Files from the user’s computer can be uploaded into the storage using the FileUpload and FileMultiUpload components. Usage examples are provided in this manual in the appropriate component descriptions, as well as in Loading and Displaying Images.

The temporary client-level storage (FileUploadingAPI) stores temporary files in the folder defined by cuba.tempDir application property. Temporary files can remain in the folder in case of any failures. The clearTempDirectory() method of the cuba_FileUploading bean is invoked periodically by the scheduler defined in the cuba-web-spring.xml file.
