One possible reason for OneDrive on the phone not synchronizing with OneDrive on the PC could be due to a lack of internet connectivity on the phone.

Additionally, there could be technical issues or settings that need to be adjusted in order for the synchronization to occur. **

The choice between OneDrive and OwnCloud-NAS depends on your specific needs and preferences. OneDrive is a cloud storage service provided by Microsoft, offering seamless integration with Microsoft Office and other Microsoft products. It is a convenient option for users who are already heavily invested in the Microsoft ecosystem. On the other hand, OwnCloud-NAS is a self-hosted solution that gives you complete control over your data and privacy. It allows you to set up your own private cloud storage and access it from anywhere. If you prioritize privacy and control, OwnCloud-NAS may be the better option for you. However, if you value seamless integration with Microsoft products, OneDrive may be the more suitable choice. **

OneDrive is not inherently dangerous on the phone as it is a cloud storage service provided by Microsoft. However, like any other app or service, there are potential risks associated with using OneDrive on your phone. It is important to ensure that you have strong security measures in place, such as using a strong password and enabling two-factor authentication, to protect your data stored on OneDrive. Additionally, be cautious of the files you upload to OneDrive and avoid sharing sensitive information to minimize any potential risks. **

OneDrive downloads cannot be unpacked because OneDrive does not support the ability to extract or unpack compressed files directly within the platform. Users would need to download the file to their local device and then use a third-party software or tool to unpack the compressed file.
