How to combine/merge/join all parts of a file?

[GAMEBOYADVANCETEMPORARY]

I downloaded Hollow Knight (Nintendo Switch) from a MEGA website but it is divided to 3 parts.

I want to play this game with either YuZu or Ryujinx but I must know how to combine/merge/join all these 3 parts to a single file so I can load it and start playing the game with either YuZu or Ryujinx.

There is no a readme file or a guide that teaches or shows me what to do.

I think that I should or need to use an application, program, software, tool or utility that does this job or task but if yes then what are names of such software?

I have already got both prod.keys and title.keys files and put them in the keys folder of YuZu and I also got the Nintendo Switch firmware and I will install it with YuZu.

I have already extracted them by using 7-Zip free software.

But each rar file contains only 1 folder with the same name and the same files.

I extracted them to the same directory.

When I extracted part 1 the extraction was done successfully without any error but when I extracted part 2 and part 3 the system asked me if to replace the files of part 1 with the files of part 2 or 3 and I clicked on the "No" button.

I don't think that YuZu and Ryujinx will be able to boot part 1 of the game without part 2 and part 3.

I think that the part 1 files are incomplete without part 2 and part 3.

U only extract the first one its a multi archive they extract all 3 in sequence

The contents in the folder after decompressing part 1 is the end product. You don't need to individually unrar and recombine the others.

If I don't have to extract part 2 and part 3 but only part 1 then for what part 1 and part 2 rar files exist at all if I have to ignore them?

 

[godreborn]

copy /b file.name.part1 + file.name.part2 + file.name.part3 final.file.name

 

[GAMEBOYADVANCETEMPORARY]

copy /b file.name.part1 + file.name.part2 + file.name.part3 final.file.name

Do I have to run this from an elevated command prompt?

 

[godreborn]

I don't remember, but I don't think so.

 

[GAMEBOYADVANCETEMPORARY]

I don't remember, but I don't think so.

I will try to run this from an elevated command prompt.

U don't do the copy command u extract the rar1 file only

 

[porkiewpyne]

If I don't have to extract part 2 and part 3 but only part 1 then for what part 1 and part 2 rar files exist at all if I have to ignore them?

Because the programs these days are smart enough to identify that you are decompressing part 1 of the file and will automatically search for part 2 etc to continue the process.

U can test this rename par 2 as 0 and see it error

 

[porkiewpyne]

Heck, he doesn't even need to rename the file. Just move part 2 and/or 3 to another directory and it will immediately be obvious

 

[GAMEBOYADVANCETEMPORARY]

Are you saying that if part 2 or part 3 is missing then I won't be able to extract part 1 at all?

 

[porkiewpyne]

Most programs would likely throw up a prompt for you to locate the part it failed to find once it reaches that point. There are options you can play around with to get it to ignore it but depending on what is in the compressed file, you might be able to salvage some data, or have it all be a useless corrupted file.

Many of the mainstream programs that I've used have some log of sorts while decompressing so you can check that out. Or simply try it out and see what happens. Or if you are really keen on doing things in a roundabout way, you could google it and sift through the results.
