Creating folders allows anyone to keep your company's boards organized according to - (for ex.) team, time and/or projects.
Simply click the New Tab and then choose New Folder.
Why are they so helpful? With folders, all boards related to one topic can be found inside of them which keeps your monday.com side bar very clean and sleek looking.
The ability to open/close folders (as seen above) is possible so that not all the boards need to be seen, but rather by the folder name. If the folder is open, you have the ability to drag/drop boards into other folders.
**NOTE: Subfolders are not available with monday.com, please contact firstname.lastname@example.org if you have any further questions. :)
