4.7.4.1.1.2 Preview

The preview function allows users to quickly view a document to assess whether or not it corresponds with the document they are searching. Preview is a useful tool and can be used when an individual is searching for a file that the user does not recognize by name.

*The preview functionality is dependent on file size and complexity. This means that the more complex and large a file is, the longer the preview will take to generate. For complex files, it is recommended that users simply download.

*The default File Size cap for conversion to Preview a file is 10MB. We recommend leaving it as is to reduce delays but System Admin can edit under the Advanced tab by selecting the FILE_PREVIEW_MAX_FILE_SIZE setting

*The delay to generate preview for new files is 60,000 miliseconds (1 minute). System Admin can edit it under the Advanced tab by selecting the FILE_PREVIEW_TIMER_DEFAULT setting
