. You can launch apps or open files, visit their location in Windows Explorer, apply additional labels or remove them, as well as copy, move, rename or delete files and folders.

Evaluation and conclusion

There were no stability issues in our tests, thanks to the fact that the software utility didn't hang, crash or prompt error messages. It had minimal impact on computer performance, running on low CPU and RAM.
Too bad that it hasn't been updated for a long time, since its options need a little fine-tuning. The project seems to be discontinued. Otherwise, LabelTop offers a simple and elegant method for keeping track of files and folders via labels.
