## Description

GDataDocumentsUploadQuery is a collection of parameters for document uploads to Google Documents, allowing various options to be set when uploading a document for the first time. For example, the destination folder for the uploaded document may be specified; or whether to automatically convert the document to a common format.

GDataDocumentsUploadQuery is designed as an object (rather than a fixed struct or set of function arguments) to allow for easy additions of new Google Documents features in the future.

Example 31. Uploading an Arbitrary File from Disk

## Types and Values

### GDataDocumentsUploadQuery

    typedef struct _GDataDocumentsUploadQuery GDataDocumentsUploadQuery;

## Property Details

### The `“convert”` property

      “convert”                  gboolean

`TRUE` to automatically convert the uploaded document into a standard format (such as a text document, spreadsheet, presentation, etc.). `FALSE` to upload the document without converting it; this allows for arbitrary files to be uploaded to Google Documents.

For more information, see the

online documentation.

Note that uploading with this property set to `FALSE` will only have an effect when using `gdata_documents_service_update_document_resumable()` and not `gdata_documents_service_update_document()`. Additionally, the GDataDocumentsDocument passed to `gdata_documents_service_update_document_resumable()` must be a GDataDocumentsDocument if this property is `FALSE`, and a subclass of it otherwise.

Owner: GDataDocumentsUploadQuery

Flags: Read / Write

Default value: TRUE

Since: 0.13.0

### The `“folder”` property

      “folder”                   GDataDocumentsFolder *

Folder to upload the document into. If this is `NULL`, the document will be uploaded into the root folder.

Owner: GDataDocumentsUploadQuery

Flags: Read / Write
