Exclude file type in DAM

[lydie_soler]

Hello,

For security reasons, we don't want to let an author upload some file types (.exe, .js for example)

How can we do that in AEM ?

Thansk a lot

Adobe hotfix (71519) resolves the issue. You can configure the specified MIME type you want to allow in felix console.

I don't know whether there is any OOTB configuration to limit the file types. But there is a community article for restricting the upload based on size of the file - http://experience-aem.blogspot.com/2014/12/aem-6-sp1-classic-ui-restrict-large-or-small-files-upload.... You can customize it and add your logic of checking the file types. You can either just check the file extensions in the javascript or invoke a backend servlet to check the file headers for the mime types. Also, this is limited to Classic UI only.

YOu can write a DAM handler and have control over the file type.  WHen writing a DAM handler - you use this API: 

https://docs.adobe.com/docs/en/cq/5-6-1/javadoc/com/day/cq/dam/commons/handler/AbstractAssetHandler....

See:

Using a DAM handler - you can get mime type.

Hello,

I have the same request, but I don't find how to use your trick.

I need to help AEM skipping the upload of "Thumbs.db" files which are killing my webdav mount when AEM try to store it.

Many thanks
