Any number of subfolders can be placed under the folder with /ode/ shortcut. The application tries to recognize which folders are subfolders just to create structure, and which are the actual homework vault folders, i.e., end folders with student files. The recognition rules are as follows:

• The operation menus are only displayed for homework vaults, for what is recognized as a folder there is only the "change settings" operation and clicks to the Study Materials (i.e. File Manager).
• Any folder for which any upload right is set is evaluated as a homework vault. If no such right is set, the folder is evaluated as a homework vault in case that:
  • If it doesn't have any more folders underneath it.
  • If there are any files uploaded into it (i.e. the folder used to function as a homework vault and the right to upload has expired or the teacher has removed it).

In the application, you can clearly see all the homework vaults, their subfolders and the number of files in them. The expanded view shows those homework vaults where is some file of any student included in the Teacher’s Notebook selection. You can always see the homework vaults for selected seminar groups as expanded, even if there is no file in them. On the other hand, if you have more than 100 people in your selection, you must expand the homework vault by clicking on its name.

For each homework vault, you will see a list of operations that you can use to work with the homework vault and links to the operations in the File Manager. Unlike the File Manager, there are a few extra operations available here:

• Access to the notebook used for evaluation of files (if you created it when you set up the homework vault) – In the notebook you will find links to the submitted files of each student. If there are changes in the number of students in the seminar group or course for which the homework vault is open, you can validate the notebook,
• Sending an email to students – e.g. those who have not yet submitted their file or to all those who have access to the folder, etc.,
• Sending information on changes by email – you can have information on changes in selected homework vaults sent to you by email via the Events application.

However, there are some operations with homework vault that you can perform only in the File Manager, for example:

• Assigning a combination of upload rights to the homework vault, e.g. only students in the seminar and students registered for the exam etc. are allowed to upload.
• Deleting a homework vault that already has some submitted folders or files.
• File operations – moving, editing content, renaming, etc.
