What is the behavior of lnk files?

I access a files which name is "abc.doc", no doubt a lnk file "abc.doc.lnk" shows up. Few minutes or hours later I access "abc.doc" again, what will happen then? "abc.doc.lnk" still or another lnk file "abc.doc (2).lnk" show up???

Yesterday I analyzed artifacts of an evidence which operating system is Windows XP SP3. When I took a look at "Recent folders", some lnk files look strange. Under what circumstances could so many same lnk files show up as below? You guys could take a look at the timestamps of file that those lnk files pointing to. The same CreationDate and these lnk files do point to the same file "其它各類所得.xlsx".

I'd appreciate your providing any information you have. Thanks a lot.
