1. Create directory :
    mkdir DirectoryName
    mkdir MrSadin
2. Navigate to directory :
    cd DirectoryName (Or Path)
    cd MrSadin
3. Delete Empty Directory : (Attention, directory should be empty)
    rmdir DirectoryName
    rmdir MrSadin
4. Delete directory that contains some files
    rmdir /s DirectoryName
5. Create empty file :
    echo. > fileName.extension
    echo. > TestFile.txt
6. Create file with content :
    echo. Your-Content > fileName.extension
    echo. This is my file > Test.txt
7. Delete file :
    del fileName
    del TestFile.txt
    del Test.txt

8. Copy a single file:
    copy C:\Users\desktop\Example.txt D:\backup\Example.txt
9. Copy all of the files in a folder:
    copy C:\Users\desktop\*.* D:\backup
10. Copy files when the file or folder has a space in the name:
    copy "C:\Users\My Documents\*.*" "D:\2015 Backup"
11. Combine (concatenate) text files
    copy file1.txt+file2.txt newFile.txt
12. Copy a folder to another location
    xcopy C:\tools\* D:\backup\tools /e /i
/e tells xcopy to copy all of the subdirectories in the source location as well. This includes any empty directories.
/i tells xcopy to assume that the destination is a folder. This will force it to create the new folder during the copy process.
It is most useful when copying files from a CD or DVD. It will remove the Read-Only attribute automatically during the copy process.

13. Use xcopy to copy hidden files
    xcopy C:\tools\* D:\backup\tools /e /i /h

14. Use robocopy to easily copy folders. The robocopy command replaces the xcopy command. It can quickly copy entire folders without having to worry about defining the contents. For example, to copy all of the contents of the C:\tools directory to the new folder D:\backup\tools, enter the following:
    robocopy C:\tools D:\backup\tools /e

16. Mirror a directory. Mirroring a directory is great for making backups. The mirror option of robocopy will copy all of the contents from the source to the destination. It will then delete anything at the destination that doesn't exist at the source. This ensures that your backup only has the latest versions of your files. For example, to mirror C:\Users\My Documents to D:\backup\My Documents, enter the following
robocopy "C:\Users\My Documents" "D:\backup\My Documents" /mir
