The Windows implementation of `java.io.File` allows access to NTFS Alternate Data Streams (ADS) by default. Such streams have a structure like “filename:streamname”. A system property `jdk.io.File.enableADS` has been added to control this behavior. To disable ADS support in `java.io.File`, the system property `[jdk.io](http://jdk.io).File.enableADS` should be set to `false` (case ignored). Stricter path checking however prevents the use of special devices such as `NUL:`
