What Are SIM Files?
SIM files are Raster Image Files primarily associated with PDP-10 Simula-67 Compiler Source.
(Other files may also be using the SIM file extension. If you know of any other software using the SIM file extension, please contact us so that we can update our information accordingly.)
Opening SIM Files
The easiest way to open a SIM file is by double clicking on it, which will let the computer decide the best way to open it according to the Windows SIM file association settings.
If your computer opens your SIM file, but it's the incorrect application, you'll need to change your Windows registry file association settings. In other words, Windows is associating SIM file extensions with the wrong software program.
Quick Tip: Incorrect SIM file association errors can be a symptom of other underlying issues within your Windows operating system. These invalid entries can also produce associated symptoms such as slow Windows startups, computer freezes, and other PC performance issues.
If the SIM file fails to open, it is highly likely that your system lacks the application needed to open SIM files. It is common for several applications to share the same SIM file extension label, so it could take some trial and error to figure out what application actually opens your file (if any).
Thus, I highly recommend that you contact the source of your file for more details on what program you need to open your SIM file. This will save your a lot of time and headaches!
Remember to always take caution when opening files that come from unfamiliar sources or emails.
