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​

  • Fields:
    • initialFilterDescription As String
      
    • initialFolder As String
  • Functions:
    • ChooseFile (Frm As Form, Filters As Map, AllFilters As Boolean, MergeFilters As Boolean, MergeName As String, Title As String) As Path
      Returns uninitialized Path if a destination is not chosen
      <code> Dim filters As Map = CreateMap( Array As String("*.txt") : "TXT File", _
      Array As String("*.xml") : "XML File", _
      Array As String("*.html", "*.htm") : "Hyper Text")</code>
    • ChooseFolder (Frm As Form, Title As String, InitialDir As String) As Path
      Returns uninitialized Path if a destination is not chosen
    • ChooseMultipleFiles (Frm As Form, Filters As Map, AllFilters As Boolean, MergeFilters As Boolean, MergeName As String, Title As String) As List
      Returns uninitialized Path if a destination is not chosen
    • Combine (Path As Path) As String
      
    • Copy (DirSource As String, FileSource As String, DirTarget As String, FileTarget As String) As String

    • CopyAsync (DirSource As String, FileSource As String, DirTarget As String, FileTarget As String) As ResumableSub
      Similar to File.CopyAsync() but also folders with content can be copied
    • CreatePath (Folder As String, FileName As String) As Path
      
    • CreatePath2 (CompletePath As String) As Path
      
    • Delete (Folder As String, FileName As String) As String
      Similar to File.Delete() but also folders with content can be deleted
    • EqualFile (Source1 As String, FileName1 As String, Source2 As String, FileName2 As String, Algorithm As String) As Boolean
      Check through the checksum algorithm if two files are equal.
      Algorithm = "MD5", "SHA-1", "SHA-224", "SHA-256", "SHA-384", "SHA-512"
    • 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"
    • GetExtension (FileName As String) As String
      Return file extension
      Ex.
      FileUtils.GetExtension("test.txt") <---- Returns ".txt"
    • GetFiles (FolderPath As String) As List

      The list will not contain RootFolder
    • IsDirectory (Path As Path) As Boolean
      
    • LastModified (Path As Path) As Long
      
    • MakeDir (Path As Path) As String
      
    • OpenFile (Folder As String, FileName As String) As String
      
    • OpenFile2 (CompletePath As String) As String
      
    • Process_Globals As String
      
    • RemoveExtension (FileName As String) As String
      Return a new string without extension
    • 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
      
    • IsInitialized As Boolean
      Tests whether the object has been initialized.
