The only issue I see with paperless-ngx is that you cannot use an existing folder structure, or has that changed in the meantime?
I would like to access the documents via paperless-ngx but would also like to preserve and continue to use my existing folder structure, especially to make retrieval of documents easier for someone else than me in case of emergency or if I cannot use paperless-ngx for whatever reason.
I have made the experience that following along a clearly defined logical folder structure is easier for someone who hasn't spend ours creating the structure themselves or doesn't know about paperless-ngx.
Absolutely agree and that's where paperless-ngx will shine. But for my documents I prefer a tool agnostic (and therefore future proof) way of storing. In case of multiple places, where a document could go, I always think "what's the most likely way I will be looking for this document in the future?".
