MS-DOS

The command for deleting a file in DOS is DEL. If the file you are trying to delete is in the current directory, type DEL followed by the full filename. E.g. del file001.txt If there are multiple files, the wildcard * can be used. del file*.txt will delete all the text files that start with 'file' del file*.* will delete all the files that start with file. del *.txt will delete all the text files. del *.* will delete all the files in the current directory. It is possible to delete files in another directory by typing the full path and filename del c:\folder01\*.* will delete all the files in the directory c:\folder01\ DEL will not affect hidden files, but careless use of this command could damage your operating system so use with care.

1) When in DOS at the C:/, type RD (remove directory)
2) hit Enter key

C:/
C:/RD
Enter

To use the archive attribute (A), back up files telling the archiving application (WinZip, etc.) to clear the archive attribute of the files it stores copies of. Whenever one of those files is modified in the future, or whenever a new file is created, its archive attribute is set. Therefore, on subsequent backups, you can have the application back up only files that have the archive attribute set (and clear the archive attribute while doing so). That way you don't waste time and drive space backing up files that haven't changed since the last time they were backed up.

If your laptop will stay on in DOS mode then update your BIOS

MS-DOS comes with every Microsoft computer, just go to start>all programs>accessories>command prompt.

You should get a book on DOS before you start entering commands.

Have Fun.

MS=Microsoft DOS = Disk Operating System. The Microsoft precursor to Windows It was loaded on to a PC via floppy disks

MS-DOS was created by Microsoft, who bought the rights to 86-DOS from Seattle Computer Products in 1981 and modified it to IBM's specifications who then released it as PC-DOS 1.0. It was also released as MS-DOS to run on PCs. MS-DOS went through eight revisions and was finally discontinued in 2000.

Answer: In dos you have to create the complete application, yourself in other words the complete .EXE file, that can be done in any of the many different programming languishes IE. GWBasic, QBasic, C, or ASM etc., the last is the most difficult but the result is the fastest application. Where Windows is a platform for your application, most of the things you want to do is already created in Windows, all you have to do, is to use it from within your application, not that it means less programming, you actually have to do more coding than with Dos, for instance in Dos GWBasic, if you want to read data from a comm. port you just open it as follow

[code]

open "comm1:" for input as #1

input #1, var

close #1

[/code]

But in Windows it is a long story

If you are getting that error, it means that either Java is not installed, or is not in your path.

If Java is not installed, go to http://www.java.com to install the most recent version of the JRE.

If you're sure you have already installed Java ensure the Java executable is in your system's path. You can do this by first finding the directory it is installed in. For example, mine is installed in C:\Program Files\Java\jre6. The executables are located in the bin directory.

In order to set your path (Assuming Windows Vista), go to Start -> Control Panel -> System, then click on the 'Advanced System Settings' link on the left, then the 'Environment Variables' button. In the lower section (Labeled 'System Variables'), scroll through and find the item labeled 'Path' and double click it. In the field labeled 'Variable value' go to the end and add a semicolon (;), and then the path your installation of Java is located. Using the example I gave above, I would have added ;C:\Program Files\Java\jre6\bin to the end of the line.

The procedure for 64-bit Windows Vista or Windows 7 is the same, except the text you will add to the Path variable is ";C:\Program Files (x86)\Java\jre6\bin". Notice there is still a semi-colon at the beginning of the line.

Once you have done this, you will need to close and reopen the command prompt if it is already open, and you should be able to run java without getting this error message.

Why didn't Windows NT replace DOS. as originally planned?

If you just want to display the hidden files, run following command:

dir /ah

this will show you all hidden files and folders..

However if you want to change the attributes permanently, use attrib command..

Yes only one program at a time as it is a single user OS..

There are several factor that decide this, the two most important are the size of the files and the size of the directory/drive. With out this no estimate can be made

The autoexec.bat and the config.sys were files created for MS-DOS and Windows 3.x as an easy solution of loading the files required for various devices as well as the operating system to properly run. These files are required for later revisions of MS-DOS and Windows 3.x to load. Because Microsoft is trying to steer away from MS-DOS, these files are not required for Windows 95, Windows 98, Windows NT, Windows ME, Windows 2000, Windows XP, or later operating systems. However, in some cases it may still be necessary for users to edit or configure these files.

DOSBox is an x86 emulator that allows users to run older DOS-based applications and games on modern operating systems. It creates a virtual environment that emulates the hardware and software of a DOS system, enabling compatibility with programs that require MS-DOS. Users can mount directories as drives, providing access to files and applications within the emulated DOS environment. DOSBox also includes various features like customizable settings for graphics, sound, and input to enhance the user experience.

You can use any text editor but notepad++ which is free is the best. When you save the file be sure to set it to all file types and save it with a .bat extension!

Install Firefox and run the following command:

"cd c:\program files\mozilla firefox" and press enter.. It will give you the prompt -

C:\Program Files\Mozilla Firefox> now just execute here "firefox.exe" ..

The label command lets you set or change the 11-character label of a drive. The vol command only displays it, along with its serial number.
