I have a concern with the use of WinZip command line VS WinZip command line utility, such WinZip.exe VS WZZip.exe and WZUnzip.exe. I execute those from .NET by using the process approach. I would like to know if someone knows if there could be a conflict if WinZip.exe is executing for a second or two for example, while WZZip.exe is being executed on the same server from another process. Could there be a chance that if WinZip.exe is executing, during that time, this could interfere with the good running of the WZZip.exe command line utility?

Because, as far as I know, they both use the same core engine. Is it built to be multi threaded?
