attr 1.4 has been released

DOS's attrib command does not allow you to set the attributes for hidden and system files. Also, it aborts if it encountered an error. So I wrote attr.

You can download the binary here and the source code here.

Here's the changelog:

bump. Someone to

bump.
Someone to answer?
Please, could you just tell me, how to proceed when attr.exe is not in the same directory than the files or folders to treat?

Syntax for attr.exe

Hi,

what must be the syntax, if attr.exe is for instance in C:\Download,
and I want to turn off archive bit for all files in folder D:\TEST ?

or maybe I have to copy first attr.exe in D:\TEST
and then run (from DOS) D:\TEST\>attr -a- -R ?

BTW, in your readme.txt, the 3rd example:
C:\>rem Display what files have their archive bit set on drive C: (but don't change the bit):
C:\>attr -a- -R --dry-run *.*

If I have well understood, it could be also: C:\>attr -a- -R -y ?

Thx in advance.
Charles.
