It would be convenient if any files generated as a result of using a Revit .rvt file would all be automatically saved in the same locations as the main file, without having to go through options and re-allocate the location every time you change to another project. I understand that .001 backups are generated in the same file location as the main .rvt file, however .rws, .dat, and any other generated files should automatically allocate their file path to that of the main .rvt file. I'm been in contact with Autodesk and the information I'm receiving at the moment suggests that it's not possible to change the file save settings so that any all additionally generated files are saved in the file location of that particular .rvt file.
