I use a virtual machine to run Flex and I keep the database in a folder shared with my main system (so I can have it on Dropbox without needing to give Windows access to the internet, which allows me to run it without an antivirus, which allows me to run it fast enough in a virtualized container). Flex can open a project in any folder, I just need to click on the .fwdata file to open it. But FlexTools doen't allow me to do the same. If you can find some time, would you mind changing the program to allow the user to open a database in any random location?
