DelAn internal DOS/Windows command that erases a file from the disk. When a file is deleted from the command line, it cannot be retrieved from the recycle bin, so "be careful!" However, files deleted from Windows Explorer are saved in the recycle bin. Del and Erase are two forms of the command. See Delete key.
Following are examples of deleting single and multiple files:
del old.txt erase OLD.TXT del *.txt erase all TXT files or erase old.txt erase OLD.TXT erase *.txt erase all TXT files
