So we migrated our jira installation to Windows from Linux one of our projects had a key CON. The attachments connected in this project was stored in attachements/con directory this is not allowed in Windows its a reserved name so a folder like that cant exist. So it created the folder _CON the problem is that we know cant see old attacments or add new ones we get the error: Could not save attachment to storage: Unable to create target directory
Does anyone have any idea i tried to change the project key in Jira but this did not have any effect.
