High DB File and Failure at the end of Indexing

[void]

Thanks for the USN Journal information.
Did you change this to 32768 KB? what was it before?

32768 KB is the default size.

I don't know where I canssee the journal.

Under Index in the main menu, click on Index Journal.

This will give you a good idea of the changes made to your system. (it's not complete, ~99% of changes should be listed)

I have 273 file change since yesterday evening.
The problem is actually, the indexing never stops and never ends now as I said in my previous comments. It is extremely slow now, it never ends.

Index menu -> Index Journal will give you a rough overview of the journal.
