DirectoryStorageService: Remove files with same filenameTag?

[philippsteffan]

Hi,

we use the DirectoryStorageService to store DICOM files. As directory structure and filenameTag we use something similar to "DicomTag/Date/SOPInstanceUID". The content of the DicomTag is user-defined and therefore error-prone. (incoming DicomTag=A, an hour later the corrected DicomTag=B arrives, the SOPInstanceUID is identical).

Is it possible to add an optional feature, which deletes all files with the same filenameTag (=SOPInstanceUID in our case), so that users can correct their mistakes without user interaction? Something like a Map which maps filenameTag to Path and ensures that the old file (in a different directory) is removed, before the new one is written?

What's the best approach to implement this features? Would it be possible to add such a feature to the upstream CTP repository?
