Renumbering: managing conflicts of files with the same name

Hi!
I am testing the software and have encountered a problem I did not expect in a seemingly simple renumbering operation.
I have files with an existing numbering:
...
file-008
file-009
file-010
...
I would like to increment all the numbers by a fixed value (e.g. by 1):
...
file-008 --> file-009
file-009 --> file-010
file-010 --> file-011
...
I saw that the operation is not possible in one step because, acting on the files in alphabetical order (I think), a “file with the same name” error is given.
If, instead of renaming the files in alphabetical order, it were possible to proceed in reverse order, the error would not occur and the operation would be possible in one step.
Is it not possible for the program to handle cases like this?
Incidentally, in renumbering operations this happens frequently, even though the end result would not give rise to conflicts of files with the same name.
Can the program somehow handle these situations of conflicts of files with the same name, just checking that the end result has no conflicts and handling errors “under the hood”?
Thank you for your attention.

Hi Maurizio.
Click over the "Filename" and the files will be reorder in reverse mode. That will fix the problem

Hello Miguel, Maurizio,

Miguel, it seems that version 4.0b doesn't work that way (sorting works, but there are still errors when reverse sorting). Works perfectly in 3.9x, of course.

Here's two other ways to do this, if the sorting thing doesn't work for you:

METHOD 1:
Use MOVE batch mode. Tell the program to move your stuff to a new directory and the renumber method works flawlessly.

METHOD 2:
Say you absolutely want to keep the files in the same directory and moving is a deal-breaker. :)
Using Rename batch mode, set Name Collision Rule to Append number with a dash as the separator, then use a Replace method or a Remove pattern method to remove the dash and number following. Sorted in ascending order that will give you what you need.
EDIT: Actually this method seems to be glitchy in 4.0b upon further testing. It worked for a whle, until it didn't. But of course it works in 3.9x. END EDIT

There are probably several other methods to do it, but that should be enough. :) The moral of the story is, just because the obvious method doesn't work doesn't mean it can't be done.

Best wishes to all,
DF

Thank you both for your answers!
I have tried the suggested methods except moving and they work.
There remains some regret that these filename conflicts cannot be handled except with two actions instead of just one...

Hi,
try the latest beta version, 4.0.2, and click on the filename column to re-arrange all the files in reverse order, as already mentioned by Miguel.
To rename using only one method, use the following method:
