How can such a batch program be written in BAT?

Are you copying the entire file or a specific file?

1. Specific Documents.

Format: Copy Source File [Target File].

Instructions:1The source file specifies that the file you want to copy comes from ** - [drive letter 1:] [path 1] [file name 1].

2.The target file specifies where the file is copied - [drive letter 2:] [path 2] [file name 2].

3.If the default drive letter is the current drive letter; If the path is the current directory, it can be the default path.

4.The source file name cannot be defaulted, and the target file name is the default name, which means that the file name will not be changed after copying.

Examples:1Copy the A drive to the DOS directory of the C drive, and the file name remains unchanged.

Type copy a: dos; Omit the target drive letter and file name.

1 file(s) copied ;The screen displays the feedback message: A file has been copied.

2.Copy the files in the C: DOS directory to the Be directory of Drive A, and the files will be renamed.

c:\>copy \dos\ a:\

3.Add all of the C:DOS directory. Copy the sys file to the rs directory of disk A.

c:\dos>copy *.sys a:\rs

2. Copy the whole disk or folder.

Format: [drive letter] [path] xcopy [source] [target] [s][e].

Instructions:1Drive letter and path.

2.This command not only copies files, but also subdirectories.

3.Parameter s: Copies all files and files in their subdirectories. If there is no s in it, the subdirectories are not copied.

4.Parameter e: Must be used with s to copy all files and files in their subdirectories. Empty directories are also copied, and if this parameter is not included, empty directories will not be copied.

Examples:1Copy all files in the SE directory of drive A to the SE directory of drive C.

a:\xcopy \se\*.c:\se

If the C drive does not have the directory SE, it will ask whether the SE is the file name or the directory name.

Type f to indicate that SE is the file name. If you type d, SE is the directory name, and the xcopy command will automatically create the directory and complete the copy.

2.Copy all files in the BE directory of drive A, their subdirectories (not empty directories) and files to the BE directory of drive C.

a:\>xcopy \be\*.c:\be /s

3.Copy all files in the BE directory of drive A, their subdirectories (including empty directories) and files to the BE directory of drive C.

a:\>xcopy \be\*.c:\be /s/e
