Multiple encrypted containers of the same data, is it a risk for forcing decry

[imagenesis]

Does having multiple encrypted contrainers of the same data present an oppurtunity to analyze the external container and get access to the contents?

For example, I have an encrypted flash drive, a 7 gb encrypted container on an external harddrive and a 100gb container on my main hard drive. There are a few folders with a lot of small files that are the same in all three containers. Would this enable a state of the art attacker to gain access to any of the containers?

If they knew the contents of the folders, it would help. Otherwise, if you have one copy of a encrypted file/folder or 1000 copies, the effort required would be the same.
