-    The access() function checks the file, named by the pathname pointed to by\r
-    the Path argument, for accessibility according to the bit pattern contained\r

-\r
-    The value of Mode is either the bitwise-inclusive OR of the access\r
-    permissions to be checked (R_OK, W_OK, X_OK) or the existence test (F_OK).\r

-    If Path ends in '/' or '\\', the target must be a directory, otherwise it doesn't matter.\r
-    A file is executable if it is NOT a directory and it ends in ".efi".\r
