Delete files that don't have special character ® in name or path

Question

I have seen How to delete all files that don't have a certain string in their name

However, I would like to delete files that do not have a certain string in their filename or path (not only filename), and I would like that string to be the character ®.

Based on this revision history, the following works for the string "MS", but not for special characters:

@echo off
setlocal disableDelayedExpansion
for /f "usebackq tokens=*" %%i in (`dir /a:-d /b /s *.zip ^| findstr /v MS` ) do (
  echo del /s /q %%i
)
endlocal

Answer 1

# ®
$specialChar = [char]0x00AE
Get-ChildItem -File -Recurse | Where-Object {!$_.FullName.Contains($specialChar)} | Remove-Item

For older versions of PowerShell that does not support the -File parameter, use:

Get-ChildItem -Recurse | Where-Object {!$_.FullName.Contains($specialChar) -and -not $_.PSIsContainer} | Remove-Item

Answer 2

• Update - Using Powershell:

---

Get-childitem -re . | Where-Object {$_ -NotMatch '(?:®)'}|remove-item -recurse -force -Confirm:$false

# Or, by using alias #
gci -re . | ? {$_ -NotMatch '(?:®)'}| rd -re -force -Confirm:$false

• There also, can be more short cmd/bat:

---

:: in command line :: 
chcp 1252 >nul & for /f "tokens=*" %i in ('dir /a:-d /b /s *.zip ^|find /v "®"')do echo=del /q /f "%~fi"

:: in cmd/bat file ::
@echo off && >nul chcp 1252

for /f "tokens=*" %%i in ('dir /a:-d /b /s *.zip ^|find /v "®"')do echo=del /q /f "%%~fi"

• My previous answer with whose probable use is doubtful, but work too!:

  ---

---

@echo off & >nul chcp 1252 

for /f "tokens=*" %%i in ('dir /a:-d /b /s *.zip')do (
    echo/"%%~i"|find "®">nul||echo=del /q /f "%%~fi" )

Or in commandline ::

>nul chcp 1252 && for /f "tokens=*" %i in ('dir /a:-d /b /s *.zip')do @echo="%~fi"|find "®">nul||@echo=del /q /f "%~fi"

Obs.: To add ® in your code, try...

• Press and holding the alt (left) + (num pad) 1 6 9

---

---

Maybe this can help?

---

In fact the special console character, where it activates the page and encodes it used to write / read the file name, and moves that information to variables, read and compare it all in alphabet soup, is a bit difficult to handle in cmd/bat, which is why I asked for help for a language...

Therefore, for a paranoid proposal, considering actions for delete files, I took C# to try implemented a comparison using base64 for string (wildcard alt 169 = ®).

---

• Obs.: 169 = ® and differs from the 0169 = ©

---

The resulted from these actions, is a script cmd/bat, that at run time compiles the one C# sources into a executable, that will be used by script, to get string from file name, whether the character name is present (in base64) in the name.

Is this my friend, or, is something completely different from exposed above, and, that my English limited prevent me to explain to you clearly :)

Answer 3

Batch is not unicode compatible so it recognizes ® as © so I just changed ® with © in the batch file but I guess changing the code page with chcp also works. Do you want to delete all files that don't have the ® in the name or only zip files? Well if it's all files just change *.zip to * in the for:

@echo off
Title Delete all files that don't have © in Name
setlocal EnabledelayedExpansion

Rem Specify the path to the folder here:
set Folder=%userprofile%\desktop\test

for /r %Folder% %%a in (*.zip) do (
set Character=%%a
set Character=!Character:©=!
IF "!Character!"=="%%a" del /a /f "%%a"
)
pause
