Transfers Filter not working on macOS for AppleDouble, resource fork or ._* files

[PJVervoorn]

Using cyberduck 9.4.1 on macOS.
I am not sure if I’m doing something wrong or this is a bug (or future feature :) )...

What I see is that it creates files starting with ._ for all files and folders.
(When searching I see them being called AppleDouble or resource fork files.)
I am copying (audio) iles from one SFTP folder to another (on another server).
I added a filter \._.* to the download and upload filters, but the files are still created.

e.g.:

$ sudo find /mnt/media -name '._*' -type f
/mnt/media/Test/Yael Naïm/._07 Far Far.flac
/mnt/media/Test/Yael Naïm/._02 Too Long.flac
/mnt/media/Test/Yael Naïm/._04 Levater.flac
/mnt/media/Test/Yael Naïm/._09 7 Baboker.flac
/mnt/media/Test/Yael Naïm/._12 Pachad.flac
/mnt/media/Test/Yael Naïm/._11 Toxic.flac
/mnt/media/Test/Yael Naïm/._Folder.jpg
/mnt/media/Test/Yael Naïm/._05 Shelcha.flac
/mnt/media/Test/Yael Naïm/._03 New Soul.flac
/mnt/media/Test/Yael Naïm/._08 Yashanti.flac
/mnt/media/Test/Yael Naïm/._10 Lachlom.flac
/mnt/media/Test/Yael Naïm/._01 Paris.flac
/mnt/media/Test/Yael Naïm/._13 Endless Song of Happiness.flac
/mnt/media/Test/Yael Naïm/._06 Lonely.flac

It happens when I copy the entire tree or just a single folder.
I tried different variations: ^\..*$ \..* and positioned it at the start of the filter, at the end and in the middle.
Als including the path (./) does not help.

Thanks for reading., Peter
