Opening SUM Files without Unknown Apple II File, Summary, or SciLab CAPE-OPEN Unit Operation Unit-operation Model Software Installed
Different software packages tend to sometimes share similar file types. Unknown Apple II File, Summary, and SciLab CAPE-OPEN Unit Operation Unit-operation Model are some of the popular programs that use the SUM file extension, so you should be able to use any of these three to open your file. You might even be able to find others by doing a quick Google search.
A word of warning, though. Be sure to scan any free software you download with a malware checker before running it on your computer.
If You Have Unknown Apple II File, Summary, or SciLab CAPE-OPEN Unit Operation Unit-operation Model Installed
If one of these software packages are already installed on your PC, but it still won't work to open your SUM file, you might have to check that the file associations are correct. Right-click on the file, select "Open With...", and then select Unknown Apple II File, Summary, or SciLab CAPE-OPEN Unit Operation Unit-operation Model. That will create an association between the SUM file extension and your chosen software.
Your SUM Might Be Corrupt
Finally, if you're still having issues opening your SUM file, download the file again or ask the sender to resend it. It's possible that your SUM file might be corrupt. As a last resort, contact the software developers to see if they may be of further assistance.
Here's a list of SUM-related software programs and their developers:
| Software | Developer |
|---|---|
| Unknown Apple II File | found on Golden Orchard Apple II CD Rom |
| Summary | Microsoft Developer |
| SciLab CAPE-OPEN Unit Operation Unit-operation Model | AmsterCHEM |
