When you view a Dreamweaver site in the expanded Files panel, information about the files and folders is displayed in columns. For example, you can see the file type or the date a file was modified.
You can customize the columns by doing any of the following (some operations are only available for columns you add, not default columns):
Reorder or realign columns
Add new columns (for a maximum of 10 columns)
Hide columns (except the filename column)
Designate columns to be shared with all users connected to a site
Delete columns (custom columns only)
Rename columns (custom columns only)
Associate columns with a Design Note (custom columns only)
Change the order of the columns
Select a column name, and then
click the up or down arrow button to change the position of the
selected column.
Add, delete, or change detail columns
Sort by any detail column in the Files panel
