WAMP server. Very large data directory in MySQL?

Question

I have problem with wammp server. In directory "..\WampServer\bin\mysql\mysql5.5.8\data" was created files with very large size. Full size of this directory is 50GB. What is these files? How can I fix this problem?

The names of files are:

mysql-bin.000001
mysql-bin.000002
................
mysql-bin.000227

The size of all files is 49GB

Thanks in advance!

By default whenever you make a change to a MySQL database it creates a log of the query and stores it in a file simlare to mysql-bin.000001. The MySQL database does this so that you can recover or replicate a database. Most applications this is a good things to have enabled just like doing regular backups.

If you want to disable MySQL from creating these binary logs:

1. Open my.ini
2. Search for this line log-bin=mysql-bin
3. Comment this line out by adding a hash mark: # log-bin=mysql-bin
4. Save and restart the MySQL database

You can now safely delete these files from that directory.
