Filtering in Calc
You can select multiple filters in different columns and all will be applied, also on other selectors. In my example: When filtering ‘Folder 4’ by ‘Documents’ the selector for ‘Folder 5’ wont let you select ‘Screenshots’ any more. No scripting necessary.
use some Blob text
These blob texts will follow a structure, too (they must be linked to the files by name or another nomenclature). So reading these and filling additional columns will also be possible using a script.
