Manage Files for Presto Features or Artifacts

Presto uploads and hosts files that are used as schemas for Wires, as resources or help for custom apps or custom blocks in Wires, as thumbnails, as screenshots or all file associate with a pluggable library or pluggable view library. Presto also uploads and hosts files for some types of mashables that are not accessible via HTTP (spreadsheets, CSV or XML files). These files are saved and managed in the Presto Repository to ensure better management of resources and easier deployment or migration across different environments and versions.

Most files are added to the Presto Repository automatically when users register, create or update the corresponding mashables, apps and macros. Presto administrators may also need to manually add files to Presto to provide common thumbnails, for resources used with custom Wires blocks or to register schemas for use in the Wires Mapper block.

Note:

Mashups written in EMML may also use resources such as JavaScript files, Java classes, or other resources. With EMML, however, external resources are accessed through the classpath and cannot be uploaded and managed in Presto.

Common management tasks for files include: Add External Resources as Presto Files, Find Presto Files or Update or Delete Presto Files. See also File Organization for more information on file paths and URLs.

Note:

Custom apps, pluggable libraries and pluggable view libraries typically have several resource files. In most cases, it is better to manage all the resources for custom apps and libraries as a whole to ensure that configuration for the apps and libraries is also correct. .
