This article is about how to use Xcopy to copy and back up a large number of files. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

First of all, what is Xcopy?

Xcopy is a Windows built-in tool to copy files and directories, can copy subdirectories, is a very easy to use command line tool.

The common way to copy a tape subdirectory is:

Xcopy "d:\ website"d:\ webbak" / s/e/y

For website backup, we can copy only those files that have been modified, using the following command:

Xcopy "d:\ website"d:\ webbak" / s/e/y/d

This command automatically copies files with changed dates based on the date of the file.

Finally, use more formats:

XCOPY source [destination] [/ A | / M] [/ D [: date]] [/ P]

[/ C] [/ I] [/ Q] [/ F] [/ L] [/

[/ K] [/ N] [/ O] [/ X] [/ Y] [/

[/ EXCLUDE:file1 [+ file2] [+ fi

Source specifies the file to copy.

Destination specifies the location and / or name of the new file.

/ An only copies files with archived property sets

But does not change the attribute.

/ M copies only files with archived property sets

And close the archive properties.

/ D:m-d-y copies files that are changed on or after the specified date.

If no date is provided, only those source times are copied

A file newer than the target time.

/ EXCLUDE:file1 [+ file2] [+ file3]...

Specifies a list of files that contain strings. Every string

Must be on a separate line of the file. If there is any

The absolute path between the string and the file to be copied

Match, that file will not be copied.

For example, a string that specifies a string such as\ obj\ or .obj will line

All files under the directory obj or with

The file with the .obj extension.

/ P prompt before creating each target file.

/ S copies directories and subdirectories except for empty ones.

/ E copy directories and subdirectories, including empty ones.

Same as / S / E. Can be used to modify / T.

/ V validate each new file.

/ W prompts you to press the key before copying.

/ C continues to copy even if there is an error.

/ I if the target does not exist, more than one file is being copied

Assume that the target must be a directory.

The file name is not displayed when / Q is copied.

/ F displays the full source and destination file names when replicating.

/ L displays the files to be copied.

/ G allows unencrypted files to be copied to

Encrypted targets are not supported.

/ H also copies hidden and system files.

/ R overwrites read-only files.

/ T creates a directory structure, but does not copy files.

Empty directories or subdirectories are not included. / T / E includes

Empty directories and subdirectories.

/ U copies only files that already exist in the target.

/ K copy attributes. A normal Xcopy resets the read-only property.

/ N is copied with the generated short name.

/ O copy file ownership and ACL information.

/ X copy file audit settings (implied / O).

/ Y copies file audit settings (implied / O).

Existing target file.

/-Y causes a prompt to confirm that a

Existing target file.

/ Z copies network files in restart mode.

The command line switch / Y can be set in advance in the COPYCMD environment variable. This may be overwritten by /-Y on the command line.
