I would do it differently.

lcFileName = "..."
IF FILE(lcFileName)
  .txtbxdefault.Value = FILETOSTR(lcFileName)
ELSE
  STRTOFILE("", lcFileName)
ENDIF

I's also not a good idea to store any files in the root of C: drive.

>        IF nSize > 0
>            = FSEEK(gnFileHandle, 0, 0)      && Move pointer to BOF
>            .txtbxdefault.Value = Alltrim(FREAD(gnFileHandle, nSize))
>        ENDIF
>    ENDIF
>    = FCLOSE(gnFileHandle)
