Create nameless files and folders in windows

This trick will allow you to create files and folders without any name.

Just follow the following steps:

1.Select any file or folder.
2.Right click on it, press rename or simply press F2.
3.Press and hold the alt key. While holding the Alt key, type numbers 0160 from the numpad.

Note: Type the numbers 0160 from the numpad, that is, the numbers present on the right side of the keyboard. Don't type the numbers which are present on top of the character keys.

4.Press Enter and the nameless file or folder will be created.

Reason: The file or folder that seems nameless is actually named with a single space.

But what if you want to create another nameless file or folder in the same directory ?

For this you will have to rename the file with 2 spaces. Just follow these steps below:

1.Select file, press F2.
2.Hold alt key and type 0160 from the numpad.
3.Release the alt key. Now without doing anything else, again hold alt key and press 0160.
4.Press enter and you will have second nameless file in the same directory.
5.Repeat step 3 to create as many nameless files or folders in the same directory.

Make Undeletable Or Unreadable Folders

By holding down alt, then typing numbers on the number pad (right of the keyboard) you can create special characters.

If you hold down alt, then press 1, then let go, you got the ascii character 1. You try some randomn numbers. This goes all the way up to 255.

Open a dos prompt, and type md (alt+1+9+4)someword.

md is the dos command to make a directoy,

now try and open the directory in Windows, you can't.

To open it, type ren (alt+1+9+4)someword someword (ren is the dos command to rename).

Rename Multiple Files at Once

When you download photos from your digital camera, they often have unrecognizable names. You can rename several similar files at once with the following procedure. This also works for renaming other types of files.

1.Open the My Pictures folder. (Click Start, and then click My Pictures.) Or open another folder containing files that you want to rename.

2.Select the files you want to rename. If the files you want are not adjacent in the file list, press and hold CTRL, and then click each item to select it.

3.On the File menu, click Rename.

4.Type the new name, and then press ENTER.

All of the files in the series will be named in sequence using the new name you type. For example,

if you type Birthday, the first will be named Birthday and subsequent files in the series will be named Birthday (1), Birthday (2), and so on. To specify the starting number for the series, type the starting number in parentheses after the new file name. The files in the series will be numbered in sequence starting with the number you type. For example, if you type Birthday (10), the other files will be named Birthday (11), Birthday (12), and so on.

Syntax Notes

To be functional, each DOS command must be entered in a particular way: this command entry structure is known as the command's "syntax." The syntax "notation" is a way to reproduce the command syntax in print.

For example, you can determine the items that are optional, by looking for information that is printed inside square brackets. The notation [d:], for example, indicates an optional drive designation. The command syntax, on the other hand, is how YOU enter the command to make it work.

Command Syntax Elements

1. Command Name

The DOS command name is the name you enter to start the DOS program (a few of the DOS commands can be entered using shortcut names). The DOS command name is always entered first. In this book, the command is usually printed in uppercase letters, but you can enter command names as either lowercase or uppercase or a mix of both.

2. Space

Always leave a space after the command name.

3. Drive Designation

The drive designation (abbreviated in this book as "d:") is an option for many DOS commands. However, some commands are not related to disk drives and therefore do not require a drive designation. Whenever you enter a DOS command that deals with disk drives and you are already working in the drive in question, you do not have to enter the drive designator. For example, if you are working in drive A (when the DOS prompt A> is showing at the left side of the screen) and you want to use the DIR command to display a directory listing of that same drive, you do not have to enter the drive designation. If you do not enter a drive designation, DOS always assumes you are referring to the drive you are currently working in (sometimes called the "default" drive).

4. A Colon

When referring to a drive in a DOS command, you must always follow the drive designator with a colon (:) (this is how DOS recognizes it as a drive designation).

5. Pathname

A pathname (path) refers to the path you want DOS to follow in order to act on the DOS command. As described in Chapter 3, it indicates the path from the current directory or subdirectory to the files that are to be acted upon.

6. Filename

A filename is the name of a file stored on disk. As described in Chapter 1, a filename can be of eight or fewer letters or other legal characters.

7. Filename Extension

A filename extension can follow the filename to further identify it. The extension follows a period and can be of three or fewer characters. A filename extension is not required.

8. Switches

Characters shown in a command syntax that are represented by a letter or number and preceded by a forward slash (for example, "/P") are command options (sometimes known as "switches"). Use of these options activate special operations as part of a DOS command's functions.

9. Brackets

Items enclosed in square brackets are optional; in other words, the command will work in its basic form without entering the information contained inside the brackets.

10. Ellipses

Ellipses (...) indicate that an item in a command syntax can be repeated as many times as needed.

11. Vertical Bar

When items are separated by a vertical bar (|), it means that you enter one of the separated items. For example: ON | OFF means that you can enter either ON or OFF, but not both
