我有一个外置硬盘,我想在 Mac 和 Windows 上使用。我想避免 ._ 文件问题(请参阅从 Dropbox 中的非 Mac OS 文件系统中删除 ._ 文件)
我可以将 HD 格式化为哪种文件系统,以支持扩展文件属性(从而避免 ._ 文件)并且无需使用额外的驱动程序或任何其他东西即可与 Mac 和 Windows 兼容?
我知道有很多关于 Mac/PC 之间共享的文件系统的问题。我特别想知道哪些文件系统兼容,而且还支持扩展文件属性。
谢谢
答案1
没有什么能满足您的所有标准。macOS 开箱即用且无需执行 ._ AppleDouble 文件的文件系统只有 Apple 专有的 HFS+ 和 APFS 文件系统系列。Windows 开箱即用,无法读取和写入这两个文件系统。
答案2
macOS 操作系统包含该dot_clean
命令,可用于从 FAT32 或 ExFAT 格式的驱动器分区中删除点文件。我认为定期运行此命令所需的工作与清空垃圾箱大致相同。
例如,如果我的外部驱动器名为MYEXTUSB
,那么我可以使用下面显示的命令来删除点文件。
dot_clean /Volumes/MYEXTUSB

DOT_CLEAN(1) BSD General Commands Manual DOT_CLEAN(1)
NAME
dot_clean -- Merge ._* files with corresponding native files.
SYNOPSIS
dot_clean [-fmnsv] [--keep=[mostrecent|dotbar|native]] [dir ...]
DESCRIPTION
For each dir, dot_clean recursively merges all ._* files with their cor-
responding native files according to the rules specified with the given
arguments. By default, if there is an attribute on the native file that
is also present in the ._ file, the most recent attribute will be used.
If no operands are given, a usage message is output. If more than one
directory is given, directories are merged in the order in which they are
specified.
OPTIONS
-f Flat merge. Do not recursively merge all directories in the
given dir. This is off by default.
-h Help. Prints verbose usage message.
-m Always delete dot underbar files.
-n Delete dot underbar file if there is no matching native file.
-s Follow symbolic links. This will follow symbolic dot underbar
files when they are found.
-v Print verbose output.
--keep=mostrecent
The default option. If an attribute is associated with a data
fork, use that. Otherwise, use information stored in the Apple-
Double file. Note that the native fork's data is preferred even
if the data in the AppleDouble file is newer.
--keep=dotbar
Always use information stored in the AppleDouble file, replacing
any extended attributes associated with the native file.
--keep=native
Always use the information associated with the data fork, ignor-
ing any AppleDouble files.
EXAMPLES
The following is how to do an dot_clean merge on the mounted volume test,
always using the dot underbar information.
dot_clean --keep=dotbar /Volumes/test
DIAGNOSTICS
The dot_clean utility exits 0 on success, and >0 if an error occurs.
