Other than being just a data extractor tool AlgoDocs was designed to let users keep their documents in an organized way by offering a File Manager in which you can create folders and subfolders. Therefore, instead of uploading your documents into a common pool and mixing them up, you can create folders/subfolders in your file manager to keep your documents organized and grouped by importing them to specific folders. So, file manager with folders lets you keep your documents clean and easily accessible.
Although folders play a vital role in terms of keeping documents organized and easily accessible they do not have a special meaning in AlgoDocs. You can survive even with a single 'root' folder )))
