• extract the .zip file and run the application by double clicking TumblThree.exe.
• Copy the url of any tumblr.com blog you want to backup from into the textbox at the bottom left. Afterwards, click on 'Add Blog' on the right side of it.
• Alternatively, if you copy (ctrl-c) a whole tumblr.com blog url from the address bar/a text file, the clipboard monitor from TumblThree will detect it and automatically add the blog.
• To start the download process, click on 'Crawl'. The application will regularly check for (new) blogs in the queue and start processing them, until you stop the application by pressing 'Stop'. So, you can either add blogs to the queue via 'Add to Queue' or double click first and then click 'Crawl', or you start the download process first and add blogs to the queue afterwards.
• A light blue bar left to the blog in the queue indicates a actively downloading blog.
• The blog manager on the left side also indicates the state of each blog. A red background shows an offline blog, a green background an actively crawling blog and a purple background an enqueued blog.
• You change the download location, the number of parallel connections, the default backup settings for each newly added blog and various other settings in the 'Settings'.
• In the Details window you can view statistics of your blog and set blog specific options. You can here what kind of post type (photo, video, audio, text, conversation, quote, link) to download.
• For downloading only tagged posts, you'll have to do some steps:
  1. Add the blog url.
  2. Open the blog in the details tab, enter the tags in the Tags textbox in a comma separated list without the leading hash (#) sign. E.g. great big car,bears would search for images that are tagged for either a great big car or bears or both.
• For downloading password protected blogs, you'll have to do some steps:
  1. Add the blog url.
  2. Open the blog in the details tab, enter the password in the Password textbox.
• For downloading hidden blogs (login required blogs), you have to do some steps:
  1. Go to Settings, click the Authenticate button. Logon to tumblr using an account. The window/browser should automatically close after the login indicating a successful authentication. TumblThree will use the Internet Explorer cookies for authentication. Alternatively, you can also use the Internet Explorer directly for logging in to the Tumblr.com network.
  2. Add the blog url.
• For downloading liked photos and videos, you'll have to do some steps:
  1. Go to Settings, click the Authenticate button. Logon to tumblr using an account. The window/browser should automatically close after the login indicating a successful authentication. TumblThree will use the Internet Explorer cookies for authentication. Alternatively, you can also use the Internet Explorer directly for logging in to the Tumblr.com network.
  2. Add the blog url including the liked/by string in the url (e.g. https://www.tumblr.com/liked/by/wallpaperfx/).
  3. For downloading your own likes, make sure you've (temporarily) enabled the following options in your blogs settings (i.e. https://www.tumblr.com/settings/blog/yourblogname):
     • Likes -> Share posts you like (to enable the publicly visible liked/by page)
     • Visibility -> blog is explicit (to see/download NSFW likes)
• For downloading photos and videos from the tumblr search, you'll have to do some steps:
  1. Add the search url including your key words separated by plus signs (+) in the url (e.g. https://www.tumblr.com/search/my+special+tags).
• For downloading photos and videos from the tumblr tag search, you'll have to do some steps:
  1. Go to Settings, click the Authenticate button. Logon to tumblr using an account. The window/browser should automatically close after the login indicating a successful authentication. TumblThree will use the Internet Explorer cookies for authentication. Alternatively, you can also use the Internet Explorer directly for logging in to the Tumblr.com network.
  2. Add the search url including your tags separated by plus signs (+) in the url (e.g. https://www.tumblr.com/tagged/my+special+tags).
• Key Mappings:
  • double click on a blog adds it to the queue
  • drag and drop of blogs from the manager (left side) to the queue.
  • space -- start crawl
  • ctrl-space -- pause crawl
  • shift-space -- stop crawl
  • del -- remove blog from queuelist
  • shift-del -- remove blog from blogmanager.
  • ctrl-shift-g -- manually trigger the garbage collection

The default settings should cover most users. You should only have to change the download location and the kind of posts you want to download. For this, in the Settings (click on the Settings button in the lower panel of the main user interface) you might want to change:

