Browser Cache Size and Using CCleaner

Posted by cotojo on May 15, 2007

Browsers cache settings  give your pc the ability to store
frequently visited web pages and also checks for newer web
pages when you navigate to those sites.

Most computers cache setting is left at the default
setting, which can be anything from 250MB to over 1024MB,
which generally speaking is far too high.  You can safely
reduce this to as little as 10 – 20MB.  You may find that
you frequently download large files, for example a file of
50MB, so you would need to adjust you cache size to 60MB so
that if the download is interrupted it will pick up from
where it left off using the cache memory rather than
starting over again.

To adjust the IE cache size:
Start Internet Explorer
Select Tools | Internet Options | General tab
Under Temporary Internet Files click the Settings button.
In the box for the amount of disk space to use, enter a
value between 25 and 50 megabytes.
Click OK to accept the changes.

To adjust the Netscape Navigator cache size:
Start Netscape Navigator
Select Edit | Preferences | Advanced | Cache.
In the box for Disk Cache, enter a value between 5120 and
51200 kilobytes.
Click OK to accept the changes.

By making this simple adjustment, you will save lots of
hard drive space for better uses and it will improve the
overall performance of Internet Explorer.

If you want to have a large cache size, then I recommend
that you clean your cache out regularly.  I do a lot of
browsing and clean mine several times a day, but rather
than go through Internet Properties and start clicking on
various buttons I use ccleaner available for free from

CCleaner is a freeware system optimization and privacy
tool. It removes unused files from your system – allowing
Windows to run faster and freeing up valuable hard disk
space by automatically cleaning the cache when run. It also
cleans traces of your online activities such as your
Internet history. It also only takes a few seconds to run
and remove these unwanted files from your pc.

I set mine up as follows:
Click on the Cleaner Tab on the left and under Windows I
tick all boxes in Internet Explorer, Windows Explorer and
System.  Under Advanced tick only the first 2 boxes.  Then
click on the Applications tab and tick all.

Issues tab:
Unless you are competent at dealing with the registry then
leave this one alone and DO NOT run it.

If you wish to run the Issues to clean the Registry, carry
out the following first:

Backup your Registry. Go to Start, Run and type in regedit
click on OK and the Registry Editor will then open. Go to
the top Tabs and click on File, scroll down until you see
Export, left click it and this will open Export Registry
File window. Save this file to your desktop and in the File
Name box enter Registry Backup File. Click on Save and it
should now be on your desktop. Verify the file is a good
copy, in the Registry Editor window click on File, select
Import, in new panel where it says ‘Look in’ select desktop
and then click on your saved file then click ‘Open’. Once
it says it has been read in successfully, you have a good

Now if you find that some programs are no longer running
in the way that they should, restore your Registry as
detailed above. CCleaner will also create backup copies of
your Registry and I suggest that if you do choose to run
the Registry Issues untick all of the boxes and tick one
box at a time and run each one separately.

Tools tab: 
Here you will find a list of Uninstall options to remove
programs from your pc, use with caution.  I prefer to use
the Add/Remove function or the programs own uninstaller.

Lists all programs that are set to run when you boot up,
if you are unsure about deleting any of these then leave it
as it is.

Options tab:
Settings – Choose your language, untick Run CCleaner when
the computer starts, tick the next 3 boxes, then look at
the Secure Deletion, tick the radio button ‘Secure file
deletion (Slower) and set it to NSA (7 passes)

Cookies – entirely up to the individual, but I don’t save
any cookies.

Custom – You can drag and drop files or folders into the
window or browse for them and on the next run they will be
securely deleted.

Advanced – Untick boxes 1-3 tick all others.

Finally click on the Cleaner tab on the left and you have
the option to Analyze or Run Cleaner. When you are
comfortable using this program you won’t use Analyze, but
initially do use it to see what can be deleted and the
approximate size of files to be deleted.

This will remove any saved passwords and usernames that
you have, so make sure that you have a copy of them all
before proceeding to clean.

Open a text document, enter the URL, username and
password, save this to floppy, external drive or print it
off.  Do NOT save this text file to your hard drive.

There is an excellent program for saving your passwords
etc available from
I will cover this in more detail another time.

As always, back-up your system or create a restore point
before making any changes.

To your safety and security online
