iMacros: "FILEDELETE NAME=file_name" does'n work

I'm trying to make an iMacros script that saves the last loop, in case iMacros gives an error. All god, but FILEDELETE NAME=file_name does'n work for me. I tried different ways, I end up changing the original folders, but still not working.

I have this error:

SyntaxError: unknown command: FILEDELETE at line 11

SET !FOLDER_DOWNLOAD D:\IMACROS\DOWNLOADS
SET !FOLDER_DATASOURCE D:\IMACROS\DOWNLOADS
SET !DATASOURCE RELEASE769.csv
SET !DATASOURCE_LINE 1
SET !LOOP {{!COL1}}
SET LASTLOOP EVAL("{{!COL1}}+1")

 
 
'FILEDELETE NAME=RELEASE769.csv
FILEDELETE NAME=D:\IMACROS\DOWNLOADS\RELEASE769.csv

WAIT SECONDS=1
ADD !EXTRACT {{LASTLOOP}}
ADD !EXTRACT {{!NOW:yyyy-mm-dd<SP>La<SP>ora:<SP>hh<SP>si<SP>nnmin}}

'SAVEAS TYPE=EXTRACT FOLDER=* FILE=RELEASE769
SAVEAS TYPE=EXTRACT FOLDER=D:\IMACROS\DOWNLOADS FILE=RELEASE769

I am using (FCI): iMacros for CR v10.1.1 'PE', CR v105.0.5195.102 (_x64), Win10_x64. ('CR' = 'Chrome' / 'PE' = 'Personal Edition')

Thank you so much for support
