讓這批列出文件名，其路徑為文件 gtr 超過一定大小。如何修改以僅列出沒有路徑和擴展名的文件名？ (Got this batch to list filenames with path for files gtr than some size.. How to modify to list only filenames without path and extension?)

%unit% 和 %dsize% 將在批次到達此點之前定義。可能是這樣的：

set "unit=mb"&set "dsize=100"

現在有沒有辦法只列出文件名？如果可能的話，誰能告訴我這是如何工作的？我不明白“set size=%1”和“echo.%~2”部分。“%~2”如何回顯帶路徑的文件名？

for /r %%m in (%ext%) do call :logic %%~zm "%%m"
exit
:logic
set size=%1
if '%unit%'=='bb' set "sizen=%size%"
if '%unit%'=='kb' set "sizen=%size:~0,‑3%"
if '%unit%'=='mb' set "sizen=%size:~0,‑6%"
if not defined sizen set sizen=0
if %sizen% gtr %dsize% echo.%~2>> temp.txt&cls
exit /b

方法 1:

for /r %%i in (*.*) do (
echo %%~xxx )

Here is your options (to replace my xxx in example)

%~I         ‑ expands %I removing any surrounding quotes (")
%~fI        ‑ expands %I to a fully qualified path name
%~dI        ‑ expands %I to a drive letter only
%~pI        ‑ expands %I to a path only
%~nI        ‑ expands %I to a file name only
%~xI        ‑ expands %I to a file extension only
%~sI        ‑ expanded path contains short names only
%~aI        ‑ expands %I to file attributes of file
%~tI        ‑ expands %I to date/time of file
%~zI        ‑ expands %I to size of file
%~$PATH:I   ‑ searches the directories listed in the PATH
               environment variable and expands %I to the
               fully qualified name of the first one found.
               If the environment variable name is not
               defined or the file is not found by the
               search, then this modifier expands to the
               empty string

The modifiers can be combined to get compound results:

%~dpI       ‑ expands %I to a drive letter and path only
%~nxI       ‑ expands %I to a file name and extension only
%~fsI       ‑ expands %I to a full path name with short names only
%~dp$PATH:I ‑ searches the directories listed in the PATH
               environment variable for %I and expands to the
               drive letter and path of the first one found.
%~ftzaI     ‑ expands %I to a DIR like output line

In the above examples %I and PATH can be replaced by other valid values. The %~ syntax is terminated by a valid FOR variable name. Picking upper case variable names like %I makes it more readable and avoids confusion with the modifiers, which are not case sensitive.
