Tips to Save Space on Your Hard Drive (Hard Disk)
With multi-terabyte drives gaining prevalence in the bays of our PCs, a lack of hard drive space is less of an issue these days; however, it seems no matter how big the drives get, we still manage to eventually fill them. In this guide, you’ll learn ten top tips to save space on your hard drive.
1. Uninstall Unneccessary Software Programs
Although it’s an obvious tip to start with, some serious space can be saved by uninstalling unneccessary applications. You have three options:
1. Scan the list of installed programs manually (Click the Start button, click Control Panel, and click Add/Remove programs — Uninstall a program.)
2. Use Revo Uninstaller to completely remove software and its traces.
3. Use the PC Decrapifier to remove typical “bloatware” applications from your PC (works best with new brand-name PCs.)
Not sure what to uninstall? Ask in the forums.
2. Search for Duplicate Files
Over time, you may accumulate duplicate files on your PC. Use a program like Easy Duplicate Finder to locate and remove these files.
3. Clear up old System Restore Points
System restore points are very useful but can take a lot of space on your drive. If you want to save space in a pinch, read this guide and learn how to remove all but the last system restore point.
4. Turn of Memory Dump Files
If you maintain your own PC, and don’t need to take it to a store when something goes wrong, you can turn off memory dump files. If you have system problems and need to analyze dump files, you can always turn them back on again.
5. Change Personal Folder Locations
All recent versions of Windows utilize the (My) Documents file structure. This means that all your personal files are:
* Saved on your operating system’s drive and can be lost if your PC is infected with malware.
* Taking up space on your operating system’s drive and can fill it quickly.
You can change the location of your personal files in (my) documents to a different drive (or partition of a drive); due to the issues listed above, this is something I highly recommend.
6. Backup Files Remotely or on Alternative Storage Media
I highly recommend you back up your files on an automated schedule. I also recommend you back up files that are used less on alternative storage media (Optical media, external hard drives, off site servers etc.) I recommend any of the following programs:
* Mozy Online Backup
* GFI Backup
* EASEUS Todo Backup
* Ashampoo Burning Studio
7. Use the Disk Clean Up Tool
The disk cleanup tool that comes with Windows is a useful tool that searches for junk files, unused installation files, temporary files etc. To get to the Disk Clean up tool:
1. Go to Computer.
2. Right click and drive and click Properties.
3. Click the Disk Cleanup button.
4. Select what you want to clean up and click OK.
If you’d like to add a handy “Clean Disk” shortcut to the context menu of the disk drive, follow this guide.
8. Use NTFS Compression to Compress a Complete Drive/Partition
NTFS is the name of a file system used in Microsoft Windows and is, for now, the standard file system for modern drives. Microsoft has a tool that compresses less used files on an entire drive.
If you want to compress a whole drive (and potentially save a lot of space), follow this guide.
Note: I don’t recommend you compress the drive (usually C:\) on which your operating system is stored.
Note 2: To find out the file system of your drive:
1. Go to Computer.
2. Right click and drive and click Properties.
3. Look for NTFS next to the File system label.
9. Compress (Zip) Less-frequently Used Files
You can compress files on a file-by-file (or folder-by-folder basis.) If you’re looking for a good compression program, check this Winzip alternatives post.
Note: some files compress better than others. For example: an MP3 or JPEG file is already highly compressed and wont reduce, in size, much (if at all) when zipped.
10. Take your Time During Program Installation
When you install software, take time to see exactly what you’re installing. A lot of the time, you can save a ton of space by selectively installing only the components you’ll need.
For example, when installing Microsoft Office, you can Customize your installation:
Now you have the option to only install the programs you really need (you can always install the other programs later.)
With Synergy Use Your Keyboard and Mouse on More than One Computer
Use Your Keyboard and Mouse on More than One Computer with Synergy
Recently, Thomas reviewed a program called InputDirector, which lets you use a single keyboard and mouse across multiple computers. For some time, I've been using Synergy, which does the same thing. In this review, I show you the features of Syngery and show you how to use it.
| Windows Guides' Rating | User Rating | Compatible with | System |
  4 out of 5 | Note: There is a rating embedded within this post, please visit this post to rate it. |    |   |
 PROS: Lightweight, does what it claims, can be very useful for Home Theater PC setups as well as multi-PC offices etc.CONS: Can be a little difficult to get working as you expect it to. Cannot link computers on different sub-nets or networks. VERDICT: If you find you don't like Input Director and want to give Synergy a try, I think you'll find you really like it. PRICE: Free VERSION REVIEWED: 1.3.4 DOWNLOAD: Synergy |
Synergy Features
Synergy's function is, in essence, very simple: it allows you to control multiple PCs with the use of one keyboard and mouse. You need to install Synergy on each computer and then set one up as the "server" and the other PCs and the "clients".Synergy also lets you share the clipboard and screensaver between your computers.
