Tags are stored inside Filezo 's data files. Since tags are not stored inside tagged Windows files, the tags will not get synced with OneDrive etc.
However, you can access the shared tagged files and folders on any other PC where Filezo is installed.
Just install OneDrive (or similar) on your Windows PC so that it creates a virtual drive on your system. Now tag files/folders on this virtual drive using Filezo . On the other PC, do the same and install Filezo . All your tags and information about tagged files/folders will be restored back.
Tags in Filezo are saved as part of NTFS file system. So if you simply copy files/folders from one NTFS drive to another NTFS drive directly then all the tags will be retained. After copying, just install Filezo and it will restore all the tags back even if you have copied on another drive on inside another folder.
If you have your tagged files on a file system such as FAT32 also, you can simply copy everything as it is to another computer. Filezo will restore all the tags back. On Non-NTFS file syste, Filezo stores the tags differently. But they are still restorable.
