The procedure to upload resources is also covered in this video:

All of the resources except the fonts and styles can be put into sub-folders.

To create a sub-folder for a specific resource you simply select the resource type in the library, select the main folder (if you want to create the folder inside another folder) here:

and then click the New Folder icon on the left:

- and type in the name of the new folder in the pop up window:

If you want to delete a sub-folder in the library, then you simple place the mouse of the folder. On the very right you will see the icon below. Click the icon to delete the folder (or file):

It is possible (but not recommended as no references to the resources inside are updated) to rename a sub-folder and other resources in the Library from the web-interface. In order to do that you should select the main folder in the Library and then click on the pencil icon to the right of the folder, that you want to rename:

Now this warning window will pop up:

You should only proceed, if you are 100% sure, that the resources inside of this folder are not used by any other elements in InterFormNG2. If you are sure, you can simply type the new name of the folder and click Rename.

Now you can select all or some of the objects:

If you click the checkbox marked with 1, then you select all object. Click the checkbox again to de-select all the objects. 

You can select/de-select each object by clicking the checkbox next to the object like indicated with 2 on the image above. 

After you have selected the object you can use the action above the list to either delete or move the objects to another folder.

Please note, that this is a simple text editor. It does not verify the syntax of the file, so you need to ensure yourself, that the file is still valid after you have made your changes.

You can open and edit the object types mentioned above by simply double clicking on the object. Then you will see this:

You can start editing the file, if you click the EDIT icon on the top left. Then the window looks like below:

In the top right you can see the two actions available:

1. Find & replace
2. Edit text

Find & replace

If you click the Find & replace icon on the top, the top left corner of the editor changes into this:

Here you have these entry fields and icons:

• Find Text
  Here you can type a text, that you want to search for and replace. All occurrences of this text will be replaced if you later click the Replace icon. The search is not case sensitive.

• Replace Text
  The text written here is the text, that are to replace all occurrences of the Find text above.

• Replace
  When you click this icon, then all occurrences of Find text are replaced with the Replace text. In the bottom right a pop-up window will let you know how many texts, that was replaced.

• Edit text
  If you click this icon, then you jump to the edit text option.

• Close
  If you regret and do not want to do a search & replace, then you can click this icon to cancel the choice and get back.
  In the bottom right you have these icons: 
  
  
  The changes to the file are not saved until you click the save icon. If you click the cancel icon without saving the last changes you are asked if the changes should be discarded.

• Undo the changes
  After you have run a search and replace the undo icon is enabled:  
  
  
  If you click the undo icon the last search and replace run is rolled back.

Edit text

If you click Edit text in the file editor, then you will see a screen like below:

On the right you see a slider, which you can use to see the lower part of the file.

To edit the file you simply replace, delete or add the text by typing/deleting.

You can even place the cursor inside the edit window and hold down left <CTRL> while pressing the 'A' key to select all the text and you can then click <CTRL> and 'C' to copy the text into the clipboard and paste it into your favorite editor and here the changes here and then copy the text back when you are done.

Please note, that this is a simple text editor. It does not verify the syntax of the file, so you need to ensure yourself, that the file is still valid.

• Undo
  The undo icon in the top rolls back the last change in the editor.

• Save
  Remember to click the Save icon on the bottom right, when you want to save changes to the file. No actual changes are done until the save icon has been clicked.

• Cancel
  If you click the Cancel icon the text editor is closed, but not before asking if InterFormNG2 should discard changes if there are any unsaved changes.
