Phew! So it looks like you have two copies of the Family Historian Projects folder holding all your projects.

To check they are identical copies, review both File > Project Window lists and check the Last Updated date-time stamps are identical.

There are various strategies for preserving your Projects on OneDrive.

1) Keep your Projects permanently in the One Drive > Documents > Family Historian Projects folder.

Then you don’t have to copy anything. This is what I would recommend.

As soon as FH updates any of your Project files, Media files, etc, they immediately get synchronised with the OneDrive cloud storage.

So there is always a copy on your PC and a copy in the OneDrive cloud.

Further copies can be established on any other PC that synchronises with the same OneDrive account.

If you wish, use the File > Backup/Restore > Full Backup command and save in the This PC > Documents > Family Historian folder as a belt & braces copy.

2) Keep your Projects permanently in the This PC > Documents > Family Historian > Family Historian Projects folder.

a) One option is in File > Project Window, use More Tasks… > Copy Project… and Browse… to the One Drive > Documents > Family Historian Projects folder.

    But you will need to manage each ‘Name of Copy’ as each one must be different.

b) It is easier to use the File > Backup/Restore > Full Backup command and choose the One Drive > Documents > Family Historian Projects folder to hold the backup zip file instead of keeping the backups in your This PC > Documents > Family Historian > Family Historian Projects folder.

    i.e. Change the Tools > Preferences > Backup > Default Backup Folder to be the One Drive > Documents > Family Historian Projects folder.

    There is little benefit in keeping your backups on the same PC drive as your Projects because a PC or disk crash will jeopardise both.

Whichever strategy you adopt, delete any Family Historian Projects folder you no longer need and any others you created in attempting to fix the problem.

Otherwise, sooner or later, you will confuse yourself as to which folder is currently active.

Let me know which strategy you decide to adopt and why.
