[Wine] WINEPREFIX ?

[crow_se]

I have seen posts regarding WINEPREFIX so that Windows programs can be installed elsewhere than in the default .wine/drive_c/... folder.
I have 2 or 3 Windows programs in the default folders which I run under Wine, and another program (Serif PagePlus 11) also in the default folder that does not run and I want to uninstall. Wine uninstall does not work for this program. I gather I can uninstall by deleting the .wine folder, but that will delete the other programs as well. I also gather that by the use of WINEPREFIX a windows program can be installed elsewhere than in .wine, and then deleting and recreating .wine will have no affect on such an installation. If this is true, could I move these programs out of .wine to another folder by moving from .wine/drive_c/Program Files/... to another folder setup by wineprefixcreate and modifying the program calls to take this WINPREFIX setup into account ?
