UD_EX_FILTER and UD_IN_FILTER why do we need to include

[jayramona]

Why does the default script command UD_IN specifically include windows winnt ntuser etc?

I just don't understand why we need to specifically include locations. I assumed that all locations would be included unless excluded.

Thanks,

Jay

The default set up is as follows:

1. Temporary files are excluded in any case
2. GUI processes regular files except system files
3. boot time script processes system files heavily locked during regular usage

You can change this to only process data files or disks using the GUI and the boot time script processes the system disk entirely.

Thanks for the explanation.

Is the master file table included in this default boot defragmentation?
It doesn't seem to be on my system.

[Dmitri Arkhangelski]

The first 16 clusters of the master file table are immovable, so, formally, you cannot defragment it. That's why we have added the MFT optimization to the program. To optimize MFT on drive C:, for instance, you have to add the following line to the boot time script:

udefrag --optimize-mft c:

It will quickly optimize the table and then go to the next instruction of the script, if any.
