Currently, if we upload assets - abc.pdf and ABC.PDF - They are treated as different assets in AEM (Your local machine's storage parses it in case insensitive manner) The JCR stores the nodes abc.pdf and ABC.PDF as 2 distinct nodes. Most storage systems even in different OS (Mac | Windows) store files by default in case insensitive manner.
Current/Experienced Behavior:
The assets are treated as different due to their case difference.
Improved/Expected Behavior:
The assets should be treated as similar and versioning popup should be displayed.
Environment Details (AEM version/service pack, any other specifics if applicable):
This has been reported to the engineering under the internal reference ASSETS-32211. The product team will triage this request to verify feasibility based on the prioritization model. This post will be updated according to the Jira request status.
