SharePoint document list: different column views for different folders

julisp Unfortunately, No.

This is how SharePoint document libraries work. When you add a column in document library view, it is added at library level & not specific folder/file level.

So, if you change any library view settings (like grouping/filters/sorting), change will be applied at document library level & not folder/file level.

There is no SharePoint out of the box way to show/hide the column for particular content types (folder/file).

However, you can create a separate "view" in your document library if it helps. Check: Create, change, or delete a view of a list or library
