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 https://docwiki.embarcadero.com/Libraries/Sydney/en/System.GetLastError" rel="nofollow - 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.
