I believe that Skyline cannot do anything with this data.
We have a different program called "SeeMS.exe" which you get when you install ProteoWizard:
SeeMS.exe will let you look at the spectra in that file. I do not understand what kind of spectra they are.
SeeMS says that their MS Level is zero, which means that Skyline will not be able to do anything with them.
Typically what you need to do with Skyline is first tell Skyline which molecules you are interested in looking at. For small molecules you usually have to do "File > Import > Transition List" and import a CSV file containing a list of your molecules and transitions. If you wanted Skyline to extract data from MS1 or MS2 spectra you would then have to go to "Settings > Transition Settings > Full Scan" and tell Skyline what to do with those spectra.
After you have told Skyline which transitions to extract chromatograms for you can usually use the "File > Import > Results" menu item to extract chromatograms.
The small molecule tutorial is a great place to start:
However, Skyline is not the right software for your data file.
