How to eliminate a troublesome warning from ModelSim

Hi, From the first day when I started using ModelSim, a troublesome warning from ModelSim accompanies me each time I use ModelSim.

I use Notepad++ to edit my *.vhd files, after recompiling the files, it always shows the following error report:

# Compile of *.vhd was successful. # ** Error: # g # Unable to replace existing ini file (xxx.mpf). File can not be renamed. # ** Error: unrecognized string explaining the reason # g # Unable to replace existing ini file (xxx.mpf). File can not be renamed. # ** Error: unrecognized string explaining the reason # $ # Unable to replace existing ini file (xxx.mpf). File can not be renamed.

Actually, I never touch or open the *.mpf files.

After several recompiling, I found many *.mpf files, here is a typical file name:

I always skip the error report.

What causes ModelSim to generate such an error report and how to avoid its creating?

Thank you.
