UpdateBuilder project

I need some files, during my application update, to be added to the application subdirectory. Unfortunately no mater what I write to "Target directory" field in UpdateBuilder file list - the file always is downloaded to application location.
Is it a special format required?

If the file to be updated can be overwritten while the EXE is running, set WebUpdate.ExtractCAB = true, then it will use TargetDir= in the [file%] section.
Otherwise, add the relative target folder to the CAB file for this file to be updated.
