Batch move file with using regex to new folder

There can be used something like this:

md "new folder"
move "*@2x*" "new folder"

In batch files, *a means everything that ends with a; b* means everything that starts with b; a*b means everything that starts with a and ends with b; a?b means everything that starts with a, has one character between a and b and ends with b. So * is a wildcard for everything and ? is a wildcard for every character.

See: MS-DOS and Windows Wildcard Characters on Microsoft's documentation site.

You can try something like that :

 @echo off
 MD "new folder">nul 2>&1
 setlocal enabledelayedexpansion
 for /f %%f in ('dir /b *@2*') do (
     move "%%~f" "new folder"
 )
 Echo done
 pause

There can be used also:

%SystemRoot%\System32\robocopy.exe . "new folder" *@2x.* /MOV /NDL /NFL /NJH /NJS >nul

The entire directory tree to the specified destination folder – in this case the subdirectory new folder in current directory – is automatically created by ROBOCOPY on not existing before moving all files in current directory matched by the wildcard pattern *@2x.*.

Run in a command prompt window robocopy /? for help on this command.

Normally your regex syntax seem to be correct. But when you check "findstr" documentation the plus (+) character is not in accepted list :)

Findstr doc: https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/findstr

You can try this:

@echo off
setlocal enabledelayedexpansion
MD "new folder">nul 2>&1
for /f %%f in ('dir /b ^ | findstr /r "(^.*@2.*$)"') do (
    move "%%~f" "new folder"
)
Echo done
pause
