Question

I have a .sql file created in Linux using:

mysqldump --opt db_name | gzip > backup_file_name.sql

I need to use it in Windows. 7-zip can open it, but when extracting, it says “Data Error in backup_file_name.sql. File is Broken.” I also tried http://www.gzip.org/#exe and I can’t get it to work. Any ideas?

Answer 1

I think the problem is that you’re trying to open a .gz file, which is just a compressed single file, while 7-zip is designed for compressed archives like .tar.gz.

Try downloading gzip for Windows, then run:

gzip -d backup_file_name.sql.gz
