Filename without Extension in Batch Script

for %%a in (.\*.jpg) do

The code above will store every jpg picture's name in %%a, but it stores the full name with the file extension, for example "Q.jpg".

I'm using a cmd utility for resizing images,

resize /width:100 %%a %%a.jpg

It will resize "Q.jpg" and then name it to "Q.jpg.jpg", as you can see the extension is now a part of file name!!!

I want to avoid it.

Simple, type for /? for more info:

To only get filename:

for %%a in (.\*.jpg) do resize /width:100 %%a %%~na.jpg

Quoting Windows batch help (type for /?):

%~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

And that should help you with any further problems.
