Hi All,

Could anyone tell me where i can get more explanation on the following files in each disks?

Directory DISK$PATCH:[000000]
BACKUP.SYS;1 BADBLK.SYS;1 BADLOG.SYS;1 BITMAP.SYS;1
CONTIN.SYS;1 CORIMG.SYS;1 DKA100.SYS;1 INDEXF.SYS;1
SECURITY.SYS;1 VOLSET.SYS;1

Regards,
Sentosa

Those all look like standard files except DKA100.SYS

Sentosa,

.. and I guess you can confirm Ian's statement by looking
DIR DISK$PATCH:[000000]*.SYS /DATE

I expect all to reflect the disk INIT time, except DKA100.
How big is that file? If > 0 then
Can you TYPE it ? (guess not)
Does DUMP show anything recognisable?
(I have seen BACKUP savesets from other disks/systems named similarly, but that is a VERY wild guess!)

More info MIGHT lead to more precise answers (but that is not a promise!)

hth

Proost.

Have one on me.

Sentosa,

Most of those files belong to OpenVMS and should be left alone. If you want to know the details of what they're for, find a copy of "Vms File System Internals" by Kirby McCoy.
