Hi,
.twsupport is the file extension of
Archicad Teamwork Support Packages. Sharing these files with support can help Graphisoft engineers to investigate issues, like crashes, Send & Receive issues or other similar cases.
If you are not about to contact your local support, then you can just delete them, it won't do any harm. On the other hand, if you are interested what could happen here, sending this package (all 25 files) to your local support can help.
I hope I could answer all your questions, but let me know if you have any further questions.
Kind regards,
Noémi
