How to delete all files and directories with an exception

Question

I have a few files and directories, (all directories contain files):

C:\\ABC
│   file1.txt
│
├───folder1
│       oneormorefiles.ext
│
├───folder2
│              


        

Answer 1

I would suggest this as a possibile alternative to using FOR loop and/or a mixture of DEL and RD:

MD "%TEMP%\$_.dummy"&&ROBOCOPY "%TEMP%\$_.dummy" "C:\abc" /E /XD logs /PURGE>NUL 2>&1&RD "%TEMP%\$_.dummy"
