-### --fast-list ###
-
-This remote supports `--fast-list` which allows you to use fewer
-transactions in exchange for more memory. See the [rclone
-docs](/docs/#fast-list) for more details.
-
-It does this by combining multiple `list` calls into a single API request.
-
-This works by combining many `'%s' in parents` filters into one expression.
-To list the contents of directories a, b and c, the the following requests will be send by the regular `List` function:
-```
-trashed=false and 'a' in parents
-trashed=false and 'b' in parents
-trashed=false and 'c' in parents
-```
-These can now be combined into a single request:
-```
-trashed=false and ('a' in parents or 'b' in parents or 'c' in parents)
-```
-
-The implementation of `ListR` will put up to 50 `parents` filters into one request.
-It will  use the `--checkers` value to specify the number of requests to run in parallel.
-
-In tests, these batch requests were up to 20x faster than the regular method.
-Running the following command against different sized folders gives:
-```
-rclone lsjson -vv -R --checkers=6 gdrive:folder
-```

-
-Paths are specified as `remote:path`
-
-Paths may be as deep as required, eg `remote:directory/subdirectory`.
-
-To configure Jottacloud you will need to enter your username and password and select a mountpoint.
-
-Here is an example of how to make a remote called `remote`.  First run:
-
-     rclone config
-
-This will guide you through an interactive setup process:
-
-```
-No remotes found - make a new one

-pass = *** ENCRYPTED ***
-mountpoint = Archive
--------------------
-y) Yes this is OK
-e) Edit this remote
-d) Delete this remote
-y/e/d> y

-Once configured you can then use `rclone` like this,
-
-List directories in top level of your Jottacloud
-
-    rclone lsd remote:
-
-List all the files in your Jottacloud
-
-    rclone ls remote:
-
-To copy a local directory to an Jottacloud directory called backup
-
-    rclone copy /home/source remote:backup
-
-
-### Modified time and hashes ###
-
-Jottacloud allows modification times to be set on objects accurate to 1
-second.  These will be used to detect whether objects need syncing or
-not.
-
-Jottacloud supports MD5 type hashes, so you can use the `--checksum`
-flag.
-
-Note that Jottacloud requires the MD5 hash before upload so if the
-source does not have an MD5 checksum then the file will be cached
-temporarily on disk (wherever the `TMPDIR` environment variable points
-to) before it is uploaded.  Small files will be cached in memory - see
-the `--jottacloud-md5-memory-limit` flag.
-
-### Deleting files ###
-
-Any files you delete with rclone will end up in the trash. Due to a lack of API documentation emptying the trash is currently only possible via the Jottacloud website.
-
-### Versions ###
-
-Jottacloud supports file versioning. When rclone uploads a new version of a file it creates a new version of it. Currently rclone only supports retrieving the current version but older versions can be accessed via the Jottacloud Website.
-
-### Limitations ###
-
-Note that Jottacloud is case insensitive so you can't have a file called
-"Hello.doc" and one called "hello.doc".
-
-There are quite a few characters that can't be in Jottacloud file names. Rclone will map these names to and from an identical looking unicode equivalent. For example if a file has a ? in it will be mapped to ？ instead.
-
-Jottacloud only supports filenames up to 255 characters in length.
-
-### Specific options ###
-
-Here are the command line options specific to this cloud storage
-system.
-
-#### --jottacloud-md5-memory-limit SizeSuffix
-
-Files bigger than this will be cached on disk to calculate the MD5 if
-required. (default 10M)
-
-### Troubleshooting ###
-
-Jottacloud exhibits some inconsistent behaviours regarding deleted files and folders which may cause Copy, Move and DirMove operations to previously deleted paths to fail. Emptying the trash should help in such cases.
