Whenever I try to create a new folder/directory in IntelliJ IDEA's project structure window, the option doesn't appear in the dropdown when I right-click and go to "New."
See the following image that illustrates the problem:
What could be causing this issue?
Its called Package in intellij. Outside of java (the package
keyword), package, folder, and directory all mean the same thing. A place to hold other packages/folders/directories/ and files in.
Edit: intellij also uses Directory. (it seems by default) Although i'm guessing you were creating a package/folder/directory already somewhere inside of a directory named java. Inside here it will be called Package.
