    AAX to MP3

    AAX to MP3

    Audible AAX to MP3 Converter

    Usage: - Install the Audible Manager and open a file of your account. - Sign in into your audible account (in the application). Now the program can convert your audible files. - Start Aax2Mp3 (AaxToMp3GUI.exe) and select the file you want to convert. - Click the Convert button. - The buttons are grayed out and it shows how far the conversion has progressed. - - The time should always continue to increase. - If the buttons are clickable again, the conversion is completed. The mp3 file is now to be found in the same folder as the AAX file. The conversion need (depending on the computing power) for 1 minute of audio approximately 2 seconds. The conversion of Aax to MP3 is fast, free, and requires no I-Tunes. Have fun while listening! If you want to help developing this software, please contact me. I do not have enough time to develop alone.

    This plugin mimics the "open selected file" in PSPad. I am a PHP developer and i often see an 'require_once("../this/is/some/file.php");'. In pspad you can select the whole path (../this/is/some/file.php) and open it from the menu. Now you can do the same in notepad++. Just select the whole path and press alt+o, or use the button in the toolbar on top. It will open the file automatically. The plugin understands the relative path. The code is also available on https://bitbucket.org/sgezel/quickopenplugin

    CrapFixer

    CrapFixer

    Fixes the crap Windows leaves behind

    CrapFixer is a lightweight Windows cleanup and tweaking toolbox aimed at removing or reducing the everyday “junk” Windows accumulates, while keeping changes understandable and reversible. It’s positioned as a fast, no-fluff utility that focuses on practical fixes rather than turning into an overstuffed “optimizer” suite. The workflow is deliberately simple: you analyze your system, review what’s flagged, and then apply recommended changes with a single action. It distinguishes between items that are recommended to fix and items that are already optimized, helping you avoid unnecessary changes. The project emphasizes safety by making most tweaks undoable, and it supports running with administrator privileges when deeper changes (like certain registry locations) are required. For users who want more clarity, it includes a help lookup per tweak and offers log review so you can understand what happened and share results for troubleshooting.