Synergy doesn't take much setup and once complete, is a breeze to use–I highly recommend it.
How to Use
1. Install Synergy on every computer you want under control of your "server" and also on your server.2. Start Synergy on the client computers, select Use another computer's shared keyboard and mouse (client), type the name of your server*, and click Start.
* To get your server name, use your
server's Computer name. To get this, click the Start button, right click
Computer, and click Properties. The name is listed next to Computer
name.
3. Open Synergy on your "server" (the computer that you'll use to control the other computers connected.) Select Share this computer's keyboard and mouse (server), and click Configure…
4. Under screens, click the plus sign and add each client, by Computer name*, to the list.
* To get your computer's name, use
your client's Computer name. To get this, click the Start button, right
click Computer, and click Properties. The name is listed next to
Computer name.
5. Now you'll need to tell Synergy where each screen is. In the example below, I have three computers next to each other:GVD – SVUL – DXPL
I set the following rules (see screenshot), which states GVD is left of SVUL, SVUL is left of DXPL, DXPL is right of SVUL, and SVUL is right of GVD. I recommend leaving the percentages as is (unless you have a need to change them i.e. two screens, one on top of the other, to the left of one screen.)
6. Press OK and click Start.
You may get a pop up from your Firewall and you'll need to allow the connection. If you are using third party software, you may need to add a manual rule to allow Synergy to communicate between your computers.
Please note: It can take up to one minute to establish a connection between your computers so please be patient.
Other Settings for Synergy
I use Synergy to control my Home Theater PC (HTPC) when I'm using my laptop. One thing I noticed, after installing Synergy, was that the screen didn't power off after the HTPC was idle (a useful feature as I often walk away from my TV and leave it wasting electricity.) To fix this issue, I changed the setting on the server to not Synchronize screen savers. (As my laptop has a different screen power setting.)
You can also autostart Synergy when you start your PC (useful if you're making this a permanent setup.)
At any time, you can see which computers are connected together by right clicking the Synergy icon in the system tray and clicking Show status.
I really like Synergy; it uses minimal system resources and just works. The only problem I've found is if you Remote Desktop into from a Synergy connected PC to another Synergy connected PC and move the mouse out of the screen (confused yet), the clipboard stops working; however, this is not really a problem — more of a quirk.

Makez your Android faster
Making your Android Phone Run Faster & Smoother
Smartphones became a part of our Lives these days. Increase in the Sales
resulted in Increase in Production of Smartphones which are produced by many
companies. Also the prices of the high end phones are being replaced by small
budget phones and the production of those have reached the sky limit. But the
costly high end phone owners regret because of the slower performance and even
small budget phones are performing more than that. So there are many regretting
points for buying High end Smartphones. All these can be replaced by following
simple tricks thereby Making your Smartphone Faster and Smoother.
So, Here are some Tips which may help you to Increase Speed of your Android
Smartphone so as to Run Smoothly.
Keep Updated with Latest Software and Apps
Check for Updates which
you receive from your servers regularly. There will be minor bugs which are
being updated and which increase the Speed at times. SO, never neglect or go
revert back to older versions as there will be bugs which cause functionality
errors. Software updates tend to come
OTA (Over The Air) and you should be automatically prompted to install them,
but it doesn’t hurt to check. Go to Settings >
About device > Software update and Check for Updates and update as soon as possible.Also there will be Apps which are to be updated in Google Play Store Services. So, goto App Store, then to My Apps and Update
Apps which you use. Though the size of the App may be more, Donot hesitate to
Download as the previous Version faced some bugs and they will be fixed on
Updates.
Priority wise Give Less Priority to Land scape Wallpapers & Least to Live Wallpapers
Wallpapers do play a Key
Role in boosting up your Smartphone Device. Don’t prefer for Landscape
Images and Extremely High End Wallpapers or Screensavers which have high
resolutions and high memory intake.Also, don’t use
Live Wallpapers which can even reduce your Battery and also make your phone
slow. Live Wallpapers are just meant for special Appearance on Screen when it’s
idle. But Better not to prefer Live Wallpapers or GIF Images which affect
the increase in speed of your mobile. Its better to stick to a Static
Image which can be well performed on your Smart Device and Thus Increase the
Speed.
