How merge too big .txt files in only one?

Question

I have 7 files (approximately 4.7 GB each one) and I want to merge them into a single file.

I tried:

$ cat file1 file2 file3 ... > NewFile.txt

and I got this:

cat: stdout: File too large

Answer 1

"File too large" is a common error when trying to work with files greater than 4GB on a Fat32 filesystem.

If you're trying to combine the files on a Fat32 filesystem, you're going to have to need to combine them on a different drive formatted to exFat or NTFS (or for linux ex2/3/4).
