Self made Folder Lock Software for your PC

Ever thought if you could have some of your personal files hidden in your pc without having to use a Complicated software or having to pay for that extra thing ? ? ?
Now it is more than easy ,even for a basic program learning kid  or a noob to create it easily,  creating one at your house.All you need is a notepad file ,basic programming knowledge thats it ! ! ! ! ! ! Nothing Extra .

1. Create a folder of any name you  prefer.
2.  Within this folder create a text file or a notepad and copy the following code in the text file

Quote: cls
@ECHO OFF
title Folder Private
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Private "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to unlock folder
set/p "pass=>"
if NOT %pass%== Folder Lock here goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully

MKV [Demuxing , Encoding and Muxing]

Matroska(MKV) is getting popular by the day and with most HD Content being distributed in the MKV Container.

Tools Required :
1. MKVToolNix  - http://www.bunkus.org/videotools/mkvtoolnix/downloads.html
2. H.264 Info - http://sourceforge.net/project/showf...kage_id=225029
3. MeGUI - http://sourceforge.net/projects/megui


Part 1 : Demuxing an MKV into elementary streams

1. Start MKVMergeGUI from the MKVToolNix Installation Folder

2. Drag and Drop your MKV Video file to the “Input Files” container .

3. Notice the Streams you want to extract .

4. Now open a Command Prompt from
Start->Program Files->accessories->Command Prompt

5. Change to the directory where you have MKVToolNix installed

6. Now to demux the file you’ll use a program called mkvextract .

7. On the command prompt , type this code:

mkvextract tracks <Full MKV Path> 1:<Full path where you want to store your Extracted Video> 2:<Full path where you want to store your Extracted Audio>

Note: The most simple way to enter path of a file in CMD is to just drag and drop it into the Prompt and it’s path will automatically be added .

8. This will extract the Video and Audio streams separately in the locations C:\Video.264 c:\Audio.aac

Part 2: Encoding the Video and Audio

1. Open up H264Info

2. Load the file using the input button and then change the Profile Level of the file to 4.1 , this will make sure that the H.264 Video plays well on most HD Players and the Xbox 360 as well .

3. Save the output as video-4.1.264

4. Now if you want to encode the audio then encode it to whatever format you like using any encoder like dBPoweramp or whichever encoder you like . we’ll leave the audio encoding part here as AAC works fine .

Part 3: Muxing into an MPEG-4 File

1. Now , to combine these streams into s single MP4 file we’ll have to Multiplex it.

2. Fire up MeGUI

3. Go to Tools->MP4 Muxer

4. Now set the Video Input , the Frame Rate , the Audio Input and Finally select the Output Destination .

5. The resultant file is a fully standards compliant mp4 file and will play in any player that supports H.264 and AAC .

Physical Memory Addressing Issues on Windows 7 32 bit OS

Increasing workstation performance and RAM affordability have enabled more and more users to push the limits of 32-bit computing.Microsoft Windows XP Professional, designed as a 32-bit OS, supports an address range of up to 4 GB for virtual memory addresses and up to 4 GB for physical memory addresses. Because the physical memory addresses are sub-divided to manage both the computer’s PCI memory address range (also known as MMIO) and RAM, the amount of available RAM is always less than 4 GB.
                        The PCI memory addresses starting down from 4 GB are used for things like the BIOS, IO cards, networking, PCI hubs, bus bridges, PCI-Express, and video/graphics cards. The BIOS takes up about 512 KB starting from the very top address. Then each of the other items mentioned are allocated address ranges below the BIOS range. The largest block of addresses is allocated for today’s high performance graphics cards which need addresses for at least the amount of memory on the graphics card. The net result is that a high performance x86-based computer may allocate 512 MB to more than 1 GB for the PCI memory address range before any RAM (physical user memory) addresses are allocated.
                                          From a user’s perspective the graphics card selected and amount of installed RAM have the most impact on available RAM. A high end graphics card with 256 MB of memory may limit addressable RAM to about 3 GB while cards with less memory may enable higher limits. Industry memory architectures impact the opportunity to install just the amount of RAM that can be made available. Today’s high performance chipsets use dual memory channels which require matched pairs of DIMMs for the best performance. On a 4 DIMM slot computer, the 3 to 4 GB capacity choices fall to 3 GB or 4 GB (two 1 GB DIMMs + two 512 MB DIMMs or four 1 GB DIMMs).

P.S.- The same applies for Windows 7 as well
