Saving config files with a question mark in the name?

[cj47]

Config files that start and end with a question mark. Since Windows doesn't allow this, how can one of these files be saved other than using another O/S to do so?

Also, On a SB510x modem, is there a file that controls speed where you can save the file and load it in another similar modem, then change the MAC and retain that speed?

firefox on windows just right click and select save as
rename file before clicking save

You can save them from the web interface? I thought they couldn't be changed? How about using Opera?
