      Target:  path with filename in cloud, .NET regular expression,
               see https://docs.microsoft.com/ru-ru/dotnet/standard/base-types/regular-expressions
      MinSize: minimum file size
      MaxSize: maximum file size
      -->
    <Rules>
      <!-- cache any path/file contains "EUREKA" in disk cache-->
      <Rule Cache="Disk" Target = "EUREKA" MinSize = "0" MaxSize = "0" />

      <!-- small files less than 15000000 bytes will be cached in memory -->
      <Rule Cache="Memory" Target = "" MinSize = "0" MaxSize = "15000000" />

      <!-- files larger than 15000000 bytes will be cached on disk -->
      <Rule Cache="Disk" Target = "" MinSize = "15000000" MaxSize = "0" />
    </Rules>
  </Deduplicate>

Then run with --use-deduplicate command line key.

Yandex.Disk

(download latest Release, use --protocol YadWebV2 command line key)

Yandex.Disk WebDAV issues

• It seems Yandex.Disk WebDAV is limited by speed now.
• After file uploading Yandex servers calculating hash. E.g. for a 10GB file it may take ~1..2 minutes depending on server load. So most of WebDAV clients drops connection on timeout.
• There's no WebDAV info in official help now. WTF?

This solution allow to bypass that limits using unofficial Yandex.Disk Web API.

Yandex.Disk WebDAV authentication

There are 2 ways to get into Yandex.Disk:

• Use login & password only. The option to use login & password only must be selected in account settings. In this case login (e.g. John or [email protected]) and main account password should be used in authentication fields. Do not use an Application password or any other special password generated by Yandex, the main original account password must be used. And no codes from SMS!
• Use standard browser authentication. Use the YandexAuthBrowser application. In this case you can use any available Yandex authentication including SMS and QR codes. For more details read the YandexAuthBrowser section.

YandexAuthBrowser

1. Download the package with YandexAuthBrowser.

2. Choose a folder for the program.

• The access to folder must be unrestricted for the program!
  The program writes into sub-folders, so it must have full unrestricted rights on the folder and sub-folders.
  C:\, C:\Program Files and so on is not a good choice, the program will not work properly. The better choice is "%userprofile%\AppData\Local\YandexAuthBrowser" folder.
• The folder must be secured from anyone else!
  The sub-folders contain cookies and other sensitive information for easy access any of your data inside on your Yandex.Disk!
  Please keep program sub-folders from other's dirty hands!

3. Unpack YandexAuthBrowser into selected secured folder. Run the YandexAuthBrowser.
   Choose a port number to listen to incoming authentication request on.
   Set a password or use link to generate GUID as a new password.
   Also you can test the authentication process using Test button.

4. Open wdmrc.config and edit <BrowserAuthenticator> tag (add the tag if it's missing).
   Attributes:
   Url="http://localhost:`/" - address of the PC running YandexAuthBrowser application, portmeans port number you selected on previous step in YandexAuthBrowser application.<br> Password="E86A63FC-9BF0-4351-AD51-A5F806BA38EF" - password or GUID you selected on previous step in YandexAuthBrowser application.<br> The E86A63FC-9BF0-4351-AD51-A5F806BA38EFis an example of password, use your own please. The privacy of your password prevents intruders from accessing your private data on Yandex.Disk!<br> CacheDir="full path to a secured folder" - full path to a folder with cache files containing browser cookies after authenticated access to your Yandex.Disk. This folder must be placed in restricted location. Only you and your BrowserAuthenticator must have access to the folder! __If anyone gets files from the folder he or she may easily take your data on Yandex.Disk!__ So keep the folder secured! If you do not trust or if you do not want to keep cache, keep CacheDir` attribute empty. Also you may delete any sub-folder but 'runtimes' in the BrowserAuthenticator application's folder. If you trust you PC enough, you can use a folder like "%userprofile%\AppData\Local\YandexAuthBrowser" for the cache. Replace the %userprofile% with actual path.

5. When you connect to a webdav:

• Fill the login field with short (John) or full ([email protected]) name of the account.
  
• Leave the password field empty (or put one or more spaces in case your program disallows empty passwords).
  If password is empty or space(s) only the Password from <BrowserAuthenticator> tag is used to authenticate the request to the BrowserAuthenticator program. If passwords are not matched the BrowserAuthenticator rejects the request.
  
• Fill the password field with Password taken from BrowserAuthenticator application.
  In this case the Password from <BrowserAuthenticator> tag is not used. Also you may remove Password attribute in <BrowserAuthenticator> tag.

6. Press Win+R and run shell:startup. Put shortcut of the BrowserAuthenticator program in startup folder, so the BrowserAuthenticator program will be started everytime you login the Windows. The program stays in system tray until you reboot or manually exit it using menu on tray icon.

How to use encryption

Using XTS AES-256 on-the-fly encryption/decryption

• Set (en/de)cryption password

  • with >>crypt passwd special command
    or
  • Add # and separator string to your login: [email protected]#_SEP_
  • After your mail.ru password add separator string and password for encrypting: MyLoginPassword_SEP_MyCryptingPassword

• Mark folder as encrypted using >>crypt init command

• After that files uploaded to this folder will be encrypted

Commands
Commands executed by making directory with special name.
Parameters with spaces must be screened by quotes.

