Hi @abirakundu23 ,
For the issue in which an error message is received indicating that the file type is not permitted, this usually indicates that the internal MIME type representation of the file is different than the current file extension for this file. In this case, if the internal file type is known, the file extension should be changed to the proper file type representing that file. If this is not one of the prohibited file extensions, the file should then be able to be uploaded as needed. As in the previous error message, the .zip extension is often included in the allowable file extensions. Thus, compressing the file (which will result in a file with a .zip file extension) and then attaching the compressed file should allow the file to be attached as needed.
If for some reason, this option needs to be disabled, it can be done, by a System Administrator from the Security Properties page on the instance. To do this, perform the following steps:
- Log in to the instance with an account having admin rights to the instance.
- Navigate to: System Properties-> Security.
From the Security properties page that appears, locate the property which has the heading of "This property must be set to activate MIME type checking for uploads (All version Eureka and up). Enables (true) or disables (false) mime type validation for file attachments. File extensions configured via glide.attachment.extensions will be checked for MIME type during upload." This is a boolean property. To de-activate the property ensure the checkbox shows as unchecked (set to a value of No). To recheck the property reset the property (ensure the value shows as checked). After setting the property to the necessary value, click the Save button at the top or bottom of the page. The default setting for this property on an out-of-box instance is No (unchecked).
Note that this adjustment could also be made directly from the sys_properties record for this property. The name of the property is glide.security.file.mime_type.validation. The property is stored in the instance as a true/false property, so the value can be turned on by selecting true and turned off by selecting false.
