Move attachments from database to file system
 

Hello, i'm wondering what exactly the option "move attachments from database to disk" does ? I mean, it's something that works "from now on", or it will migrate all my pre-existing attachments (300MB by far). Would be a risky thing to move all my attachments to filesystem ? I tend to believe it will improve the performance of my forum because an apache hit is "lighter" than a mysql hit ,but i'm quite doubtful to change something that works. So i'm wondering if should i do something before, if it's a risky thing, and such.

Thank you very much, have a nice day
Bye

See: Attachment Storage Type

The option move all the attachments (which are stored in the database) to the file system as files. You should not think of it as being "risky". It is a very easy and straightforward process.

I've moved 3000 attach for a total amount exceeding 270MB in less than a couple of minutes including the final db optimization, it has been really easy and straightforward, thank you very much.
