This directory contains tests for the java.io package. Some important things to note: -- The file dataoutput-jdk.out is the results of the DataInputOutputTest test run through the JDK. It is needed for the real test so please don't delete it. -- The directory filetest and its contents are used for the FileTest test. If that test bombs in the middle, it may leave the directory renamed to something else. In that case, you will need to rename it back manually to re-run the test after making fixes.
