How can we restrict DAM from uploading assets without an extension

Avatar

There seems to be bug in our project where in I am unable to delete an asset which was loaded without an extension.

I tried to delete and we get a console error.

How can we restrict uploading assets without an extension to DAM? Do we have anything OOB for this fundtionality?

Hi @P_V_Nair ,

 

There is no direct OOTB way of restricting upload of assets without an extension, but you could achieve this with few configurations/customisations as below:

 

1.  AEM by default identifies the mime type of an asset using its extension. For assets without an extension, there will not be any mime type detected. So, to restrict upload of these kind of assets that don't have a detected mime type, Disable the "Allow All Mime" Flag of DAY CQ Asset Upload Restriction configuration. But, while doing so, please make sure that you are adding all the expected different Mime types in the "Allowed Asset MIMEs" field.

2. Customise the DAM Update Asset Workflow with an additional process step that checks for extension less assets and deletes them.

 

Hope this helps.

Thanks!

@P_V_Nair Write a filter to validate the file before it gets uploaded in DAM. Refer a sample filter below :
