Renaming issue

[Abele]

Hi,

I want signal a little issue on renaming function, if anyone try to
renaming more than three files with various file extension the panel
indicate a bad point to renaming, I already have seen this issue on
tryng to rename mixed files and folder, but I've thinking that is for the
presence both folder/s and file/s, instead the issue already is present on
files, I think the software lost the full stop of extension.
You can see a sample on images attached.
p.s.:
Interface is in Italian, but if required I can change in English, the error is unchanged.

What exactly is the problem? The file extensions are obviously different.

The problem is: can't rename, if pointining the cursor on 'placeholder' , the cursors to renaming, pointing to the first same letter present near to the 'placeholder', without consider the file extension.

With this specific set of names there are no common substrings, except for single characters.

The first common one is "r":

The shortest of the remaining strings is "ter.exe".
The algorithm now tests each of these characters starting with "t":
It immediately finds "t" to be common for all four trailing strings.
Incidentally, "t" is the last character of "ibe.bat", so the search is over.

The question is why should "." be prefered over "t" when both are equally long matches for all four strings.

Hi,

I know that no other program like 'FreeFileSync has a file/folder renaming function
and I'm happy for that, and it works very well for the most part, but I think a little prefix/suffix include/exclude function could be useful, because in my case i tried to rename about 150 files together and as a result i found some files with changed suffix, then the system indicated as unknown extension, that's what i was saying, now if you can 'force' the program NOT to search in the suffix as an option, i can have files with names (prefix) changed as i want or not, but readable, otherwise to avoid this i have to rename one by one, just a little suggestion to improve what is already great.

So you're wanting an 'Ignore Extension' feature?
And if Ignore Extension is enabled, a Rename would only work on the filename, excluding the extension.

Yes right, with this feature I think You complete the function 'renaming', and this can facilitate my work!

if you can make this change i am grateful!

It probably makes sense to handle file name and extension separately - since we're not dealing with arbitrary strings - and then combine the result:

Yes this is what I expect when try to renaming, this is well...

That's exactly what I meant, you're fast as a rocket and precise as a stopwatch! Thanks!
