Here's a quick guide to using the software. It should be mostly intuitive, but then again I would say that :)
When you launch the application you will be presented with a largely blank screen, an example of which is shown below.
On the left hand side you see a representation of folders on your computer. This is similar to Windows Explorer/My Computer. Whenever you select a folder, the contents of that folder will be shown in the list to the right. Depending upon how you have configured the items on the Options menu you may see files, folders, a combination of the two, and possibly also "hidden" items.
You can select multiple files/folder, and this will configure what you want to rename. But you still need to configure how you want to rename files, and that is done in the window/button on the bottom left of the screen. Initially, you will need to press the Add New Step option.
Clicking the Add New Step button will display a window similar to this:
Listed here are all the possible rename facilities you can perform, and if you click an entry a brief description is shown underneath.
Click the entry you wish to add and click ok, and the entry will appear in the list of steps on the main screen.
Important note: you can add an entry as many times as you like, and they can be added in any sequence. This is an important point, as it allows you to build incredibly flexible renaming rules. For example, you may decide to remove a filename completely and replace it with the "date taken" from a photograph and an incrementing number. Or you may choose to simply convert a filename to upper case. The list of combinations is endless.
Back on the main screen, when you select a renaming "step", you will see properties associated with that step. Here is an example:
This allows you to configure how that step will operate. And yes, if you have the same "step type" listed several times, each step can have different criteria So it would be perfectly possible to add a date-time of a photograph "date taken" in DDMMYY format, followed by a date-time of "file creation date" in YYMMDD format, if you so wish.
Once you have multiple steps you can change the position of the step, disable a step, duplicate a step etc.
Once you are happy with the list of steps you have built, and you have selected one or more files, then you can click the Preview button to see what the new names will look like. You haven't renamed any files yet.
If you aren't happy with the filenames then select a single file and click View > Step Through - this will step through item on the list of steps and show you the resulting filename at the end of each step. This makes it easier to work out what is going on.
Finally, when you are ready to rename your files, hit the Rename button. This will actually perform the rename operation. When files are renamed they are renamed via an intermediate name, so this makes it straightforward for you to rename A to Band B to A without getting a conflict.
If anything goes wrong with the rename operation, all the changes made will be undone/rewound, so you won't be left with a mess :-) In the unlikely event of this not happening, the files will all be present and will have a prefix of a random string, so you will easily be able to work out what the files are.
The last rename operation can also be undone manually via a menu option.
Finally, all rename operations are logged to a log folder in the same place as the application program on your drive.
