In the /data/database_name directory I have found a few files I

pretty big. I don't think it is safe to delete them, but can I do
something to decrease their size at least?
Here are those files and their sizes in MB:
1 #sql-2a91_cdf.frm
397 #sql-2a91_cdf.MYD
253 #sql-2a91_cdf.MYI
1 #sql-6094_2.frm
397 #sql-6094_2.MYD
1 #sql-6094_2.MYI
2 #sql-6094_2.TMD
Those are the files which contain the data in each table in your
MySQL databases. I think the .myd files contain the data, the .myi
files contain indexes, and the .frm files contain schema information.
In general, yes, files ending in .MY? are database files. These
particular files are actually temporary database files (because they
start with #sql-). They're created when you run an ALTER TABLE
command and are deleted when the procedure finishes. If you run SHOW
PROCESSLIST and don't see any active queries, then those files were
probably left over from a system crash and can be deleted.
