Folder Manager (REST)

The Folder Manager service available in the REST API supports multiple operations for manipulating folder structures in the Relativity UI framework. You can use it to create, update, or move a folder, query for folders, retrieve the root or children in a folder tree, and delete empty folders. It also indicates the progress for the deletion operation on folders.

You can also use the Relativity Services API to create, update, delete, and query for folders. For more information, see Folder Manager (.NET).

Client code sample

To interact with the Folder Manager service, you send HTTP(S) requests that use the POST method and specify query conditions in the body of the request. See the base URL for this service:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/

You can use the following .NET code as the REST client for performing any of the operations available on the Folder Manager service. The code currently illustrates how to create a new folder, but you can modify it as follows to perform other operations:

Set the url variable to the URL for the operation that you want to perform.
Set the string represented by payload variable to the JSON input required for your operation.

    {
        httpClient.BaseAddress = new Uri("http://localhost/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/");

        //Set the required headers.
        httpClient.DefaultRequestHeaders.Add("/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/QueryAsync", string.Empty);
        httpClient.DefaultRequestHeaders.Add("Authorization", "Basic c2FtcGxlYWRtaW5AcmVsYXRpdml0eS5yZXN0OlMwbTNwQHNzdzByZA==");

        string url = "CreateSingleAsync";

        var workspaceArtifactId = 0;

        var payload = @"{
                    workspaceArtifactID:0,
                    model: {
                        name: 'New folder name',
                        parentFolder: {
                            artifactId: 151561
                        }
                    }";
        var result = await httpClient.PostAsJsonAsync(url, payload);
    }
}

HTTP headers and status codes

The Folder Manager Service uses the same HTTP(S) headers and status codes as other services in the Relativity REST API. For more information, see the following:

Create a folder

To create a folder, send a request to this URL for the Folder Manager service:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/CreateSingleAsync

The request includes the following fields:

workspaceArtifactID – the Artifact ID of the workspace where you want to create the folder.
name – the model name, which is the name of the Folder DTO that you want to create.
parentFolder – this field contains the parent folder where you want to add the new subfolder. If you want to create a folder at the root of a workspace, omit the parentFolder property.

The following request results in the creation of a child folder called MyFolder, which is added under an existing parent folder in a workspace.

    "model": {
        "name": "MyFolder",
        "parentFolder": {
            "artifactId": "1003697"
        }
    }
}

The response returns the Artifact ID of the folder that was created.

Update a folder

To rename or move a folder, send a request to this URL for the Folder Manager service:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/UpdateSingleAsync

The request must contain the following fields:

workspaceArtifactID – the unique identifier for the workspace where the folder resides.
model.artifactID – the unique identifier for the Folder DTO.
model.name – the text for the new folder name.

If the requests contains an Artifact ID that differs from ID for the original parent folder, the folder is moved to the parent folder specified in the request. If a parent folder isn't specified, the folder is moved to the root folder of the workspace.

The following request updates the name of folder to My new folder name. This folder has a parent folder in the workspace.

        "parentFolder": {
            "artifactId": 1003697
        },
        "name": "My new folder name"
    }
}

The response returns the Artifact ID of the folder that was updated.

Delete unused folders

To delete all empty folders in a workspace, send a request to this URL for the Folder Manager service:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/DeleteUnusedFoldersAsync

The DeleteUnusedFoldersAsync() method removes all unused folders from the workspace.

The request must include the Artifact ID of the workspace, where you want to deleted the unused folders:

Copy

{
    "workspaceArtifactID": 1015024

Query for folders

To get an unstructured list of folders, send a request to the following Folder Manager Service URL:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/QueryAsync

The request includes the following fields:

workspaceArtifactId – the Artifact ID of the workspace that you want to query.
query – may include query conditions or may be an empty query as illustrated in the following sample.
length – indicates the number of returned results. The default value is 0 for length, and the number of returned results defaults to the Instance setting table value of PDVDefaultQueryCacheSize of 10000.

Copy

1
2
3

5
{
    "workspaceArtifactId": 1015024,
    "query": {},
    "length": 2
}

The response returns a list of all folders in the workspace that are available to requesting user.

View the JSON response for a query

If the response contains a token value that isn't null, it indicates that more results are available than initially specified in the length property, or that result count exceeds the default query limit. You can retrieve the additional folders by using the QuerySubsetAsync() method as illustrated in the following URL:

Copy

1
/Relativity.Rest/API/Relativity.Services.Folder.IFolderModule/Folder%20Manager/QuerySubsetAsync

The request for this method must include the workspaceArtifactID, queryToken, start, and length as in the following sample query:

{
    "workspaceArtifactID": 1015024,

    "start": 5,
    "length": 4
}

The response to this query returns a subset with four elements from the previous query that starts at the fifth element.

Retrieve expanded Folder nodes

You can retrieve a folder structure that contains expanded nodes, or you can retrieve a folder structure that contains expanded nodes, and Artifact ID of the folder currently selected by a user.

For example, you might want to retrieve information about the children of the expanded root folder called Relativity Starter Template illustrated in the following screen shot:

sample folder hierarchy

You would query on Relativity Starter Template, Folder 3, and Folder 3.2 by sending the following request:

For more information about the starter templates, see Starter template on the RelativityOne Documentation site.
