Go to Tools -> Options -> Shared & press Add button & browse to where the link suggested: C:\Documents & Settings\username\My Documents\FrostWire\Saved or Shared

Other than that, use your computer search function & type in extension of one of the files that's missing. Example: .mp3 & it should list all music files on computer. Scroll through each one until you find the location where your missing files are. Then add that folder to share.

Thank you so much for the advice. I would like to apologize if the question was posted in the wrong position.

Again, thanks for the reply and advice.
