Windows 命令复制文件而不提示输入 bat 文件

Question

I would like to make a.bat file which will make a backup for my kdbx file. I have two simple commands there.

cd C://Access
xcopy access4.kdbx access4.backup.kdbx /Y

but the second one ask me: Does access4.backup.kdbx specify a file name or directory name on the target (F = file, D = directory)?

I dont understand why Windows does not recognize the file in the source. Also I don't see any option to set it up in the command. How can I solve it?

Answer 1

You are mixing simple and multiple copying of files:

xcopy is to be used for copying multiple files.

copy is to be used for copying just one file.

So, your command should be:

copy /Y access4.kdbx access4.backup.kdbx

Answer 2

To begin with, the Windows path separator is \ but not / or // .

Then you should use cd /D rather than plain cd since you specified also a drive letter.

The quick solution is to use copy rather than xcopy , because it does not show such a prompt:

cd /D "C:\Access"
copy /Y "access4.kdbx" "access4.backup.kdbx"

However, xcopy features a lot of additional options in contrast to copy , so the latter might not help in certain situations.

To avoid the prompt, you could pre-create the destination file and let xcopy overwrite it:

cd /D "C:\Access"
>> "access4.backup.kdbx" rem/
xcopy /Y "access4.kdbx" "access4.backup.kdbx"
