batch-file - 如何获取文件夹中图标文件的文件名以创建/更新文件夹的 desktop.ini？

Question

我需要帮助返回位于文件夹中的文件的文件名。

我已经阅读了几次其他问题，答案似乎是:

for /d %F in (*.*) do echo %~nxF

尽管这似乎对其他人都有效，但当我在批处理文件中运行它时，它有一个异常，并指出此时不应出现“~nxF”。

我要做的是创建一个批处理文件，该文件将读取图标文件名，然后将特定信息输入 desktop.ini最后创建具有相应权限或属性的文件。

@echo off

set NAME=%~dp0
for %%* in (.) do set NAME=%%~n*

set FOLDERICO=%NAME%
set ICONSIZES=16 24 32 48 64 128 256
set FOLDERINI=Desktop.ini

attrib +s "%CD%"

if exist %FOLDERINI% attrib -s -h %FOLDERINI%

echo [.ShellClassInfo] > %FOLDERINI%
echo IconResource=\[Video]\[HD Films]\%FOLDERICO%\Icon\%FOLDERICO%.ico,0 >> %FOLDERINI%

if not "%2"=="" (
    echo FolderType=%2 >> %FOLDERINI%
)
attrib -a +s +h %FOLDERINI%

我认为可以以某种方式改进代码以从根目录而不是特定文件夹运行它。

编辑:更新了我的文件，现在看起来像这样:

@ECHO OFF

attrib +s "%CD%"
set ICODIR=%CD%\Icon\

for %%F in ("%ICODIR%"*.ico) do set ICO=%%~nxF
echo %ICO%

set ICOINI=Desktop.ini
if exist %ICOINI% attrib -s -h %ICOINI%

echo [.ShellClassInfo] > %ICOINI%
echo IconResource=%ICODIR:~2%%ICO%,0 >> %ICOINI%

if not "%2"=="" (
    echo FolderType=%2 >> %ICOINI%
)

attrib -a +s +h %ICOINI%

Pause

我需要将其放入 for 循环扫描根的每个子目录。

这是用于创建或更新的完整注释的批处理代码 desktop.ini 用于文件夹图标，也可选择用于指定文件夹或当前驱动器根目录中的所有文件夹(或删除/注释一行的当前目录)的文件夹类型。

创建 desktop.ini 很简单，看代码就知道了。如果仅使用 Windows 命令处理器的内部命令，更新现有 INI 文件以替换行或在正确的部分添加行要困难得多cmd.exe这不是为此类任务而设计的。

@echo off

rem CreateDesktopIni.bat [FolderName | FolderType] [FolderType]

rem This batch file can be started without any parameter to create or
rem update desktop.ini for all subfolders in root of current drive or
rem current working directory with removing or commenting one line in
rem code below, see comment below label AllFolders.

rem But the batch file can be also started with a folder name
rem to create or update file desktop.ini of this folder only.

rem Optionally it is possible to specify as only parameter a folder type
rem or append as second parameter after folder name the folder type.

rem The folder type can be one of the following strings (not verified):

rem CommonDocuments, Contacts, Documents, Music, MusicAlbum, MusicArtist,
rem MusicIcons, MyDocuments, MyMusic, MyPictures, MyVideos, PhotoAlbum,
rem Pictures, UseLegacyHTT, VideoAlbum, Videos

setlocal EnableExtensions DisableDelayedExpansion
set "FolderType=%~2"

rem Define the subfolder containing the icon for the folder.
set "IconFolder=Icon"

rem Is the batch file called with at least one parameter?
if "%~1" == "" goto AllFolders

rem Yes! It could be a folder name or the folder type.
if not exist "%~1" set "FolderType=%~1" & goto AllFolders

rem First parameter specifies a folder (most likely as not verified).
set "Folder=%~1"
rem Remove trailing backslash if there is one.
rem The batch file should not be called with just \ as folder path.
if "%Folder:~-1%" == "\" set "Folder=%Folder:~0,-1%"

rem Call subroutine to create or update the desktop file for this folder.
call :DesktopINI "%Folder%"
goto EndBatch

:AllFolders
rem Change working directory to root of current drive. Remove or comment
rem the next line to process instead all subfolders in current directory.
cd \
rem Call subroutine to create/update the desktop file for each subfolder.
for /F "eol=| delims=" %%I in ('dir /AD /B 2^>nul') do call :DesktopINI "%%I"
goto EndBatch


rem Subroutine to create or update the desktop file for a folder.

rem This subroutine first searches for the icon file and does nothing
rem if no icon file could be found in the defined subfolder because
rem the subfolder does not exist at all or there is no *.ico file.

rem After determining the icon file (first found *.ico file) with full path
rem including drive letter (remove character d for relative path without
rem drive letter in line with %%~dpnxI), this subroutine checks next for
rem existence of file desktop.ini (case-insensitive) in current folder.

rem desktop.ini with the two or three lines is simply created if this file
rem does not already exist and the user of the batch file has permissions
rem to create this file in the current folder.

rem For an already existing desktop.ini the necessary process to update it
rem is much more complex. All lines outside the section [.ShellClassInfo]
rem must be kept and are therefore just copied to a temporary file, except
rem empty lines ignored by command FOR. Also all lines within the section
rem [.ShellClassInfo] not starting with the string IconFile= or optionally
rem FolderType= (both case-insensitive) must be also simply kept by copying
rem them to the temporary file.

rem An existing line starting with IconFile= in section [.ShellClassInfo]
rem is not copied to temporary file, but instead this line is written to
rem the temporary file with determined icon file name with path.

rem An existing line starting with FolderType= in section [.ShellClassInfo]
rem is also not copied to temporary file, but instead this line is written
rem to the temporary file with folder type as specified on starting batch.

rem If section [.ShellClassInfo] was found and beginning of a new section is
rem detected because of a line starting with an opening square bracket and
rem the line with IconFile= and/or the line with FolderType= was not found
rem in this section during processing the existing desktop.ini, the lines
rem are written next to temporary file to insert them before continuing
rem with the next section.

rem Finally it could happen that section [.ShellClassInfo] is missing in
rem existing desktop.ini and must be therefore added to the file. And it
rem could be that this section exists at end of desktop.ini, but either
rem the line with IconFile= or with FolderType= or both are missing and
rem those lines must be therefore appended to the file.

rem The temporary file is next copied over the existing desktop.ini and
rem then deleted as not further needed. Finally the system and hidden
rem attributes are set on file desktop.ini and the system attribute is
rem set on the current folder as otherwise desktop.ini would be ignored.

建议删除所有以命令 rem 开头的行的注释。以更快地处理批处理文件。

命令行 cd \如果批处理文件应在启动批处理文件时处理当前文件夹的所有子文件夹而不是当前驱动器的子文件夹，则必须删除或注释掉。

目录 选项 /S可以附加到 dir /AD /B在此批处理文件开始时处理当前文件夹或当前驱动器的整个目录树。

环境变量 IconFolder可以仅用 . 定义而不是 Icon在文件夹本身而不是子文件夹中搜索第一个 *.ico 文件 Icon .
