We don’t have sub directories as such. However here are a few “workarounds to make files easy to locate:

• In the main “Library” section you can use the drop down to find files by project
• There is also a direct link to each file – so you can send this to your team to make it easy for them to find a file. (Find this link in the library. Your Team Member must be logged in to access the file which will download onto their device).
• We also a have a search feature in the library.
• Plus files can be attached to Tasks, so you can use the task tagging feature (more info) to effectively tag the file.
