Where to find the SasView log file

Whenever you run SasView it silently creates/appends debugging information to a log file. If you are reporting a technical problem with SasView, it can be helpful to the Development Team if you send us the log file. Where the log file resides depends on your operating system:

  • Windows: C:\Users\your_username\sasview.txt
  • Mac OS:
  • Linux: ~/sasview.txt
