Periodic cleaning up for files created by SQL filestream.

I added a filestream column in one of the sql tables.

I am storing word documents into that column - from the web using ASP.net functions.

I am able to store and retrieve the files from the filestream column. My concern is that, every time I add or modify the files, it creates lots of physical files in the associated folder. Is there a best way to periodically cleanup theose files (that were created as part of the filestream).  

I found few methods from my search. But most of them are unclear.

Thanks,

RP

Just to be clear, where are these files, and is there a reason for not cleaning them up at the end of "store into DB"?

The files are automatically created by the SQL server.

They are stored on the same folder where the database files are stored (ProgramFiles\MicrosoftSQLServer\MSSQL10.MSSQLSERVER\MSSQL\Data\[specific database name]).

Inside the specific database sub folder, there is one subfolder with the name $FSLOG, a file with the name filestream.hdr and several other subfolders (they are all automatically created as part of the filestream updates).

Regarding cleaning up - that is my main concern. We cannot simply delete these files. We need to check if the are old enough to be deleted. I believe SQL has a command. But I am not clear whether we need to run that command manually. If so, when we need to run?

Thanks,

Resolved. The SQL server does this automatically and so no action needed by the user unless there are some space issues in the database.
