Upload using Workbench -The Arvados distributed file system is called *Keep*. Keep is a content-addressable file system. This means that files are managed using special unique identifiers derived from the _contents_ of the file, rather than human-assigned file names (specifically, the md5 hash). This has a number of advantages: -* Files can be stored and replicated across a cluster of servers without requiring a central name server. -* Systematic validation of data integrity by both server and client because the checksum is built into the identifier. -* Minimizes data duplication (two files with the same contents will result in the same identifier, and will not be stored twice.) -* Avoids data race conditions (an identifier always points to the same data.) +To upload using Workbench, visit the Workbench *Dashboard*. Click on *Projects* dropdown menu in the top navigation menu and select your *Home* project or any other project of your choosing. You will see the *Data collections* tab for this project, which lists the collections in this project. -h1.

-Use @arv keep get@ to download the contents of a collection and place it in the directory specified in the second argument (in this example, @.@ for the current directory):
 
-
-
/scratch/you$ arv keep get c1bad4b39ca5a924e481008009d94e32+210/ .
-

-
+The output value @zzzzz-4zz18-xxxxxxxxxxxxxxx@ is the uuid of the Arvados collection created.
 
-You can also download indvidual files:
+Note: The file used in this example is a freely available TSV file containing variant annotations from the "Personal Genome Project (PGP)":http://www.pgp-hms.org participant "hu599905":https://my.pgp-hms.org/profile/hu599905), downloadable "here":https://warehouse.pgp-hms.org/warehouse/f815ec01d5d2f11cb12874ab2ed50daa+234+K@ant/var-GS000016015-ASM.tsv.bz2. Alternatively, you can replace @var-GS000016015-ASM.tsv.bz2@ with the name of any file you have locally, or you could get the TSV file by "downloading it from Keep.":{{site.baseurl}}/user/tutorials/tutorial-keep-get.html

/scratch/you$ arv keep get 887cd41e9c613463eab2f0d885c6dd96+83/alice.txt .

-
-With a local copy of the file, we can do some computation, for example computing the md5 hash of the complete file:
+It is also possible to upload an entire directory with @arv-put@:
 
 
-
/scratch/you$ md5sum var-GS000016015-ASM.tsv.bz2

-h2. Using arv-mount
+In both examples, the @arv-put@ command created a collection. The first collection contains the single uploaded file. The second collection contains the entire uploaded directory.
 
-Use @arv-mount@ to take advantage of the "File System in User Space / FUSE":http://fuse.sourceforge.net/ feature of the Linux kernel to mount a Keep collection as if it were a regular directory tree.
+@arv-put@ accepts quite a few optional command line arguments, which are described on the "arv subcommands":{{site.baseurl}}/sdk/cli/subcommands.html#arv-keep-put page.

+Visit the Workbench *Dashboard*.  Click on *Projects* dropdown menu in the top navigation menu, select your *Home* project.  Your newly uploaded collection should appear near the top of the *Data collections* tab.  The collection name printed by @arv-put@ will appear under the *name* column.
 
-Using @arv-mount@ has several significant benefits:
+To move the collection to a different project, check the box at the left of the collection row.  Pull down the *Selection...* menu near the top of the page tab, and select *Move selected...* button. This will open a dialog box where you can select a destination project for the collection.  Click a project, then finally the Move button.
 
-* You can browse, open and read Keep entries as if they are regular files.
-* It is easy for existing tools to access files in Keep.
-* Data is downloaded on demand, it is not necessary to download an entire file or collection to start processing
+!{display: block;margin-left: 25px;margin-right: auto;}{{ site.baseurl }}/images/workbench-move-selected.png!
 
-

+Click on the * Show* button next to the collection's listing on a project page to go to the Workbench page for your collection.  On this page, you can see the collection's contents, download individual files, and set sharing options.
