I have been trying to uninstall and re-install Missing Sync with a clean install for a while and have yet to do so. I use the "Uninstall" supplied by the app, yet when a new install occurs, data from the prior install is still displayed in the log files. I deleted all those I could find, but I know there is some hidden place that more info exists. I know that OS X doesn't use a registry per se, but there must be something that is retaining this data. Help is appreciated.
Some apps put files in ~/Library/ or ~/Library/Application Support/ Also, a preference file in ~/Library/Preferences/
also, spotlight is your friend. usually only stuff in application support and a plist in preferences (both in the librarys)
Actually, spotlight in Leopard wont search these. You'll need to use the search in the finder window, and tell it to search System files.
