What is C:\$Extend\$UsnJrnl:$J:$DATA

[Guest _Who]

60 C:\$Extend\$UsnJrnl:$J:$DATA

1 C:\$LogFile

1 C:\$Bitmap

1 C:\$Boot

1 C:\$MFTMirr

1 C:\$MFT::$BITMAP

 

 

Should I be concerned that C:\$Extend\$UsnJrnl:$J:$DATA has 60 fragments?

And that the others have 1?

 

If so, how can I defrag them.

 

 

Thanks

I would be much more concerned about knowing which program created these

folders. I would also wonder what purpose the contents of the folders

serve. There are problably lots of other things about them which are cause

for concern. The last of these things is whether they need defragmentation

or not.

I assumed they were system files.

When I show the folder C:/ they don't show.

Got any suggestions?

 

thanks

They're part of the NTFS structure, the $USN Journal is not read or used

by Windows but the others are essential to the health and proper

operation of the NTFS file system.

So it would appear that the fact that $USN Journal is fragmented is not

important.

The others each have one fragment. Is that worrisome?

I wouldn't bother too much with it. Windows doesn't use this but other

applications use it to keep track of file changes, by default this is

disabled on Windows XP installations but any application can turn it on

if it needs it.

 

Change Journals

http://msdn.microsoft.com/en-us/library/aa363798.aspx

 

On Windows 2000 this journal was enabled by default and the file system

driver (ntfs.sys) could not overcome corruption in this file, although

infrequent, damage to this file had a pesky little side effect of

rendering the disk unreadable and unmountable. Changes were made to the

Windows XP file system driver and errors in the journal are ignored by

the driver and the disk can be mounted and read even when the journal is

corrupted.

Guess there are hidden and REALY HIDDEN files'

The following produces some names but not the ones we've discussed.

 

dir /s/a:h C:\*$*
