Please explain: DB to File and File to DB consistancy check

What are some examples that would cause these to not match between file and database?

I doubt file corrupt is one of the reason.

Why would a file not delete?

db to file is to check if al files in the database still exist on the hard drive (are they still avaible)

file to db does the same , but it checks the files and see if they are avaible in the database


it happends sometimes that it is not able to delete files (mysql overload ?? , mysql buzzy and action got terminated ?? , any other reason that gives a read error ??)

if that happends , then that file will give a error when trying to download (if exist in database)

if the file was not able to add to the database as above example, then you will get a error when trying to get a file

it is a good thing to to use it when you move files betwean servers , so it checks if all files are pointed to the right server

hopley this explained it

There is a bug on the file check. When you move file and it times out. The file is partially moved already. So it is on both servers but the file to db check can't detect this and does not delete the other copy.
