To force a different alignment
By default, a folder session aligns files and subfolders by name, left and right. Click the New button 
to add an Alignment Override.
Note The easiest way to manually align two items in a folder session is to right-click the first item, choose Align With, then click the second item.
To override file format associations
The Enabled file formats list lets you override which file formats will be used by this folder session. A file format is listed in bold if its state in this session is different from its global enabled state. You can create a custom file format for use in this session that is not used in the global list.
