Testing if it is a file or folder?

[Squashman]

I have seen this question asked several times. And Dave even updated his post on SO last month.

How did none of us ever see this?

Use %~a1 to display the Extended Attributes of a file.
FOR's %%~aI recognizes 9 NTFS file attributes. The expansion of a file attribute produces a series of 9 dashes, with each recognized attribute replacing a dash with a letter. A file with no recognized attributes or with none set will expand to 9 dashes like this: ---------

Attribute Expansion
FILE_ATTRIBUTE_DIRECTORY d--------
FILE_ATTRIBUTE_READONLY -r-------
FILE_ATTRIBUTE_ARCHIVE --a------
FILE_ATTRIBUTE_HIDDEN ---h-----
FILE_ATTRIBUTE_SYSTEM ----s----
FILE_ATTRIBUTE_COMPRESSED -----c---
FILE_ATTRIBUTE_OFFLINE ------o--
FILE_ATTRIBUTE_TEMPORARY -------t-
FILE_ATTRIBUTE_REPARSE_POINT --------l
FILE_ATTRIBUTE_NORMAL ---------

I knew and used it, and i'm sure i wasn't the only one, although i didn't read it on ss64; for example see:
- http://www.dostips.com/forum/viewtopic.php?p=28311#p28311 just search for "%%~at"
- http://www.dostips.com/forum/viewtopic.php?p=27548#p27548 just search for "arg=%%~ac"

I only missed, that you were looking for something like that.

Edit: I'm not sure but I think, i've seen such a table somewhere within the MS C++ documentation, but i can't find it (the names used above are defined in "win32.h").

You would think the "a" parameter would be documented in the help for CMD.exe or the FOR command. I can't find it documented in any of the help.

Here is an archived snapshot from Sept 10th, 2013

There once was a time when the expansion was described on ss64 as simply:
%~a1 Display the file attributes of %1

Here's an example from a now little used newsgroup.

will this if exist %1\ work on FAT32 (I have a memory that it will not , but I'm not sure)?
Also file attributes on ss64 are pointed as NTFS file attributes.

Here a small batch file:

Code: Select all

@echo off
setlocal
:: echo %1   %~a1
set test=%~a1
set test=%test:~0,1%

if %test%==d (echo %1   is a directory) else echo %1   is not a directory

Tested in Win7.

Here some examples:

Code: Select all

D:\CMDVerz>exattr InRegEx5.bat
InRegEx5.bat   is not a directory

D:\CMDVerz>exattr UniCode
UniCode   is a directory

D:\CMDVerz>exattr "findstr info.txt"
"findstr info.txt"   is not a directory
