If you're updating to LW 5.2.8 from an earlier version of LW then you may find that the only files that appear in LW's library are files that were being shared in earlier versions.
And files that were previously in My Library but weren't shared with the P2P network may no longer show in LW's library, so you'll need to add them again.

Or see the info below...

Clicking on the My Files icon will show the sidebar, where you can see LW's Library, Public Shared, Private Shared & whatever lists you've created. Files in Library aren't automatically shared with other users. Public Shared lists the files that you're sharing with the Gnutella network (so that they're available for download by other users). Private Shared lists the files that you aren't sharing with everyone but might share with friends if you use the Friends feature.

If dragging a folder, a dialog box will pop up asking you what categories you want to add - choose the file types that you want to add & then click add.

Highlight a block of files by clicking on a file & holding down the shift key until you reach the last file that you want to add. Click on Add to Library.

If you want your files to be shared with all other Gnutella users then those files must be in the Public Shared list.
