Managing files is a legitimate use case in my opinion and I’m going to explore it more too.
Did you already notice that you can change the path of an asset manually?
I mean, when you upload an asset you will get a link like this:
[Name.pdf](../assets/Name_1658000515517_0.pdf)
If in your assets folder you create a subfolder you can edit the link like the following:
[Name.pdf](../subfolder/Name_1658000515517_0.pdf)
(notice that it’s ../subfolder/ and not ../assets/subfolder/ in the link above as one would expect, I don’t know why).
Maybe you can move all the files you want to manage into the assets folder and manually link them in Logseq when needed instead of using the Upload an asset command?
Is this enough to address your use case?
Edit: don’t forget that URLs work too, so you can link files on a web server too. For example the following PDF can be annotated as a local one:
