When attempting to access a file retrieved from an FTP server, you may see -408 or -417 errors
R9.3d to R10.4d (may affect previous versions)
Resolved In Version:
If your PAC Control strategy uses a communication handle to open an FTP session to retrieve a file from a remote FTP server, after the file is saved to the computer, when the PAC Control strategy attempts to access the file (for example, with a file communication handle to write to the file), you may see error messages like "error during file access" (-408) or "cannot open file" (-417). This is because SoftPAC sets the hidden attribute when it saves the file on your local PC.
Manually remove the hidden file attribute from the retrieved files through Windows File Explorer.
