Slidefiles Folder
The Slidefiles folder stores all the slide content that is shared over HTTPS. All files are encrypted using AES and a randomly generated key. A new encryption key is used for each content file. The key is stored in the metadata file (set-xxx.exml) for the slide set that includes the slide with the content that will be shared over HTTPs. The names of the files are randomly generated and stored in the same metadata file as the encryption key.
The following table describes file name extensions for the types of slides that the Slidefiles folder contains.
| Extension | Description |
|---|---|
EPNG |
An encrypted PNG image; for example, this can be the larger image in a PowerPoint slide or the slide thumbnail image. |
EPPT |
An encrypted original PPT document. |
EMDI |
An encrypted MDI document – the console converts the Word document into a MDI before it is sent to the Web Conferencing Server. |

The ft folder stores all the handouts (transferred files) that are shared over HTTPS. All files are encrypted using AES and a randomly generated key. A new encryption key is used for each content file. The key is stored in the metadata file (fileset-xxx.exml) created for the transferred file that will be shared over HTTPS. The names of the files are randomly generated and stored in the same metadata file as the encryption key.
