1. For fast & easy access, go to your LW Library window, select Saved Files folder & press the Explore button. Sample image here: Using Library Explore button to access downld folder (click on link) & the folder will open up for you.

After your downlds are 100% complete, LW moves them from the incomplete folder to the Saved Files folder. Only if you are sharing your Shared folder will this folder appear in the LW Library window.

The folders which will normally appear in your Library window are: incomplete folder, Saved Files folder, Shared folder if you're sharing it, & any other shared folders.

BTW on windows, the saved files folder is the same directory as your shared folder. After a time the files are moved into this folder.

2. I don't quite understand this question. (see above)

3. Go to LW's menu bar, Tools>Options>Sharing & that's where to add folders to share. BTW only the files listed in your Library window are those that are being shared. You can choose to share or not share those by right-clicking them. See How to Share Folders (click on link). You also have the option of sharing immediately downloaded files. You also have the option of sharing partially downloaded files, which helps speed up downlding for others.

4. Not sure why you'd have this problem. I think the files need to be mp3. I'm not sure the playlist will handle other formats but I might be wrong I can't remember. Sometimes if LW is busy uplding & downldling the media player can suffer so keep that in mind.

5. AFAIK it's simply "en" & queue as in kew (with a slight ee-ew in the sound.)
