Not as far as I know. For quite a while if you downlded a file you already had sitting in your downld folder, LW would warn you asking if you wanted to rewrite over the other version. So ... they brought in an option where you can rename the file / change its downld location. Or the Download As ... option. Or are you refering to the LW Library. That option was taken out because people had too many problems using it. It seemed to cause more problems than benefits.
BTW any version older than 4 is bad for the network. There's a reason they don't make them still available. And some of the earlier versions will either get automatically banned by some LW or other gnutella hosts, or will if it behaves improperly which is why those versions were taken out of circulation. Ask Only A Hobo what banned host means when LW does it automatically. It's like using a steam train in a pollution free neighborhood (no petroleum vehicles allowed, etc.
) It's about being responsible.
