Exchange folder

The exchange folder can be the user's i_o folder (normally...\Users\Windows_user_name\Documents\Nemetschek\Allplan\2026\Usr\Local\i_o) or the i_o folder in a named project (e.g. ...\Data\Allplan\Allplan 2026\Prj\*.prj\i_o). For example, DWG/DXF files are written into this folder or read from there.

Note: Under normal circumstances, we strongly recommend choosing the user's data exchange folder.
