Extensions problem report, again.
Thanks for RAR5 all 2017 and 2018 (also 2008-02 and 2008-03 to be precise), but I checked some old files and see more.
Example, if you have a ZIP file, named as RAR, when you open it, WinRAR will read it with "RAR algorhythm", not ZIP, that's why some files were missing. However, 7-Zip somehow read the archive as a whole, then detects its algorhythm and show it, without caring about extensions.
Just try renaming some "actual RAR files" to ZIP, open with WinRar and see what happens, xD. (Not with 7z though, WinRAR can still read the contents, or Elessey just store them as an archive file and not compressing anything. So basically, it won't affect files I mentioned as 7z down below.)
The reason why this happened, probably because of this:
Done talking, here's the list:
"osu!"
2007-10: Solid 7z.
2008-09: Solid 7z.
2009 Mar, Apr, Jul, Oct: Solid 7z.
2010 Jan, Jul: Solid 7z.
2016 Mar, Apr: Deflate ZIP.
2016-06: Solid 7z.
"osu!taiko"
2010-11: Solid 7z.
2011-01: Deflate ZIP.
2012-04: Solid 7z.
2013-05: Solid 7z.
The rest are RAR 4.0
I mention this because I use Linux when I want to "mass-extracting" them, if you want to unzip, you use "unzip", same for rar "unrar", and sometimes it show errors "20ab-xy is not a *.rar file"... which is pretty annoying.
And another error: Entire 2018 of Taiko gone wrong.
The archive is corrupted, unexpected end, corrupt headers, empty archive (although still took lots of space), and variety kind of extensions: Jan->May: RAR4; Jun, Sep & Dec: RAR5; Jul: Solid 7z; Aug: 7z; Oct & Nov: Deflate ZIP.
Sorry, my bad, I downloaded the latest torrent files, and it works, also
