Firefox has a similar path, just in the localhost folder instead of #localWithNet. Be aware that the folder after #SharedObjects will be a random string of alphanumerical characters, so it's not going to be the same for everyone. File is still mydata.sol.I've figured out the name and location of the file for two browsers
The file name and location if you used Chrome is
File Name: 00000001.sol
Google Chrome: C:\Users\(Username)\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash\WritableRoot\#SharedObjects\NNFVAMQ5\#localWithNet\##7EF54A21D62AC55B
and the file name and location if you used internet Explorer is
File Name: mydata.sol
Internet Explorer: C:\Users\(Username)\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\X8J3W2W6\#localWithNet\(The name of the folder where the game is stored on your pc)
if you used Firefox, Microsoft Edge, or some other browser than I guess we are out of luck.
