I can't find my bin folder. Where is it located?

The other day I was trying to download something for Minecraft and it involved my bin folder. So I was looking for it and couldn't find it. I then thought that I might have accidentally deleted it, but didn't find it in the trash. I have no idea how to get the bin folder back with all the Minecraft binary files in them.

Pre 1.6 (Old Launcher)

If you deleted your bin directory it will be recreated when you launch the Minecraft client.

If the client starts up, your bin directory is almost certainly at:

• Windows: C:\Users\You\AppData\Roaming\.minecraft or %AppData%\.minecraft
• Linux: ~/.minecraft
• Mac: ~/Library/Application Support/minecraft

Post 1.6.1 (New Launcher)

The new launcher does not create a bin directory. Instead, there is one folder for every installed different version of the game, located in the folder versions in your Minecraft directory (see above). For example 1.7.10, or 14w30c. Note that multiple profiles can use the same version and there will only be one folder.
