That's a true story:

One of our client were using one of Turkey's biggest accounting software. That software were creating folders with company names. Sample you create a company "Mycomp", it were creating all of data files under mycomp folder.
Our client's name was acem and their accounttant was created "acem" company. And he decided create a second company for them named "acem.". That accounting software decided as "acem." a different company name and accepted it and created all files overwrite olds. You know acem and acem. are same folders actually. When we called them they just said us "Yes, it's a bug. We will fix it at next release.". I don't know how at Australia but at Turkey at least %50 of small clients don't make backup. So... :)
