Manages file information.

File validations may be configured defining property bags. The properties are applied to service instances within of a channel that contains it. The properties are:

Property	Description
lumis.portal.file.validation.height	Define the maximum height limit for the file in pixels. This validation will be applied just over files that have this information with metadata.
lumis.portal.file.validation.width	Define the maximum width limit for the file in pixels. This validation will be applied just over files that have this information with metadata.
lumis.portal.file.validation.size	Define the maximum size limit for the file in bytes. This validation will be applied over all files that the File Manager tries to persist.
lumis.portal.file.validation.className	Define a list of custom class validators that will be used by the File Manager when his will try to persist each file. More information check IFileValidator.
