To configure the allowable file types
1. On the appserver, open each iMIS-related web.config file for editing.
□ iMIS default location: C:\Program Files\ASI\iMIS\net
2. Edit this line to add or remove file types in the value attributes.
<add key="Communities.AllowedUploadFileTypes" value="DOC,PDF,TXT,HTM,HTML,GIF,JPG,PNG,RTF,ZIP,XML" />
3. Refer to the list of the allowable file types that are specified in the web.config file entry.
4. Save the web.config file.
5. Repeat this process for each iMIS appserver that hosts communities where you want to change the allowable file types.

To increase maximum upload file size
If your typical uploaded file size in your Resource Library or blog entries for example are larger than 100 MB, you can increase the maximum file size in web.config files associated with iMIS.
1. On the appserver, open each iMIS-related web.config file for editing.
□ iMIS default location: C:\Program Files\ASI\iMIS\net
2. Locate the <httpRuntime> element and modify the maxRequestLength attribute.
<httpRuntime executionTimeout="3600" maxRequestLength="102400" />
3. Save the web.config file.
4. Repeat this process for each iMIS appserver that hosts communities where you want greater file sizes for attachments.
Tips
The following information can be helpful when managing file types.
■ The MPE file type is sometimes used for MPG Video, but that file type is already in use for Mail Process Engine in iMIS. Rename .mpe files to .mpg in order to upload them to Communities.
■ When a user attaches an XML file to a post and another user downloads it, the default file-opening behavior varies depending on the browser. In Internet Explorer, the XML file may take over the iMIS session, forcing the user to reconnect to the community through another browser window.
Troubleshooting
In order to prevent denial of service attacks, if a user tries to upload a file that is greater in size than the maximum allowed for uploads, the Upload dialog box displays an error. If users report that the Upload dialog box displays an error, check to see if their file exceeds the file size limit.
Be aware that increasing that value could result in a performance penalty on the webserver if the files being uploaded are too large for the server resources available such as available memory and CPU.
