Text file in the mdbdata folder?

[chubilly]

there are a bunch of text files in the mdbdata folder and each of them is about 5120kb in size. Can anyone tell me what they are and if I can delete them without causing any problems to the exchange as they are taking too much space in my server. I would like to delete them if they can be deleted.

Ex:
Name: Size Type
res1 5120kb text document
res2 5120kb text document
ED0000001 5120kb text document
ED0000002 5120kb text document
etc.....

DON'T DELETE THEM !!!!

The res1 and res2 files are used by Exchange to reserve enough space for 2 log files. These get used when the drive that the log files are stored on fills up. It then uses these file logs to commit any outstanding transactions while it dismounts the store.

The other files are the log files. Exchange writes all transactions to the log files before committing them to the actual databases (for disaster recovery). If your drive with your log files is filling up with log files you need to perform a Full Backup (Flush Exchange Logs) which will delete all committed log files during the backup process.

You could enable circular logging, which will overwrite the oldest log files ...... not a good idea as this causes problems in the event of a server failure and also stops you being able to perform Incremental and Differential backups.

The system was generated one log file every minute last week and I ran out of space. I don't know why the backup does not clear it either. It racked up about 40gig of log files. I had to manually delete the transaction log files and now the backup will not complete.
How do I resolve this problem now?
Please advice.
Thanks in advance.

Get the person who set ip up in there and like ACraib said, don't mess with the log unless you know what you are doing!
How you resolve it now, also as said: enable circular logging

Marcs41,
Thanks for your response.
I have enabled circular logging, restarted the machine.
It seems fine now.
Can I disable circular logging so it will start to get the transaction log again?
Please advice and thanks.

The logging will be there, but as explained by ACraib already, it will overwrite itselef, the oldest first.
If you want or need the logs, copy them off the server.
