VLC：如何删除磁盘上的文件

我从 Youtube 下载视频以便稍后观看。我使用 VLC 观看视频，看完视频后，我想直接从 VLC 中删除磁盘上的文件。

我找到了几个关于如何实现这一点的指南，但没有一个适合我：

https://forum.videolan.org/viewtopic.php?f=29&t=108811 https://forum.videolan.org/viewtopic.php?f=29&t=113813 http://addons.videolan.org/CONTENT/content-files/153041-Diskdelete.lua

如果我按照这些操作，什么也不会发生：没有按钮，而且如果有键盘快捷键，我也没有被告知。

那么如何在 VLC 中获取按钮/键盘快捷键来从磁盘中删除当前正在播放的视频文件？

我在 GNU/Linux Mint 上使用 VLC 2.0.8。

答案1

因此将文件放入 ~/.local/share/vlc/lua/extensions。我将其命名为 DeleteFile.lua。

启动 VLC 时，您会看到一个新菜单项：查看 > 检测文件。这是我遗漏的最后一步。

代码运行得不太好。我修改了它：

https://gitlab.com/ole.tange/tangetools/-/blob/master/wastebasket/dotlocal/share/vlc/lua/extensions/WasteBasket.lua

.waste它现在在文件目录和任何（祖父*）父目录中搜索名为 的目录，并将文件移动到那里。因此，您需要创建一个名为 的目录.waste。

当您启动 VLC 时，您会看到一个新菜单项：查看 > 将当前播放的文件移至废纸篓。

INSTALLATION (create directories if they donot exist):
- put the file in the VLC subdir /lua/extensions, by default:
* Windows (all users): %ProgramFiles%\VideoLAN\VLC\lua\extensions\
* Windows (current user): %APPDATA%\VLC\lua\extensions\
* Linux (all users): /usr/share/vlc/lua/extensions/
* Linux (current user): ~/.local/share/vlc/lua/extensions/
* Mac OS X (all users): /Applications/VLC.app/Contents/MacOS/share/lua/extensions/
- Restart VLC.
- The extension can then be found in the menu:
    View > Move current playing file into wastebasket

答案3

这些都不适合我所以我修改为：https://gist.github.com/e-desouza/9c340a5373492befb1203428e458bbf5。请注意，这仅适用于 OSX，删除前没有任何警告等。要使其成为快捷方式：

OSX 系统偏好设置->键盘->应用程序快捷方式 > +（单击加号按钮并选择 VLC 应用程序）

菜单标题为“VLC Delete OSX”（减去引号）并使用所需的快捷方式。（在我的情况下，我选择 Ctrl+D）
