/enqueue is a way for a script to include operations in the queue that would otherwise be performed immediately.
If you use for example the /ren command then the operation is performed  immediately (not added to the queue), now depending on the situation  this may not give the desired result.
Take a look at this code, since the /ren command is performed  immediately the rename operation takes place before the files are  transferred. FAILURE..
	Code:
	/selectall
/transfer selected
/ren "%p%f" "%p%f.downloaded"
/start
 To get the desired result we need to enqueue the /ren command like this
	Code:
	/selectall
/transfer selected
/enqueue /ren "%p%f" "%p%f.downloaded"
/start
 The reason I used 
/transfer selected above and not 
/queue selected is because the 
/queue selected command adds the items to the end of the queue where-as the 
/transfer selected command inserts the items in-line. This is somewhat confusing, I know
