Hi Colas,
thank you for your suggestion. We are currently working in this direction, especially mobile disks and towards FAT32 support. The main problem here are technical limitations which make efficient tracking of files very problematic.
We could easily add support for FAT32 / network shares in a way that would not track files as they are copied or moved. If users are would like this, we could do it. But it has the main disadvantage of copies of the files no longer being tagged and if you move the file to a different location the file would "disappear" from tag2find. Our current goal is to try to support file tracking at a more sophisticated level. If you (the users, not you personally

) tell me you would like to get a "light" version first, we could see how we can fit this into our development plan.
Best regards,
Martin
