If you are trying to back up memory and files on computer then the best thing to do is buy a flash drive. Flash drives are not expensive and can be found at almost any retail store that sells electronic. I would recommend that you get a flash drive with at least one gig of memory or more. This type of flash drive should only cost you twenty bucks or so.

I would recommend that you get specific size of flash drive for different types of memory. If you are planning on backing up videos, then you need to get a removable hard drive in place of a flash drive. If you are using a removable hard drive then the directions are the same as using a flash drive. Just complete the same step in the same order just like a flash drive. If you are planning to store many images then either a high-end flash drive or a lower end hard drive is recommended. If you are planning to store office documents and other written materials, then a low to medium priced flash drive will work fine.

Videos need 100 gigs or more. Pictures need between 3 and 15 gigs. Word documents and other office documents should not take more than one gig. I would also be concerned with the transfer speed if you are planning to store videos.

To start you need to insert the flash drive into your computer through the USB port in either the side, back, or front of your computer. The USB port you plug the flash drive into does not matter unless you know that a specific USB port does not work.

After the flash drive is in the computer, go to “my computer” in windows and double click on shared documents folder. Browse though the folders and find the specific file, files, folder, or folders you want to back up with the flash drive. Select “send to”, and then highlight the removable disk or removable memory. Once you select this, the files should start to transfer to the removable disk.

After the memory you are backing up is completed with the transfer, do not just take the flash drive out of the USB. You need to right click on the icon that says “removable device” and select the eject button. This will allow windows to safely eject the flash drive without causing any harm to the computer or the flash drive.

After you have hit eject and safely removed the flash drive or hard drive, you will have a memory back up that is good as long as you store it room temperature and do not submerge  it in water. It is always a very good idea to back up and data that is important on your computer. One last thing you want to remember is that generic brands will work just fine on everything but video memory backup. This will save you money too.

I've decided to use Ubuntu as the Operating System which will interact with my files. Using Ubuntu will allow me to format my hard drive in ext3 which will automatically lock out any windows users from viewing my files. The second advantage of using Ubuntu is the live cd. A live cd does not save anything to the hard drive of the shared computer. You can browse the internet or view you files without saving any history, once you shut down the computer there is no trace of your being there. Also if you use passwords, a key logger installed onto the shared computer will not be able to log your keystrokes (unless there is a hardware key logger).

Storage

I've decided to use a portable hard drive as it adds a level of security to your files, with the ability to physically move it. A portable hard drive allows you to connect to you files from multiple computers.

Ubuntu and Portable Drives

If your shared computer can boot from usb you can install Ubuntu onto the portable hard drive. This gives you the advantage of having a whole OS to yourself which others cannot access. All your files and history will be saved to you hard drive not the shared computer. This also allows you to move between shared computers and keep all your settings.

Social Engineering

The best way to protect your private files is to convince people they don't exist. For example if users know you have private files on you hard drive they will be curious to access them. First we want to place some fake files like our shared files on the drive. Second if other users do get curious and get access to your drive we want to protect the files on the drive using encryption.

Windows

If you have an older shared computer you might be stuck with windows. If you cant boot the computer from cd or usb there are some great tools you can still use. Portableapps.com allows you to use tools such as email, web and video. Unfortunately the files you open will appear in recent documents and your key strokes could be recorded.

If your bios booting options have been blocked it is likely that your web browsing is being monitored. If this is the case you will want to use a proxy to cover your internet tracks.

• Archive format:7z
• Compression level: Ultra
• Compression Method:LZMA
• Dictionary size: 64MB
• Word Size:64.

Once done you can delete those files you were trying to hide because they are now in the .7z file you just made. Open command prompt by going to start run and put in cmd. to make it easier make a folder on your desktop and put the .7z file and the .jpg file in the folder so its all in one place.

Lets call the folder its in x123 the .7z file shadow.7z and the .jpg return.jpg. So now in command prompt it should say c:/ documents and settings> "your pc's name">. Now next to that put cd x123 so it opens the folder it should now be c:/ documents and settings>"Your pc's name">x123>. After that put in COPY /B return.jpg + shadow.7z returnsecret.jpg after this it should say 1 file copied and there should be a new .jpg file in your x123 folder called returnsecret.jpg.

To get the files off of the new image file lets say you had passwords there and you need to get them back open 7-zip again and select returnsecret.jpg now press the extract button. There should now be a folder called returnsecret with the files you just hide inside the image. You can delete this folder and extract it again from the image over and over. Hide it in a thumbdrive,psp,external drive, iPod, or any mass media and only you will know that the files are there or even how to extract them.

Free space is needed for the obvious reason that when you want to save a file, it needs somewhere to write that file. Free space is like have extra paper in a notebook when you are taking notes in class. You may be able to find a blank space on some other sheet that has already been used, but it will not be as efficient as a new sheet. It will be harder to find when you need it and harder to add more information to.

Having free space on the hard drive allows your computer to find room for your files easily and efficiently. For small files like you create in a word processor, this is not too much of a problem. But, when you want to install new software, a lack of free space can be a serious detriment. Most software checks your free space first. If your drive is short on space, it will refuse to install its files or will only allow enough for limited function of the software.

The second use of free space is a little more complicated than just having some extra paper in a notebook. Your computer needs extra room to think sometimes. In the same way that you may write down some random thoughts for future reference so you will not forget, the computer does roughly the same thing.

If you have plenty of ram in the computer and are only running one or two applications that are not memory hogs, your computer will just hold everything in its electronic memory. This is like people remembering a short grocery list of 4 or 5 items. When this list gets to be 10 or 20 items, people usually write it down.

