Our company is a service provider for scientific organizations, we
host a lot of scientific sites, dynamic and static on LAMP.
Now one of the users send me a zipped directory with *.frm, *.MYD and
*.MYI files and asks me to place them in the MySQL directory.
I have given him access to his database via PHPMyAdmin, I once
convinced him to give me a file with SQL statements (tabel creates and
data inserts), but no he persists on sending those *.MYD, *.frm and
*.MYI files. Is this a normal way of working ? Are there any risks to
copying that directory to /var/lib/mysql/ ? Risks as in malicious or
just because of different mysql versions, ... ?

thanx,

J
