Hi all,

I was looking at the Synchronet JavaScript API documentation for the File class:
http://www.synchro.net/docs/jsobjs.html#File
It says the File class has support for binary files and automatic Base64 decoding (among other features). It sounds to me like if I have some Base64-encoded data, I should be able to write that to a file using the File class and it will automatically decode it to binary format. I've tried opening a file with the mode "wb" (write binary) and using the write() method to write the Base64-encoded data. It's not decoding the data to binary though - it's just writing the Base64 string to the file. Might I be missing a step to get it to convert Base64 data to binary?

Basically my flow is this:

var B64Data = "some Base64-encoded data";
var destFile = new File("someFile.bin");
if (destFile.open("wb"))
{
destFile.write(B64Data);
destFile.close();
}

Set destFile.base64=true, other than that, looks right.

Ah, I hadn't noticed that in the docs. Thanks.
