What is an OLK15FOLDER file
OLK15FOLDER files mostly belong to Microsoft Outlook. An .OLK15FOLDER file is a container used by Microsoft Outlook to store email messages, calendar events, contacts, tasks, and other items associated with a specific folder within an Outlook profile. It functions as an index, pointing to individual .OLK15MESSAGE files that contain the actual content of each item within the folder. The .OLK15FOLDER file itself doesn't hold the email content but rather metadata about the folder and the items it contains, such as sender, recipient, subject, date, and pointers to the corresponding .OLK15MESSAGE files. This structure allows Outlook to efficiently manage and access large volumes of data within a user's mailbox. The "15" in the extension likely refers to the version of Outlook or the underlying data storage technology associated with these files, specifically Outlook 2013 and later versions.
