Accesses the FME Flow file storage service to upload, download, or delete files and folders or list information about files/folders from an FME Flow account.
Typical Uses
- Access data stored on FME Flow file storage without using FME Flow
- Manage datasets on FME Flow by uploading, downloading, and deleting files and folders
- Transfer a file's contents (such as XML or raster) into or out of an attribute in FME
- Read downloaded data using the FeatureReader, or upload data written by the FeatureWriter to FME Flow
- Retrieve file and folder names, paths, and other information from FME Flow to use elsewhere in a workspace.
How does it work?
Depending on your choice of actions, it will upload or download files, folders, and attributes; list information from the service; or delete items from the service. On uploads, path attributes are added to the output features. On List actions, file/folder information is added as attributes.
Usage Notes
- This transformer cannot be used to directly move or copy files between different FME Flow file storage locations. However, multiple FMEFlowResourceConnectors can be used to accomplish these tasks.
- The FeatureReader can access FME Flow file storage directly (without using the FMEFlowResourceConnector), however, a local copy of the dataset will not be created.
Configuration
Input Ports
Input
This transformer accepts any feature.
Output Ports
Output
The output of this transformer will vary depending on the FME Flow Action performed.
- An Upload action will save the path of the file to an attribute.
- A Download action can save to either a folder or attribute.
- A Delete action has no output ports.
- Finally, a List action will output a new feature for each file/folder found in the path specified. Each of these new features will have attributes listing various pieces of information about the object.
<Rejected>
Features that cause the operation to fail are output through this port. An fme_rejection_code attribute, having the value ERROR_DURING_PROCESSING, will be added, along with a more descriptive fme_rejection_message attribute which contains more specific details as to the reason for the failure.
Rejected Feature Handling: can be set to either terminate the translation or continue running when it encounters a rejected feature. This setting is available both as a default FME option and as a workspace parameter.
Parameters
Request
|
FME Flow Action |
The type of operation to perform. Choices include:
|
|
FME Flow Account |
Performing operations against an FME Flow account requires the use of OAuth2 authentication using a web connection. For more information, see Using Web Connections. SAML Authentication SAML (Security Assertion Markup Language) authentication is not available for these FME Flow transformers: See SAML Configuration and Automations for more information and alternatives. |
The remaining parameters available depend on the value of the FME Flow Action parameter. Parameters for each FME Flow Action are detailed below.
Parameters - Delete Action
FME Flow Path
|
Object |
The file or folder on FME Flow to delete. If valid credentials have been provided as a web connection, you may browse to a location. |
Parameters - Download Action
FME Flow Source
|
Object |
The FME Flow path of the file/folder to download. If valid credentials have been provided as a web connection, you may browse to a location. |
Destination
|
Download as |
Select whether to store the downloaded data in a File, Folder or Attribute.
|
|
Download to Folder |
Specify the path to the folder that will store the downloaded file. Valid for Download as File or Folder. |
|
Include Subfolders |
Choose whether to download subfolders of the FME Flow Source or not. Valid for Download as Folder only. |
|
Download to Attribute |
Specify the attribute that will store the contents of the downloaded file. Valid for Download as Attribute only. Note FME will attempt to convert the attribute's contents to a UTF-8 string. If this fails, the attribute's contents will be created as raw binary. To ensure that the original bytes are always preserved and never converted to UTF-8, use Download as File instead.
|
Parameters - List Action
FME Flow Path
|
Folder |
The folder on FME Flow to list the contents of. If valid credentials have been provided as a web connection, you may browse to a location. |
Output Attributes
|
Attributes to Add |
The selected attributes will be added to the output feature.
|
Parameters - Upload Action
Source
|
Upload |
The source of the data to be uploaded. File: The specified file will be uploaded. Folder: The specified folder and its contents will be uploaded. Attribute: The contents of the specified attribute will be uploaded. When working with large objects, File is a better choice than Attribute as the data will be streamed directly from disk and not require that the object be stored entirely in memory on a feature. FME Flow treats file uploads of the same name, in a specific folder, as duplicates, and will automatically overwrite a file if it exists in the same folder. When wanting to upload content from a folder, it is better to upload as a folder instead of setting a fixed path and sending multiple features into the connector to upload as a file. |
|
File to Upload |
The file to be uploaded to FME Flow if Upload is set to File. |
|
Folder to Upload |
The folder to be uploaded to FME Flow if Upload is set to Folder. |
|
Include Subfolders |
Choose whether to upload subfolders of the Folder to Upload or not. |
|
Attribute to Upload as File |
The data to be uploaded, supplied from an attribute if Upload is set to Attribute. |
FME Flow Destination
|
Folder |
The path on FME Flow to upload the source file to. You must choose a specific shared resource folder to upload your content to. |
|
Upload with File Name |
The name of the file created from the data supplied in Attribute to Upload as File. The name must include a filename extension (for example, .txt, .jpg, .doc). |
Output Attributes
|
Attributes to Add |
The selected attributes will be added to the output feature.

Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
How to Set Parameter Values
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
|
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |
Dialog Options - Tables
Transformers with table-style parameters have additional tools for populating and manipulating values.
Table Tools
|
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
|
Filter
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
|
Import
|
Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
|
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note: Not all tools are available in all transformers.
