I noticed that I had a project named RemoteSystemTempFiles which I never have created. After googling it seems to be plugin feature on eclipse, but didn\'t got any other idea of
I would like to add that there might be situations in which you actually do not have the RSE UI plug-ins installed. However, the RemoteSystemTempFiles will still appear in your search results :-(
Example: For instance you have used an earlier version of Eclipse, including the RSE UI plug-ins. Later you have installed a newer version, probably to a different folder, but reusing the old workspace (via conversion). This time you have not installed the RSE UI plug-ins so your IDE has no option about this damn thing (which in fact is a very nice tool while working on Remote Systems).
However, despite the fact it doesn't have the plug-ins installed, Eclipse will still update/use that old/existent RemoteSystemTempFiles repository/container/whatever and thus it will always appear in your Search Results. Pretty annoying, I know!
The solution is quite simple:
Help -> Install New Software, then choose the "http://download.eclipse.org/releases/[your-version-here]", then enter remote in the filter box. Remote System Explorer End-User Runtime & co. Probably the plug-ins could be found within the General Purpose Tools group, but this group may change from one edition/platform to otherWindow -> Preferences then select the General -> Startup and Shutdown and uncheck the RSE UI. Now it is disabled even in Search Results. Additionally you may select Window -> Preferences then Remote Systems -> File Cache and click Clear Cached Files.That would do the trick - hopefully ;-)
