Hi,
If you're using an earlier release than jmp10 (for windows), you can in your script create a .bat file and also call this .bat to delete files.
===================================================
/* Create a .bat file command with delete instruction */
Save Text File("C:\deletemyfile.bat","del C:\myfolder\myfile.txt");
/* Execute the .bat file in order to delete the file */
Open("C:\deletemyfile.bat");
===================================================
