RTFTree's LoadRtfFile method does not release file when it fails.

[yong24s]

To replicate, supply LoadRtfFile() a path to an invalid or corrupted RTF file.

Notice that, File.Move will throw an exception as the file is still being used by RTFTree.

There is no remedy as RTFTree is not an IDisposable.

Code snippet as follows:

RtfTree tree = new RtfTree();
try  #{
       tree.LoadRtfFile(pathToRtfFile);
} catch (System.Exception ex) {
}

File.Move(pathToRtfFile, pathToNewLocation);