• >>join SHARED_FOLDER_LINK Clone shared cloud.mail.ru file/folder to your account
• >>join #filehash filesize [/][path]filename Clone cloud.mail.ru file to your account by known hash and size
• >>link SHARED_FOLDER_LINK [linkname] Link shared folder without wasting your space (or manually edit file /item.links.wdmrc)
• >>link check Remove all dead links (may take time if there's a lot of links)
• >>move /full/path/from /full/path/to Fast move (if your client moves inner items recursively)
• >>copy /full/path/from /full/path/to Fast copy (if your client copies inner items recursively)
• >>lcopy x:/local/path/from /full/server/path/to If file already in cloud, add it by hash without uploading
• >>rlist [[/]path] [list_filename] list [path] to [list_filename]
• >>del [[/]path] Fast delete (if your client makes recursive deletions of inner items)
• >>share [[/]path] Make file/folder public
  
  • and create .share.wdmrc file with links
• >>sharev [[/]path] [resolution] Make media file public
  
  • resolution = 0p (all), 240p, 360p, 480p, 720p, 1080p
  • and create .share.wdmrc file with public and direct play links
• >>pl [[/]path] [resolution] Make media file public
  
  • resolution = 0p (all), 240p, 360p, 480p, 720p, 1080p
  • and create .share.wdmrc file with public and direct play links
    
  • and create .m3u8 playlist file
• >>crypt init Mark current folder as encrypted
• >>crypt passwd password_for_encryption_decryption Set password for encryption/decryption

Settings in wdmrc.exe.config

• Logging
  <config><log4net>
  It's standard Apache log4net configurations, take a look for examples Additionally you can use protocol and port properties taken from command-line parameters.

• Default video resolution for generated m3u playlists <config><DefaultSharedVideoResolution>
  Values: 0p auto, m3u contains links to all available resolutions 240p ~ 352 x 240 360p ~ 480 x 360 480p ~ 858 x 480 720p ~ 1280 x 720 1080p ~ 1920 x 1080

• Default User-Agent
  <config><DefaultUserAgent>
  Default user-agent for web requests to cloud.

• Special command prefix
  <config><AdditionalSpecialCommandPrefix>
  custom special command prefix instead of >>. Make possible to use special commands if client doesn't allow >>.

• Enable/disable WebDAV properties
  <config><WebDAVProps>
  set false on properties you don't need to speedup listing on large catalogs / slow connections.

• 2 Factor Authentication
  At this time you can use

  • <TwoFactorAuthHandler Name = "AuthCodeConsole"/> - asks for authcode in application console
  • <TwoFactorAuthHandler Name = "AuthCodeWindow"/> - asks for authcode in GUI window (only for .NET Framework releases)

  •  <TwoFactorAuthHandler Name = "AuthCodeFile">
     	<Param Name = "Directory" Value = "d:"/>
     	<Param Name = "FilenamePrefix" Value = "wdmrc_2FA_"/>
     </TwoFactorAuthHandler>
    

    user must write authcode to file. For example, user [email protected] writes code to d:\[email protected].

  Be careful, this methods does not usable when application started as a service/daemon.
  You can make your own 2FA handlers inherited from ITwoFaHandler and put it in separate dll which name starts with MailRuCloudApi.TwoFA

Connect with (almost any) file manager that supports WebDAV using Basic authentication with no encryption and

• your cloud.mail.ru email and password
• or anonymous login if only public links list/download required (WinSCP script example)

Automatically split/join when uploading/downloading files larger than cloud allows.

Windows

Using as windows service

• Run cmd with Administrator rights
• Then, for example, wdmrc.exe --install wdmrc -p 801 --maxthreads 15
  
• net start wdmrc

Using from explorer requires enabled Basic Auth for WebDAV

* Press Win+R, type `regedit`, click OK * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters * Right click on the BasicAuthLevel and click Modify * In the Value data box, type 2, and then click OK. * Reset computer (or run `cmd` with admin rights and then `net stop webclient`, `net start webclient`)

Use as Windows disk

``` net use ^disk^: http://^address^:^port^ ^your_mailru_password^ /USER:^your_mailru_email^ ```

Faster WebDAV Performance in Windows 7

Windows 7 client might perform very bad when connecting to any WebDAV server. This is caused, because it tries to auto-detect any proxy server before any request. Refer to KB2445570 for more information.

• In Internet Explorer, open the Tools menu, then click Internet Options.
• Select the Connections tab.
• Click the LAN Settings button.
• Uncheck the “Automatically detect settings” box.
• Click OK until you’re out of dialog.

By default, Windows limits file size to 5000000 bytes, you can increase it up to 4Gb

* Press Win+R, type `regedit`, click OK * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters * Right click on the FileSizeLimitInBytes and click Modify * Click on Decimal * In the Value data box, type 4294967295, and then click OK. * Reset computer (or run `cmd` with admin rights and then `net stop webclient`, `net start webclient`)
