used disk space dramatically increased

R

Rien

Hello,

- If I look at the place used of the partition C (by working station
icon -> R-click on C: -> properties), I find for example 10 GB.

- If I look at the total of the sizes of the files and folders inside
the same partition C: (by opening C: and selecting all the files of the
root, then clicD -> properties), I have then only 6 GB!

Where are the other bytes gone ??
*Of course I do that on an administrator account, and I parameterized
explorer to show the hidden files and the system files*

In fact I always saw a difference, on several PC which I used. But I've
just partitionned the HDD into C: and D: to make backups easier, and
since then the difference is bigger (30%) than before the operation, and
that's worrying me. Is there any link with this mysterious difference of
size?

Thank you

Are you using Norton Protected Storage?

To investigate how you are using hard disk space you need to make sure
that
you can see all files. Go to Start, Control Panel, Folder Options, View,
Advanced Settings and verify that the box before "Show hidden files and
folders" is checked and "Hide protected operating system files " is
unchecked. You may need to scroll down to see the second item. You
should
also make certain that the box before "Hide extensions for known file
types"
is not checked. Next in Windows Explorer make sure View, Details is
selected
and then select View, Choose Details and check before Name, Type, Total
Size, and Free Space.

You still will not see the System Volume Information folder.
How to Gain Access to the System Volume Information Folder

FileSize -a useful tool for use with Windows Explorer when investigating
how
disk space is being used.

The download link is not obvious. Click the here in the two sentences of
the
web page accessed through the link above. "I can't count the number of
times
someone has asked for this. So here is a module you can install that
shows a
Folder Size column in Explorer."

To increase you free space on your E partition select Start, All
Programs,
Accessories, System Tools, Disk CleanUp, More Options, System Restore
and
remove all but the latest System Restore points? Restore points can be
quite
large.

You should use Disk CleanUp regularly to Empty your Recycle Bin and
Remove Temporary Internet Files. Whenever you remove redundant files you
should always run Disk Defragmenter by selecting Start, All Programs,
Accessories, System Tools, Disk Defragmenter.

It is likely that an allocation of 12% has been made to System Restore
on
your C partition which is over generous. I would reduce it to 700 mb.
Right
click your My Computer icon on the Desktop and select System Restore.
Place the cursor on your C drive select Settings but this time find the
slider and drag it to the left until it reads 700 mb and exit. When you
get
to the Settings screen click on Apply and OK and exit.

If your hard drive is formatted as NTFS another potential gain arises
with
your operating system on your C drive. In the Windows Directory of your
C partition you will have some Uninstall folders in your Windows folder
typically: $NtServicePackUninstall$ and $NtUninstallKB282010$ etc.

These files may be compressed or not compressed. If compressed the
text of the folder name appears in blue characters. If not compressed
you can compress them. Right click on each folder and select Properties,
General, Advanced and check the box before Compress contents to
save Disk Space. On the General Tab you can see the amount gained
by deducting the size on disk from the size. Folder compression is
only an option on a NTFS formatted drive / partition.

Another default setting on a large drive which could be wasteful is that
for
temporary internet files especially if you do not store offline copies
on
disk. The default allocation is 3% of drive. Depending on your attitude
to
offline copies you could reduce this to 1% or 2%. In Internet Explorer
select Tools, Internet Options, General, Temporary Internet Files,
Settings
to make the change. At the same time look at the number of days history
is held.

The default allocation for the Recycle Bin is 10 % of drive. On your
drive
5% should be sufficient. In Windows Explorer place the cursor on your
Recycle Bin, right click and select Properties, Global and move the
slider
from 10% to 5%.

Hello,

It was indeed the system volume information. Il followed the procedure
on the MS support web site and I saw a 4 GB directory !
The solution to make it diappear is to suspend the system restauration
by "system properties" and reboot.
So I could make my backup image faster and shorter.

Thank you Kemco for your advice.

By the way I still have one question more : why is this directory so
well hidden ? And would it be useful to replace the rights on "system
volume information" as they were before (access only for SYSTEM) ?
Thank you

Hello
Thank you for those explanations.
They're quite comprehensive and it's useful to sum up the different
possibilities.
I got a post from another person who warned me about the "system volume
information" and it was the good thing. You can read my answer to that
post just before for further details.
Thank you anyway & good by

Interesting. I have never tried out the suggestions in KB 308421.
It doesn't only enable opening of the System Volume Folder for the
folder selected but also other Volume Information Folders on
other partitions / drives.

Thanks for the pointer.

The directory is hidden to keep the average user from messing with it and
thereby messing it up. No functional reason to change permissions back
other than per my previous point.

Not a good idea to turn off System restore just for backup purposes. A
better approach is to manage System Restore. By default is uses 12% of the
drive which on modern drives can be a lot of space, and way too much for
System Restore. SR is only good out to about one or two weeks. With all
the other changes occurring in a system, that are not monitored by system
restore, going back too far will result in inconsistencies. Best to limit
the size allocated to system restore so that it keeps only about one to two
weeks worth of restore points. This is done in the same place were you
turned it off. Turn off system restore on data only volumes.

See Bert Kinney's System Restore page for info on SR and for tips on keeping
it healthy.
