Document MIME Type examples

These settings control the behaviour of documents based on their file extension.

TIP: While these values can be entered manually, it is usually easier to set them automatically by importing an example file. If your computer recognises the file extension, Impact can determine the MIME, Name and Extensions properties as well as the thumbnail images. Press the Import button to use this feature.

The document MIME Type properties are as follows: 

MIME - the identifier by which this type of file is recognised, according to Internet standards.

Name - a descriptive name for this type of file.

Document Type - choose one of your custom types, as defined in the Document Provider Settings

Extensions - enter the file extension(s) to be used to identify this type of file. Do not include the dot/period character. You can include several file extensions, separated by a semi-colon. 

Max File Size - you may set an upper limit on the size of these files or enter zero for unlimited size.

Meta Extractor - choose the method of obtaining meta-data from these files. These methods are determined by the document provider that you are using. 

Thumbnail Generator - choose the method of generating thumbnail images from these files. These methods are determined by the document provider that you are using.

Small / Large / Extra Large - thumbnail images to be used for this MIME Type.

Import - press this button and select any file with the extension you want to configure. The thumbnail images will be determined, plus the MIME identifier, Name and Extensions will be set (but they will not be overwritten, if you had already set them).