Clean your Home Screen
You should clean away
any unused icons and limit your widgets to the essentials. The less cluttered
your home screen is, the better in terms of performance. Don’t Mess the
Homescreen with all App Shortcuts and Widgets you are provided with.Reduce the
number of Apps and Widgets on your screen and make that free, So the Homescreen
will be flexible and Smooth.
Off or reduce animations
Make your Android Smartphone feel snappier by
reducing or Turning OFF some of
Animations. All you need to enable Developer options in
order to do this. Go to Settings > About phone and scroll down to the System section to
look for Build number. Tap on it seven times and you should see a message about being a
developer. You can now go back to the previous menu and you should see Developer options listed
under System.
Head in there and scroll down to find Window animation scale, Transition animation scale, and Animator
duration scale.
Tap each in turn and set it to .5x or off. Pick
an option and find out what suits you, if you don’t like just go back in and
change the values again.
Uninstall Unused Applications
There are lots and lots
of Apps which are to be download unnoticed and are installed without prior
information. Also there will be apps which are to be downloaded for time being
but of Large Size and occupies Cache Memory and RAM. Also RAM Utilization will
be more if you install many Apps. So, you need to have more RAM or to Increase
RAM
Delete as many Unused
And Unwanted Apps. This is very important by which you can Make ease interface
with your Smartphone. Select the App which you won’t use and remove by clicking
on Uninstall Button. Mak sure that the data is safe and is not Deleted. You can
even uninstall multiple Apps by using Easy Uninstaller App where you can just
select the Apps and Throw them away from your Smartphone.
Clear Cached App data
Cached data for apps
help to load more quickly and increase the functionality of the App. It makes
the App go faster. But it can build up over time to take up quite a lot of
space. Also there will potentially be cached data in there for apps that
you no longer use. Sometimes clearing cached data for an app can also help
clear up flaky behavior.
If you want to
pick individual apps then head into Settings
> Apps and slide over the All tab and tap on the
relevant app then choose Clear cache. If you’ve decided
to just clear the whole lot then go to Settings
> Storage and tap on Cached
data and then tap OK.
Prefer Third Party Launchers
Some of the customizations that OEMs make to their
devices can be heavy-handed. Vexed up with using the same old default launcher?
If you want to change the feel of navigating around, and tweak some settings to
make it feel speedier, then you might find that a third-party launcher does the
trick. Try out something like Nova Launcher, Buzz
Launcher, or Apex Launcher. Experiment with the settings and you should find
that your device feels a lot faster.
Disable Background Data (Reduce Auto Sync)
The
Emails like Gmail, Facebook, Twitter, backup app etc etc will always
want to ping the Internet for data on a regular basis. All that syncing not
only bites up your battery power, but also take up system resources and
slows down your device.
There are some services
you may want to sync in real time, but there are others you can check manually.
For example, if you don’t need to be alerted the moment you get a Facebook
notification or receive an email to your personal account, you can prevent
those from connecting in the background. Stop Auto Syncing and do a
manual sync when you seriously need it.
You could go to Settings and find Auto-sync under Accounts and
just turn it off altogether, but that will be too drastic for most people.
Instead why not just reduce the sync frequency and remove any accounts you
don’t really need? For a lot of apps, like Facebook, you’ll need to open up the
app and find the settings to reduce the sync frequency.
Factory Reset your Smartphone
There will be a junk
files ready to be accumulated in your phone which is so called as a dump file.
This is just because the data which is stored in memory. So, its better to
perform a factory Reset when you feel like its slowing down or getting
struck frequently while playing high end games or running background
applications.
Go for Custom Rooting, ROMizing
Risk takers and advanced users can also root their device , which will open the door to new features and
even greater performance boosts. Rooting gives you the ability to overclock the
device’s processor, install a custom ROM, and other things; however it also
voids your warranty and could cause irreversible damage to the device.
So, Follow the above 10
Tips to Increase the Speed of your Android. By following the above tips, your
Android Device runs Faster and Smoother. If you have any doubts or Issues with
your Android device, DO comment below. Any Tips and Tricks unmentioned are
accepted.
