Windows file attributes / version of file - windows

I know for dll files you can read an Assembly version, but I was wondering if there's some way to mark or read versions from ANY filetype (jpg for example). I'm making an update program that only updates what's necessary and it'd be better if all files were versioned instead of keeping track of versions in a separate file.
Oh and this is intended for winXP but if I there is a win7/windup solution that'd be awesome.

The version of an assembly is something that is specific to the assembly file format. A general "file" (such as a JPEG file) is just a bag of bits and the Windows filesystem doesn't have any "version" metadata associated with such a file.
One approach to solve your problem might be to compute a hash (such as using SHA1) over the content of the file. If you have two files and the SHA1 hashes match, then you can be pretty darn sure that the complete contents also match. (You can't be that sure with an embedded file version.)

is there a way to tag video files independent of any tool

We are in the 21st century and still there is no good way to tag photos and videos? There is always a dependency on some tool... Is there no way to make the file autonomous with respect to its tags?
Video files, for example, are not friendly to tags. some video formats do not allow tagging at all. Some tools keep the meta data in their own external representation and when you copy the original file to some new destination, the meta data of the file in the destination is lost. Also this metadata may only be seen by this proprietary tool and is not seen by other tools (e.g. tagging by Adobe products are not visible/searchable in Windows Explorer)
Is there a universal way to tag any file including video files so that
searching for files having a certain tag is possible in any tool
when a file is copied, the tags are transferred with it
when the file is edited in any tool and re-saved, the tags are not lost...?
There are no universal ways at this point, if there ever will be one.
Probaby the closest we got is file tagging provided by popular OSes based on a certain file systems' feature called 'forking'. By this means Windows and Mac provide an ability to easily add meta data (including keywords) to any file on the file system, without changing the file's content. One serious drawback of this feature is that it does not cross file-system's boundary, i.e. if you simply upload a file to the web, or copy it to a different type filesystem - the metadata will be lost. There are ways to copy such metadata but that requires consideration and use of appropriate tools.

Store file version in non-exe file

I often have the need to store a certain file version in a non-exe file, just the way I give a file version to an .exe, for example "1.0.392"
However, I have not found a way to do that for non-exe-files (such as .db files, etc.)
Is there are way to do that in a simple way?
Thank you!

Diffing Windows .exe/.dll files

Since we're storing some .dlls and some .exes in version control (don't ask...), I'd like to be able to reliably diff which files have changed between revisions. Basically, bindiff seems to be what I am looking for (see tools for diffing windows binaries? and Deterministic builds under Windows), but the only download link I could find was for Windows XP (actually given in the second link).
Is bindiff available for Windows 7? Or is there a similar tool that can exclude PE timestamps and whatever else is in there that changes between compilations of the same files?
Our tool (ECMerge) has a specific Executable File Format for that, it declares a field "PE Header Timestamp" which can be ignored in comparison options. If it is not enough in your case, it is possible to increase the capabilities of the file format through scripting (in JavaScript).

Visual Studio: different ocx file version number for new OS?

I'm looking for general advice. I created a Visual Studio 2010 project that outputs an ocx file that is used on XP and Vista machines. The DLL on which it depends has been updated on our Win7 machines. I simply needed to rebuild for Win7 using the exact same code with an updated .lib file. I created a second project configuration (ReleaseW7) and it only differs from the original project config (Release) in that it points to the new .lib.
So now I have 2 files both named xx.ocx. Besides looking at the name of the folder each file resides in (or looking at the creation time of each) there is no way to determine which is which. I thought of using different file version numbers but as far as I can tell (and I'm relatively new to this so I could certainly be wrong) that would require two separate projects each with a slightly modified resource (.rc) file, instead of simply having two configurations within the same project. If nothing more, that seems like a waste of hard drive space. It also feels like the "wrong" way of using file version numbers
Is there a cleaner or more "standard" way of handling this? All I really want is a way for the folks who install the ocx and support the end user to know for certain that they are working with the correct file.
Long story short, I decided to use different version numbers. I was able to setup a preprocessor definition for the resource compiler and use that to handle different versions of VS_VERSION_INFO in my .rc file.
In case anyone is interested, this is the resource I found:

Can VS_VERSION_INFO be added to non-exe files?

My windows co-workers were asking me if I could modify my non-windows binary files such that when their "Properties" are examined under Windows, they could see a "Version" tab like that which would show for a Visual Studio compiled exe.
Specifically, I have some gzipped binary files and was wondering if I could modify them to satisfy this demand. If there's a better way, that would be fine, too.
Is there a way I could make my binaries appear to be exe files?
I tried simply appending the VS_VERSION_INFO block from notepad.exe to the end of one of my binaries in the hope that Windows scans for the block, but it didn't work.
I tried editing the other information regarding Author, Subject, Revision, etc. That doesn't modify the file, it just creates another data fork(what's the windows term?) for the file in NTFS.
It is not supported by windows, since each file type has their own file format. But that doesn't mean you can't accomplish it. The resources stored inside dlls and exes are part of the file format.
Display to the user:
If you wanted this information to be displayed to the user, this would probably be best accomplished with using a property page shell extension. You would create a similar looking page, but it wouldn't be using the exact same page. There is a really good multi part tutorial on shell extensions, including property pages starting with that link.
Where to actually store the resource:
Instead of appending a block to the file, you could store the resource into a separate alternate data stream on the same file. This would leave the original file stream non corrupted on disk and not cause its primary file size to change.
Alternate data streams allow more than one data stream to be associated with a filename. Each stream is identified by a colon : at the end of the filename and an identifier.
You can create them for example by doing:
notepad test.txt:adsname1
notepad test.txt:adsname2
notepad test.txt
Getting the normal Win32 APIs working:
If you wanted the normal API to work, you'd have to intercept the Win32 APIs: LoadLibraryEx, FindResource, LoadResource and LockResource. This is probably not worth the trouble though since you are already creating your own property page.
Can't think of any way to do this short of a shell extension. The approach I've taken in the past is a separate "census" program that knows how to read version information from any kind of file.
Zip files can be converted into exe files by using a program that turns a zip file into a self-extracting zip (I know that WinZip does this, there are most likely free utilities for this also; here's one that came up on a search but I haven't actually tried it). Once you've got an exe, you should be able to use a tool like Resource Hacker to change the version information.
It won't work. Either Windows would have to know every file format or no file format would be disturbed if version information were appended to it.
No, resource section is only expected inside PE (portable executable; exe, dll, sys).
It is more then just putting the data inside the file, you have a table that points to the data in the file header.
What you can do if you have NTFS drive, is to use NTFS stream to store custom properties this way the contact of the binary file will remain the same, but you will need to use a custom shell extension to show the content of the stream.
