OAR Files are region archives. Please pay close attention as not all of these files are for OpenSimulator, some of these files were created for Aurora-Sim(Current fork named WhiteCore-Sim). If you try to load a WhiteCore-Sim file into OpenSimulator it can cause a bunch of serialization issues! You have been warned.

Disclaimer: I am not resposible for any lost inventory or inventory issues you may have. I am simply providing these files and I do not claim to have much technical knowlege of this proceedure. Although I did test it and it worked fine for me with no problems at all.
