Supported URL Formats for File Operations
URL attributes may be defined using the URL File Dialog.
Unless explicitly stated otherwise, URL attributes of File Operation components accept multiple URLs separated with a semicolon (';').
To ensure graph portability, forward slashes must be used when defining the path in URLs (even on Microsoft Windows).
Most protocols support wildcards:
? (question mark) matches one arbitrary character;
* (asterisk) matches any number of arbitrary characters.
Note that wildcard support and their syntax is protocol-dependent.
Below are some examples of possible URL for File Operations:
One specified file.
Two specified files.
All files satisfying the mask.
All files in the specified directory.
.txtfiles in directories that satisfy the
path/filename.txtfile on a remote server connected via an FTP protocol using username and password.
If the initial working directory differs from the server root directory, please use absolute FTP paths, see below.
/path/filename.txtfile on a remote server - the initial slash must be escaped as
%2F. The path is absolute with respect to the server root directory.
Denotes all files satisfying the mask on a remote server connected via an FTP protocol using username and password.
filename.txtfile on a remote server connected via an SFTP protocol using username and password.
Denotes all files
filename.txtin directories satisfying the mask on a remote server connected via SFTP protocol using username and password.
filename.txtfile on a remote server connected via an HTTP protocol.
filename.txtfile on a remote server connected via an HTTPS protocol.
path/filename.txtobject located in Amazon S3 web storage service in a bucket
bucketname. The connection is established using the specified access key ID and secret access key.
path/filename.txtobject located in Azure Blob Storage service in a container
containername. Connects using the specified Account Key. See Azure Blob Storage for other authentication options.
filename.txtfile on Hadoop HDFS. The "
CONNECTION_ID" stands for the ID of a Hadoop connection defined in a graph.
Denotes a file located in Windows share (Microsoft SMB/CIFS protocol). The URL path may contain wildcards (both * and ? are supported). The
serverpart may be a DNS name, an IP address or a NetBIOS name. The Userinfo part of the URL (
domain%3Buser:password) is not mandatory and any URL reserved character it contains should be escaped using the %-encoding similarly to the semicolon
%3Bin the example (the semicolon is escaped because it collides with the default CloverDX file URL separator).
The SMB version 1 protocol is implemented in the JCIFS library which may be configured using Java system properties. See Setting Client Properties in JCIFS documentation for a list of all configurable properties.
The SMB version 2 and 3 protocol is implemented in the SMBJ library.
Due to the upgrade of the SMBJ library in CloverDX version 6.2, anonymous access using SMB protocol version 2 or 3 will no longer work unless your Samba server is configured to stop requiring message signing. If turning off message signing is not an option, you can create a user without a password to use in the URL as a workaround. See below for example URLs:
A sandbox resource, whether it is a shared, local or partitioned sandbox, is specified in a graph under the fileURL attributes as a so called sandbox URL like this:
data is a code for sandbox and
path/to/file/file.dat is the path to the resource from the sandbox root.
A graph does not have to run on the node which has local access to the resource.
