delete data from flash in MDBT42?

VERSION: "2v04", GIT_COMMIT: "3956264e", BOARD: "MDBT42Q",
FLASH: 524288, RAM: 65536, SERIAL: "3700071-fa641234", CONSOLE:
"Serial1", MODULES: "Flash,Storage,hea" ... "S,crypto,neopixel",
EXPTR: 536882364 }

var res=process.memory();
 console.log("Memory free - " + res.free);
 if(res.free<2000)
 {
   LED1.write(true);
   console.log(ScanResault);
   require("Storage").write("Test",JSON.stringify(ScanResault));
   console.log("write");
   GetData = JSON.parse(require("Storage").read("Test"));
   console.log("JSON.parse");
   ScanResault.length=0;
   console.log("Clear Array finsih");
   console.log(ScanResault.length);
  }

when I run the code
I get error that

Uncaught Error: Unable to find or create file
 at line 35 col 63
...JSON.stringify(ScanResault));
                              ^
in function called from system
> 

but when I run list I can see the file

console.log(require("Storage").list());
[
  "Test",
  ".varimg"
 ]
=undefined

maybe this is my problem?

and how could it be ?
