directiories Nuvi 200w, help!

Here is outline for custom pois and loading to gps http://www.poi-factory.com/node/25721 .You will have to go to your favorites and delete them.Tools,my data and delete favorites.Not sure but you may have to delete one at a time for the 200.

Other methods.You could do a hard reset and delete all the favorites at one time and manually put favorites back .You could also connect gps to computer and go to Extra Poi Editor http://turboccc.wikispaces.com/Extra_POI_Editor and under file select Open Garmin Favorites.Once loaded delete the ones you don't want.Then go back to file and select Save to Garmin Favorites.

Edit.Make sure to copy the current.gpx file.Connect unit to computer and go to Garmin drive.Garmin folder then gpx folder.You will see current.gpx there.Good idea to make copy of the complete garmin folder in case you have problems down the road one day.

Please click on these two links by holding down the Shift key when you left click them and follow their instructions

You will get a manual, make sure some settings on your computer are correct for later POI loading and do a full backup.

With a full backup, you can recover from mistakes and feel better about following some instrustions like deleting favorites. If you did not like the results, you can return to the state of your backup.

I am a bit leery that POILoader is what caused the problem with your favorites - but strange things do happen.

More likely, a gpx file was pasted to 200w drive, then when 200w was started up it processed the gpx file as a favorites import, similar to a temp.gpx file is processed.

and would explain what happened. Hope OP will tell us what he finds because he did imply that he used POILoader.
