My PowerBuilder app is using Appeon 2017 R2 Build 1756 with PFC.

The pfc_n_cst_filesrvwin32 object has a function of_dirlist() which lists all the files in a directory. It uses the Win API calls FindFirstFileA() and FindNextFileA().

The first argument to FindFirstFileA is a directory or path and a filename eg "O:\TestPath\*.FXC". This works fine EXCEPT when the "O:" drive is a mapped drive on a PC running a 64bit operating system like Win Server 2012.

I have googled this and I've been directed to using the Wow64RevertWow64FsRedirection function to get around this. I haven't had much luck. Has anybody hit this problem?

TIA

Larry Peters
