unable to export dicom files

[Farinelli56]

Hi all,
I'm working on a project where I have to import dicom files from CD, anonymize, and export to a folder on my Mac.
Yesterday things were working smoothly, but today with a set of CDs from another source, I encountered an issue I was unable to solve: the dicom files import OK, I can process them (either through the anonymize command or by editing specific dicom header tags), but when I try to export I get empty folders. I can export to tiff OK.
When I try to export after anonymization, I get the following error (see screenshot): "couldn't create directory..."
A folder is create at the specified place, but it is empty. Simple export does the same without an error message.
I tried the same without any editing, i.e., import from CD, and export to disk, with the same error. The folders are created, but they are empty.
Any help would be greatly appreciated.
Thanks,
M

update: I created a workaround by requesting the images to be saved as zip files.
Once that worked, I was able to save uncompressed images...very strange.
I also note that the images are loaded as read-only, even if I upload the files.
