Shareaza

I have just realized there are two entry on the context menu for preview, see capture.
(in French language, the first entry is not translated)

Yes I saw that the first is for the file and the second for the partial file ... but the function is the same :p

Delete one ? :-"

Preview - copy already downloaded parts of the file to new one and open it directly or by using one of available previewers (see "Shareaza Preview Plugin");
Preview Partial - open .partial-file as is.
