B4J Library FileUtils

I hope it can be useful.
I'm using this library a lot of in my application.

It depends on:
- ByteConverter
- Encryption
- JavaObject​

      • Exist (Path As Path) As Boolean
      • GetChecksum (Folder As String, FileName As String, Algorithm As String) As String
        Algorithm can be "MD5", "SHA-1", "SHA-224", "SHA-256", "SHA-384" or "SHA-512"

      • RenameTo (Folder As String, FileName As String, NewFileName As String) As String
      • SaveFile (Frm As Form, Filters As Map, AllFilters As Boolean, MergeFilters As Boolean, MergeName As String, InitialFileName As String, Title As String) As Path
        Returns uninitialized Path if a destination is not chosen
      • Size (Path As Path) As Long
  • Path
    • Fields:
      • FileName As String
      • Folder As String
