Trouble emailing songs

[Johno7777777]

Hello i'm new and not too bright using my PC . I have no trouble searching for and downloading songs but having trouble sending a particular song (s) to friends who for varying reasons do not have Lime Wire .
Last night i was succesfull in sending a few songs by email and think it was from Lime Wire Saved folder displayed on the left side of library page , this morning there was no Lime Wire Saved folder . What have i done wrong?? Only thing i can think of is my computer anti virus detecteda virus and quarantined it . Did it wipe out my Saved Lime Wire folder ??
Looking for some help please in laymans talk