• General -> Download location: Specifies where to download the files. The default is in a folder Blogs relative to the TumblThree.exe
• Blog -> Settings applied to each blog upon addition:
  • Here you can set what posts newly added blogs will download per default. To change what each blog downloads, click on a blog in the main interface, select the Details Tab on the right and change the settings. This separation allows to download different kind of post for different blogs. You can change the download settings for multiple existing blogs by selecting them with shift+left click for a range or ctrl-a for all of them.
  • Note: You might want to always select:
    • Download Reblogged posts: Downloads reblogs, not just original content of the blog author.
    • Force Rescan: Force Rescan always crawls the whole blog and not just new posts which were added after the last successful crawl. The statistics of a blog (total posts, number of post, number of duplicates) currently can only be updated if the whole blog is crawled. Thus, disabling this might result in downloading "more" posts than displayed in TumblThree. If you don't care about the displayed blog statistics, turning Force Rescan off will decrease the scanning time since already downloaded posts are skipped in the scanning.

Settings you might want to change if the download speed is not satisfactory:

• Connection -> Concurrent connections: Specifies the number of connections used for downloading posts. The number is shared between all actively downloading blogs.
• Connection -> Concurrent video connections: Specifies the number of connections used for downloading tumblr video posts. The vt.tumblr.com host regularly closes connections if the number is too high. Thus, the maximum number of vt.tumblr.com connections can be specified here independently.
• Connection -> Concurrent blogs: Number of blogs to download in parallel.

Most likely you don't have to change any of the other connection settings. In particular, settings you should never change, unless you're sure you know what you are doing:

• Connection -> Limit Tumblr Api Connections: Leave this checkbox checked and do not change the corresponding values of 90 connections per 60 seconds. If you still change them, you might end up with offline blogs or missing downloads.

• Note: All the follwing files are stored in json format and can be opened in any editor.
• Application settings are stored in C:\Users\Username\AppData\Local\TumblThree\.
• You can use the portable mode (settings->general) to stores the application settings in the same folder as the executable.
• For each blog there is also a database (serialized class) file in the Index folder of the download location named after the blogname.tumblr. Here blog relative information is stored like what files have been downloaded, the url of the blog and when it was added. This allows you to move your downloaded files (photos, videos, audio files) to a different location without interfering with the download process.
• Some settings aren't hooked up to the graphical user interface. It's possible to view all TumblThree settings by opening the settings.json in any editor located in C:\Users\Username\AppData\Local\TumblThree\. Their names should be self explainatory. Some notable settings to further fine tune the application include:
  • BufferSize: Allows to set the buffer size for downloading binary files (photos, videos) in multiples of 4KB. The default is 2MB, thus the BufferSize has a value of 512. Increasing this value reduces disk fragmentation as more of the file is kept in the memory before it gets written out to the disk but increases the memory usage.
  • MaxNumberOfRetries: Sets the maximum number of retries if a tumblr server forcefully closes the connection. This might regularly happen on the tumblr video host (vt.tumblr.com) if too many connections were opened in parallel. After the limit is exhausted, the file is left truncated, but is also not registered as a successful downloaded. Thus, the file can be resumed in the next crawl.
  • TumblrHosts: Contains a list of hosts which is tried for downloading _raw photos if the photo size is set to raw. If none of the hosts contains the _raw version, the actually scanned host is tried with the next lower resolution (1028).

• The old datasets from TumblTwo and TumblOne are not compatible.
• No more support for Windows XP.

• Download Visual Studio. The minimum required version is Visual Studio 2015 (C# 6.0 feature support). You also need Blend for Visual Studio SDK for .NET which includes the System.Windows.Interactivity and Microsoft.Expression.Interactions .dlls.
• Download the source code as .zip file or use the GitHub Desktop and checkout the code.
• Open the TumblThree.sln solution file in the src/ directory of the code.
• Build the Source once before editing anything. Build->Build Solution.

• If you want to help translate TumblThree, there are two resource files (.resx) which contain all the strings used in the application. One for the user interface and one for the underlying application.
• Translate all the words or its meanings between the two value tags and create a pull request on github or simply send me the files via email.

• See the Wiki page for ideas of new or missing features and add your thoughts.
