# DuplicateFilesAndFolders

_DuplicateFilesAndFolders_ is an open-source tool to find and (optionally) delete duplicate files and folders, written in Java.

It identifies duplicate files and folders by calculating and comparing file hashes (something that Git does, too). For easy operation, _DuplicateFilesAndFolders_ provides an Eclipse SWT/JFace-based graphical user interface.

I developed _DuplicateFilesAndFolders_ on Windows 7 (64-bit), but it should be easy to port it to other platforms.

Enjoy &mdash; Lorenz

## Build Instructions

### Prerequisites

* You are running a Windows (64-bit) system.
* You have installed Java SDK 7 (64-bit) or higher  on your system (I used Java SDK 8 (64-bit)).
* You have installed an Eclipse IDE on your system (I used Eclipse 4.5.0 &ldquo;Mars&rdquo; (64-bit)).

### Instructions

1. Download this project&rsquo;s ZIP file from GitHub.
2. Unzip it to a temporary folder.
3. Import the `DuplicateFilesAndFolders` project from the temporary folder into your Eclipse IDE as an import source _General > Existing Projects into Workspace_.
4. In the _Project Explorer_ view, right-click _DuplicateFilesAndFolders_ and select _Run As > Java Application_.
5. The _DuplicateFilesAndFolders_ application starts.
6. If you like to create a `DuplicateFilesAndFolders.jar` JAR file, continue:
7. Close the _DuplicateFilesAndFolders_ application.
8. In the _Project Explorer_ view, right-click _DuplicateFileAndFolders_ and select _Export..._.
9. Select _Java > Runnable JAR file_.
10. Click _Next >_.
11. Under _Launch Configuration_, select _DuplicateFilesAndFolders - DuplicateFilesAndFolders_.
12. Under _Export destination_, enter the full pathname of the exported application, for example `C:\TEMP\DuplicateFilesAndFolders.jar`.
13. Select the radio button _Package required libraries into generated JAR_.
14. Click _Finish_.
15. Use a file explorer to find the exported JAR file `DuplicateFilesAndFolders.jar`.

## Porting Tips

To port _DuplicateFilesAndFolders_ to another platform, apply the following changes:

1. Adjust in method `Utils.getInitialFolderToScanPath()` the string that is shown as the initial folder path.
2. Adjust in method `Utils.getExplorerCommandLine()` the command-line string that launches the file explorer, opening a specific folder.
3. Replace the SWT library `org.eclipse.swt.win32.win32.x86_64_XXX.jar` with the SWT library specific to your platform. (The library name follows the pattern `org.eclipse.swt.<platform>_<version>.v<timestamp>.jar`.)
