### Version 4.7.0 ### What happened? Hi I'm using Windows 10 to address this issue (https://github.com/SPARQL-Anything/sparql.anything/issues/266#issuecomment-1809971483). Specifically, we are persisting data on a TDB2 and we want to delete the folder once the computation has been completed. However, deleting the folder fails because there are still files used by the program even when the TDB is explicitly closed. I've created a unit test to reproduce the exception. ``` @Test public void playWithTDBLoc() throws IOException { String testFolder = "tmp/testTDB"; Dataset d1 = TDB2Factory.connectDataset(testFolder); Txn.executeWrite(d1, ()->{ RDFDataMgr.read(d1, "https://www.w3.org/1999/02/22-rdf-syntax-ns#";); }); Txn.executeRead(d1, ()->{ RDFDataMgr.write(System.out, d1, Lang.TRIG); }); d1.close(); FileUtils.deleteDirectory(new File(testFolder)); } ``` Am I missing something? Is there anything I can do to explicitly release the resources? ### Relevant output and stacktrace ```shell org.apache.commons.io.IOExceptionList: 1 exceptions: [java.io.IOException: Unable to delete file: tmp\testTDB\Data-0001] at org.apache.commons.io.FileUtils.cleanDirectory(FileUtils.java:345) at org.apache.commons.io.FileUtils.deleteDirectory(FileUtils.java:1206) at io.github.sparqlanything.it.IssuesTest.playWithTDBLoc(IssuesTest.java:643) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) at java.base/java.lang.reflect.Method.invoke(Method.java:580) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:59) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:56) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.BlockJUnit4ClassRunner$1.evaluate(BlockJUnit4ClassRunner.java:100) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:366) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:103) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:63) at org.junit.runners.ParentRunner$4.run(ParentRunner.java:331) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:79) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:329) at org.junit.runners.ParentRunner.access$100(ParentRunner.java:66) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:293) at org.junit.runners.ParentRunner$3.evaluate(ParentRunner.java:306) at org.junit.runners.ParentRunner.run(ParentRunner.java:413) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:69) at com.intellij.rt.junit.IdeaTestRunner$Repeater$1.execute(IdeaTestRunner.java:38) at com.intellij.rt.execution.junit.TestsRepeater.repeat(TestsRepeater.java:11) at com.intellij.rt.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:35) at com.intellij.rt.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:232) at com.intellij.rt.junit.JUnitStarter.main(JUnitStarter.java:55) Caused by: java.io.IOException: Unable to delete file: tmp\testTDB\Data-0001 at org.apache.commons.io.FileUtils.forceDelete(FileUtils.java:1425) at org.apache.commons.io.FileUtils.cleanDirectory(FileUtils.java:338) ... 27 more Caused by: java.nio.file.FileSystemException: tmp\testTDB\Data-0001\GOSP.bpt: Impossibile accedere al file.
