Why are .exe files with ".upg" suffix created?

Question

Why are .exe files with ".upg" suffix created? After doing Version Check, there's a file with a ".upg" suffix in the .\bin directory and the .exe file has not actually been overwritten. For example: A .\Circ\bin\circ.exe.upg file has been created -- but the previous .\circ.exe is also still present.

Answer

When Version Check is invoked from a particular module, such as Circulation, the .\bin\circ.exe file is unable to overwrite itself (since it is in use), so the "circ.exe.upg" is created. When the Circulation client is closed, the circ.exe.upg is renamed to circ.exe.
