It's a multi-part zip, you DL them all, then just unpack the 1st one and it'll find/include the others.
Sorry to keep this going; but I can't unpack the .001. I get an error every time. Winrar says it's corrupted and 7Zip says it can't open it as an archive.
This thread is plagued by similar questions to mine... I've never messed with split files before; from what I can tell I'm supposed to select all of them and extract, or just extract the .001 file. Neither method is working; I always get an error.
I'd rather not bother more users on this thread, but I can't find anything on the internet specifically about what to do with these files when they're corrupted like this. Maybe I'm being dumb and overthinking this. I'd be willing to accept that. But a lot of users on here make it seem much simpler than what I'm struggling with; and after sifting through several searches and just straight up reading pages of this thread, I just want to ask for help again.
EDIT: Instead of deleting this, I want to keep it up, as it's a fix for others downloading via the split and can hopefully help. I'm not removing the wording up top because it should contain a lot of tag words for others searching that are having issues.
Depending on the download links you're downloading parts from, they will have different formats in the names. Some of the file/part names just use spaces, others underscores, and some have brackets around the modder's name. MAKE SURE that every file has the same name when trying to extract. Put all 8 parts in one folder, select all of them, and click "Extract Here". This should work; I didn't think of this fix before because I assumed they'd all work together, though like I say in my reasoning up top, I knew I had to be overthinking things somehow.
Anyways, in short; to those using the parts, make sure to double check that every part has the same name. This will solve some of the header/corrupted errors, though I'm sure it won't fix all of them.
