实现虚拟文件系统时可以安全忽略的各种系统文件的列表

Question

我正在开发一个WebDAV服务器，它从虚拟文件系统中的数据库中提供信息。

因此，用户可以在服务器上创建文件，并在数据库中自动创建它们。

现在，只要用户连接到服务器，某些操作系统就会立即创建自己的元数据文件/文件夹（考虑Thumbs.db，desktop.ini，.fseventsd，DS_Store，...）

这个文件使数据库变得混乱 - 并且往往也会降低性能（OSX例如在打开文件夹后会立即执行大量索引，这意味着对数据库的点击次数很多）

因此，为了表现和清洁，我正在寻找由各种操作系统创建的（元）文件/文件夹的“完整”列表 - 服务器可以“安全”这些文件/文件夹。

到目前为止我的清单：

//TODO: get rid of system files
/*
 *** everywhere
 * Thumbs.db
 * desktop.ini
 * .DS_Store
 * .desktop
 * AlbumArt*.jpg
 * Folder.jpg
 * ._[ParentFoldername]   // e.g. /foo/bar/._bar
 * ._[ExistingFoldername] // e.g. /foo/._bar
 * ._[ExistingFilename]   // e.g. /foo/bar/._baz (baz is a legit file inside bar)
 * ._.                    // ?!? 
 *** root only
 * System Volume Information
 * .fseventsd
 * $recycling.bin
 * $Recycle.Bin
 * Recycled
 * .Trashes
 * hiberfil.sys
 * pagefile.sys
 * .hidden
 * mach_kernel
 * Backups.backupdb
 * Contents
 *
 *** special
 * .metadata_never_index // fake this file in root
 *                       // (should keep OSX from indexing)
 */

我现有的OSX测试结构是：

/MarioDemo/
/FrankTest/
/TestItemRelation/

/.metadata_never_index

/MarioDemo/Alphabetical/
/MarioDemo/Hierarchical/

此处打开/ MarioDemo /：

我猜你的清单已经很完整了。除非您特别想要过滤掉特定的文件类型，否则我只会添加以下内容：

.DS_Store?
._*
.Spotlight-V100
.DocumentRevisions-V100
.fseventsd
.MobileBackups
Icon?
__MACOSX
ehthumbs.db
desktop.ini
*.desktop
*.bak
.*~
*~

我从名为Ignoramus的项目中获取了这些内容。带有模式的相关文件是here，采用emacs格式。完全匹配的列表打印在下面，这是我从以下地方获取的：
