Does zgrep unzip a gzip file and make a temporary copy before searching or does it search directly on the compressed file?
This source of zgrep uncompresses the file with zcat and pipes the result to grep.
So, no, it does not use a temporary file, but yes, it decompresses (but not fully) before searching.

Error when running this command, i think the command is clear to get the idea.
cp file.txt /folder/*/*/*/file.txt
You need a loop to do that:
for dir in /folder/*/*/*/; do cp file.txt "$dir"; done

I need to extract a multi part rar archive in the form of archive_1.exe archive_2.rar archive_3.rar. How can I do this in linux?
I have tried unrar and 7z but unrar x archive_1.exe is extracting files with the reverse path format (eg. \file\dir) and 7z is unable to extract beyond the first file.
Any suggestions are welcome!
cd /path/to/your/download
unrar x filename.of.part1.rar
