This is a very simple method where you specify each filename manually for each file in the list. Line 1 will be the new name for the first item in the list, line 2 will be the new name for the second item in the list, and so on. If you have the new names as a list in an external source, like a CSV or Excel spreadsheet, you can copy and paste the list into this textfield or use the Load List button to load the list from a file.
The "Populate list" button will fill the list with the current filenames in the list. This is useful if you want to make a small change to all or some of the filenames in the list. You can then edit the list manually to make the changes you want.
Note: You can use tags in this method.
