Are you by any chance, separately, removing files from your index
directory manually? That's the one case I know of which can lead to
that exception, if you also have an IndexReader open on the directory
at that time.
The code below has one problem. In your if statement true & false
clauses, you declare "IndexWriter writer = ...", but, this means you
cannot use the "writer" variable outside of those scopes. So I don't
see how that code can work.

Hi,
I am using Lucene to index text based files :
File file = new File("C:/index");
if(file.exists() == false{
IndexWriter writer = new IndexWriter(file,new
StandardAnalyzer(),true);
}
else
{
IndexWriter writer = new IndexWriter(file,new
StandardAnalyzer(),false);
}
FileReader fr = new FileReader("C:/source");
BufferedReader br = new BufferedReader (fr);
String records = br.readline();
while (records != null)
{
Document doc = new Document();
doc.add(new Field("indexRecords",
indexRecords,Field.Store.NO, Field.Index.TOKENIZED));
doc.add(new Field("storeRecords",
storeRecords,Field.Store.YES, Field.Index.NO));
writer.addDocument(doc);
records = br.readLine();
if(records == null)
{
writer.close();
}
}
it throws the following error
java.io.IOException: Cannot overwrite: C:/index/_r.fdt

Can you describe how you are using Lucene, and provide a full