If you are running several programs at once, this can exceed your computer's ability to hold everything in its random access memory. Every window that you have open is a new program for the computer. Games and graphics programs tend to take more memory.

Once the memory is exceeded, your computer will write out everything about one or more programs in a special area of the hard drive so it can be retrieved when you or a program needs it later. This can hog up many many megabytes of memory at one time. If it can lay a lot of memory onto the hard drive, lots of ram will be liberated for operating purposes.

When you are swapping from window to window, if you notice your computer is hitting the hard drive a lot, it is having trouble keeping enough room on the hard drive and in memory to run efficiently. Sometimes defragmenting

It goes to the index, which is really like the index in a reference book, to find the information that you or a program has requested. Once it finds the location in the index, it goes out to the area where the rest of the files are stored, finds the right file, and loads it into memory for use.

When information is erased from your computer, most of the time all that happens is that it is removed from the index. This makes the computer think it is gone. It may be weeks, months, or never before it is actually erased or overwritten. This is why computer geeks can often recover lost or deleted files from a hard drive. They simply scan the entire surface of the drive until they find any of the data that remains.

Unless you use a program that actually overwrites the file, it will remain for a while. Some data is left until the disk is either formatted or defragmented. Some of these files just sit there taking up space because they tell your computer not to delete them.

When you write files on a hard drive, they are allocated a little extra room beyond what they originally need. This way if you write to them again, the file can stay together. However, if you have added more files in the meantime, it may not have left enough surplus space. Your file is then broken into pieces and written in other blank areas of the drive.

This problem also happens when there is a space left from a deleted file. If the computer figures out that it is large enough to hold your new file, it will write it in that limited area. However, if you have deleted a lot of small files over time, your disk will have lots of little spaces that nothing else can fit into.

Now, you have two situations going. Files that are fragmented here and there on the disk, and little spaces on your drive that cannot be reused. This causes your computer to slow down because it has to read two, three, or more times to get one file. It also has to look at each of those small spaces each time it writes to check for reusable room. This makes your computer run slower because it is having to do a lot of additional work.

When you defragment a hard drive, it gathers up all of the pieces of each file and rewrites it in one piece somewhere else on the drive. As file after file is rewritten, the spaces that the file used to occupy are left blank. Eventually, all of those openings cause those little spaces to get linked together into larger and larger amounts of usable free space.

Ideally, when a defragmentation is complete, all of the files are in one piece, and all of the free space is one large block ready to be subdivided again. Your computer will usually recommend not to defragment a drive that is less than 5% to 10% fragmented. If you are defragmenting thinking it will erase all of your old data that you do not want recovered, this is probably not going to happen. Some will be written over, but not nearly as much as you think unless your hard drive is over 90% full.

I'm sure most of us in some way shape or form have unwanted material stored onto our computers automatically after being viewed on the internet, which are still, viewable by anyone. But don't take this article as ONLY an effective way to remove these files, it's also an effective way of freeing up space on your hard disk altogether, improving the overall performance of your computer!

Here are simple instructions for viewing and or deleting these files.

1. Click Start button
2. Click Control Panel
3. Click on “Performance and Maintenance”
4. Under “Pick a task” you should see a link that says “Free up space on your hard disk”. Click this.

A “Disk Cleanup” window should pop up, and begin calculating your stored files.

(This process will likely take a few minutes)

When the calculation process is complete, and new window should pop up, named something along the lines of “Disk Cleanup for [your computer name here] (C:)”.

If you search across it, you will come across the words “Files to delete:”.

Click highlight the “Temporary Internet Files” selection, go down to the lower part of the window, and click the “View Files” button.

A new window named “Content” should come up, with files with random lettering on them; you may open these files, and few everything you've come across on the internet so far.

Once you are ready to delete these files, go back to the “Disk Cleanup” window, make sure there's a check mark in the box next to “Temporary Internet Files”, and click the “OK” button at the bottom of the window.

A box should come up asking if you are sure you want to perform these actions. Click Yes.

And there you have it! Your first method of removing unwanted files from your computer!

A second, alternative method is downloading, and using “Media Detective”. They offer a free 1 month trial, so you could just use it and lose it if you wish.

Good luck to you and your new clean computers!

1. Open a Command Prompt window and leave it open.
2. Close all open programs.
3. Click Start, Run and enter TASKMGR.EXE
4. Go to the Processes tab and End Process on Explorer.exe.
5. Leave Task Manager open.
6. Go back to the Command Prompt window and change to the directory the AVI (or other undeleteable file) is located in.
7. At the command prompt type DEL where is the file you wish to delete.
8. Go back to Task Manager, click File, New Task and enter EXPLORER.EXE to restart the GUI shell.
9. Close Task Manager.

Or you can try this.

1. Open Notepad.exe
2. Click File>Save As..>
3. locate the folder where your undeleteable file is
4. Choose "All files" from the file type box
5. click once on the file u wanna delete so its name appears in the "filename" box
6. put a " at the start and end of the filename
7. (the filename should have the extension of the undeleteable file so it will overwrite it)
8. click save,
9. It should ask u to overwrite the existing file, choose yes and u can delete it as normal

Here's a manual way of doing it.

1. Start
2. Run
3. Type: command
4. To move into a directory type: cd c:*** (The stars stand for your folder)
5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:progra~1kazaal~1
6. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.
Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.

• Include the windows.h library.
• Use the following function:

Here is the complete code to open “WordDocument.doc”:

Ok, so you know how to open files, but what if you want to open a folder?

You would do this:

Now, let's open a website:

Yay! Now you know how to open files, folders, and websites through C++ programs!
