for a start, your os is locked, i can't tell if the two upper items in the second images are archives, or iso's?
can't see any file suffix there, it does appear to be associated with winrar.
(i hate file assoc)
okay, in the first image, the (1) is a duplicate file.
either it was downloaded twice, or the dl'd archive was expanded twice, and didn't overwrite the last attempt, but renamed the dupe instead.
i'm not sure you're doing anything wrong, if the two item in the second image are iso's (associated to winrar as iso is an archive container) and NOT compressed archive.
if they are archives still, using rar/7z, target the file expansion to another directory, to avoid any possible overwrites and/or dupes, you'll be able to track filenames as well.
all the best, others may chip-in soon.
