ASCII_Read + ASCII_Save

Reads and saves text file giving its full name
Used a lot in my tools, very handy tool
ReadMethod ...
'    =1, reads/saves using ADODB stream, used for UTF-8 Unicode files.
'    =2, reads/saves using FileSystemObject, does not work with UTF-8
'    =3, reads using 'Open+Input all bulk', Saves using 'Output'
'    =4, reads using 'Open+Input line by line', saves using 'Append'

Edit: 2020-10-13: Adding ability to avoid error if file is 0 bytes length when reading
