The last character in a folder name can't be replaced
directory, formatting, java, rename
Solution
You are getting this exception because you have a space as the last character in your file name and underlying OS (Windows) will not accept a file name with a trailing space character.
This space as a trailing character is most likely result of multiple `String#replace` calls, make sure you don't replace very last char in the String with space.
Problem
I use .replace() instructions in order to clean up folder names. This worked fine for these characters so far: {".", " ", "(", "["} but as soon as I got to the closing brackets, I receive an error. When I look at the folder which threw this error it always has a closing bracket at the end. Upon manually removing the closing bracket and executing the code again, an error occurs at the next folder with a trailing bracket. In every case the characters are being replaced with a single space. ``` public void cleanFormat() { for (int i = 0; i < directories.size(); i++) { File currentDirectory = directories.get(i); for (File currentFile : currentDirectory.listFiles()) { String formattedName = currentFile.getName(); formattedName = formattedName.replace(".", " "); formattedName = formattedName.replace("(", " "); formattedName = formattedName.replace(")", " "); // error here formattedName = formattedName.replace("[", " "); formattedName = formattedName.replace("]", " "); // and here formattedName = formattedName.replace(" ", " "); Path source = currentFile.toPath(); try { Files.move(source, source.resolveSibling(formattedName)); } catch (IOException e) { e.printStackTrace(); } } } JOptionPane.showMessageDialog(null, "All folders have been formatted"); } ``` Error being: ``` Exception in thread "AWT-EventQueue-0" java.nio.file.InvalidPathException: Trailing char < > at index 68: A Good Old Fashioned Orgy 2011 LIMITED 720p BluRay X264-AMIABLE EtHD at sun.nio.fs.WindowsPathParser.normalize(Unknown Source) at sun.nio.fs.WindowsPathParser.parse(Unknown Source) at sun.nio.fs.WindowsPathParser.parse(Unknown Source) at sun.nio.fs.WindowsPath.parse(Unknown Source) at sun.nio.fs.WindowsFileSystem.getPath(Unknown Source) at sun.nio.fs.AbstractPath.resolveSibling(Unknown Source) at domain.DirectoryListing.cleanFormat(DirectoryListing.java:86) ``` Name of folder: ``` A Good Old Fashioned Orgy 2011 LIMITED 720p BluRay X264-AMIABLE EtHD] ```
