Where are the Jaxx files stored on my desktop? (Can I recover my wallet on my hard drive?)

The data location in which Jaxx stores your wallet information depends on the operating system you are using. As of Jaxx version 1.3 and higher keep in mind that when Jaxx is uninstalled, the wallet data is deleted as well so there will be no way to recover the wallet at that point.
