SaveToFile fails.  
1. Is there a way to find out why?  It has been working fine for several years, until now.
2. Is there a limit to the length of the path?  The length might be a bit longer than used previously, but well below the Windows path length maximum.

Using C and the 1711 library.

Thank you.

There is not much to the SaveToFile function. A drill down through the code gets us to this API call which tests for save capability:

<result> = CreateFileW(PWideChar(FileName), GENERIC_READ or GENERIC_WRITE,
    0, nil, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, 0)

If that returns false, you cannot save a file.
 
In Delphi I could call System.GetLastError - RAD Studio API Documentation and I might learn "why". I do not know if you have that option in C.

My guess is that the OS is saying "No" for some reason. Maybe permissions, bad path, file in use, etc. but I don't think there is anything about QPL that should be the source of the issue.

Like swb1 told already.
Perhaps the file you wanna save is locked by another process?
Try LastErrorCode to get a more detailed error.
Cheers,
