Finally got it working. Needed to accurately follow your instructions…
qucs.exe -”c:\Users\Tom Hajjar\.qucsstudio”
I created the following folder and put some test projects and an empty user_lib folder.
C:\Users\Tom Hajjar\.qucsstudio
Using a Dos prompt I get the following results:
I’m having trouble getting this to work. I have both versions of QucsStudio in separate folders as well as Qucs.
C:\QucsStudio – 2.5.7
C:\QucsStudio – 3.3.2
2.5.7 only gave a warning about incompatible libraries in “user_lib”. 3.3.2 won’t load it’s “built-in” libraries like Z-Diodes nor User libraries due to finding “other” incompatible libraries in “C:\Users\Tom Hajjar\.qucs\user_lib”
My goal is to put QucsStudio User files in a new folder “C:\Users\Tom Hajjar\.qucsstudio” to segregate QucsStudio from Qucs.
Unfortunately I haven’t figured out what QucsStudio shortcut property changes that work.

Another issue is the mismatch between the number of parameters for a component in Qucs versus QucsStudio.
Capacitor Example:
Qucs capacitor has 3 parameters. C, V, Symbol
QucsStudio capacitor has 5. C, G, V, Symbol, Package
G is blank and you are stuffing “neutral” into 2 fields thus causing an error in QucsStudio. Errors occur for diodes and other components as well.
When I used to manually convert Qucs to QucsStudio, I would not try to match all the extra parameters. Obviously I can manually edit each component to get rid of errors. It’s harder for components with a large number of parameters like a diode.
Any reason you can’t match the rotation of sources? All are placed rotated -90 deg.
You also don’t handle anything but “0.0.19” in the header. 0.0.19, 0.0.20 and even older examples are common.
Neither issue is a big deal.

I did a quick test of an old RF filter file I had using AC Power sources and S-parameter analysis. The two Sources P1 and P2 were rotated 90 deg. Another problem that is not a real issue for QucsStudio is a formula for Group Delay used in older Qucs had used the math function “unwrap” that QucsStudio didn’t know. I’m sure there are other issues as well.
I have a huge number of Project files for Qucs, Qucs-S and QucsStudio. Some are the same schematics solved using the three different versions of “Qucs”
The two file formats are different. Only method I know, assuming you know the differences, is use a text editor to manually change the file. Once schematic opens you need to make changes to sources and other items to get the file to work. Not worth the effort unless the schematic is very large.
Thanks for the response. I can’t be the only one using both Qucs and QucsStudio. I have hundreds of old simulations in both and having to manually edit the files in a text editor to convert them is a pain especially if a matching model or component doesn’t exist.
It would be nice to be able to change the default location of the files/libraries so there won’t be conflicts.
QucsStudio 2.5.7 didn’t care if “Qucs” and “QucsStudio” User libraries were in C:\Users\…\.qucs\user_lib.
On startup you got one “Library is Corrupt” message and the “native” QucsStudio libraries are available.QucsStudio 3.3.2 On startup however gives a “Library is Corrupt” message and then doesn’t load the “user” or “native” QucsStudio libraries.
Is there a reason for this change?
