I was able to delete the network file share with periodic task with the following batch. my problem is solved, but if there are any suggestions about the method or different, I can take it.
@ECHO OFF
SET THEDIR=path-to-folder
Echo Deleting all files from %THEDIR%
DEL "%THEDIR%\*" /F /Q /A
Echo Deleting all folders from %THEDIR%
FOR /F "eol=| delims=" %%I in ('dir "%THEDIR%\*" /AD /B 2^>nul') do rd /Q /S "%THEDIR%\%%I"
@ECHO Folder deleted.
EXIT
