Removing My Money from the System
You can remove My Money 2.0 through the Control Panel in the Start Menu on Windows, by removing the MyMoney.app application bundle on OS X, or by removing the MyMoney folder on Linux.
Removing MyMoney won't remove your system settings, extensions or other add-ons. This data is stored in your profile folder, which is located in one of the following locations depending on your operating system:
Windows Vista | Users\<UserName>\AppData\Roaming\.mymoney |
Windows 2000, XP, Server 2003 | Documents and Settings\<UserName>\Application Data\.mymoney |
Windows NT | WINNT\Profiles\<UserName>\Application Data\.mymoney |
Mac OS X | ~\.mymoney |
Linux and Unix systems | ~\.mymoney |
Any version of My Money that you install will continue to use the data from this profile folder.
