Help with some files

I just downloaded all of the files from this site and extracted all of them except

The Sims 4 - Cats & Dogs\EP04\ClientFullBuild1.package
The Sims 4 - Jungle Adventure\Data\Client\ClientDeltaBuild4.package

I think these files are corrupted on my download so if anyone could upload them it would be very helpful.

If you still have .rar files you can check them in your torrent client. After it downloads missing parts just extract those files.

When I try to extract them they give error, that's why i thought they were corrupt.

That's why I told you to check them in your torrent client. Right click, check files/force check or something similar, depends on your torrent client.

I'm using qBittorrent. After checking the torrents they said errored after quick googling i found out it has to do with I/O. I think my harddrive has some problems.
I would download it all again but my internet speed is not that good.

Are you sure you didn't move/delete .rar file you've downloaded? Because if you did, qBittorrent, and any other torrent client, will give you some error.

No I'm sure.

I think I won't be needing "The Sims 4 - Jungle Adventure\Data\Client\ClientDeltaBuild4.package" this file if I'm gonna merge it anyway because of the other dlc's right ?

Yup. Most up-to-date "Data\Client\ClientDeltaBuild4.package" is in "The Sims 4 - Seasons.rar".
