Copying all files from one folder to an other with command line in windows

I have two folders src and dest:

src
  --new.txt
  --style.css

dest
  --text.txt
  --install.bat

I would like to copy all files inside src into dest. I have tried copy src dest but that destroys everything that is inside dest.

Is they a way to copy all files/folders inside src into dest ?

how the dest folder should be after the copy:

dest
  --text.txt
  --new.txt
  --style.css
  --install.bat

xcopy /s src\*.* dest doesn't work for you?

If you specify only the folder, it replaces the entire folder for you. When you specify the items inside the folder (with *.*), it copies the actual files instead of the folder.

Example below:

C:\Users\User>xcopy /s test\*.* test2
test\1.txt
test\2.txt
2 File(s) copied

C:\Users\User>dir test2
 Volume in drive C has no label.
 Volume Serial Number is 3018-ED8A

 Directory of C:\Users\User\test2

06/02/2014  09:38 AM    <DIR>          .
06/02/2014  09:38 AM    <DIR>          ..
06/02/2014  09:37 AM                 5 1.txt
06/02/2014  09:37 AM                 5 2.txt
06/02/2014  09:37 AM                 5 3.txt

I think You should use xcopy command. It copies all file structure within the directory:

xcopy src dest /s /e

This two parameters instruct it to copy all files directories within src including empty ones

I finally used

robocopy src\ dest /E

which is able to copy even files with long paths.

copy scr dest

should be enough altough it will not copy subdirectories

if you have same file in the destination folder you should have a message like this one:

C:\>copy tmp tmp2
tmp\bifish.txt
tmp\mal.log
Overwrite tmp2\mal.log? (Yes/No/All): no
tmp\png_create_201401.sql
tmp\png_data_201401.sql
        3 file(s) copied.
