This topic is discussed frequently, one of the last threads was
“Film roll vs folder” starting on 2015-11-16. Film rolls are related
to file system paths, each film roll will hold a subset of images of
a folder. Therefore, you would need a copy (or link) of the image in
several folders, and even then, the edit history would not be the
same. One could argue about other methods for collections, but I
guess at the moment tags is probably the closest you will get.
I did see that and I asked because P. Shanahan said:
A "film roll" is a *collection* of images whereas a folder is a
directory, a storage structure.

There is a difference since the film roll does only represent the
imported pictures and not the whole folder. As long as you do no
reimport the folder, you can add as many pictures to it as you want,
they will not show up in darktable. Furthermore, duplicated images
belong to the film roll as well.
What I'm trying to do is:
1. Collections
2. Virtual copies but each belonging to different collection
For this you have to form your collection with tags.
I was (and still am) afraid of importing twice the same photo from
different directory and not screw up the db
The photo is neither identified by file name alone nor by file contents,
but by file location + name, unique ID and/or version number. So there's
no problem having the same file in different locations. Of course,
parameter searches would most likely match both files and in the UI they
would only differ by file location and ID, therefore being hard to
distinguish as long as they are not edited or tagged differently or have
different other metadata.
Best regards
