Re-install Ubuntu

I had to do a reinstall of my system and I forgot to back up…can’t beielve I did that. So many things on… This is probably a dumb question but Is there any way to get back the invoices I have created?

You can try and recover the partition. I had to do the a recovery once on ubuntu but can’t remember exactly what link I used. You can try this link [SOLVED] Recover Lost Data from Accidental Partition Deletion
