I'm trying to make a simple batch for windows that will basically sync two folders, the catch is that the files in the folders can be named arbitrarily and the snyc should be based on the checksum. I've only found information about xcopy that compares the timestamp so I'm wondering if this is possible in a simple matter at all.
Here is the scenario I'm trying to manage, you've got the "Import Folder" containing the files named A_2.bmp and A_3.bmp and the "Target Folder" containing file A_1.bmp.
File A_2.bmp is infact the same file as A_1.bmp, just with a different name and thus should be skipped, A_3.bmp should then be copied over to target folder and icrementally renamed to A_2.bmp.
This probably sounds more like a work for patching software, but I'm looking for a solution that doesn't require building patches all the time and is open for the user (so he can just drop files into the import folder and run it whenever the need arises)
If there is software for such a thing that is free and can be distributed without installing I would also consider this a good option, but I haven't found anything.
I'm thankful for any advice and help on this matter so thank you very much for your time and help!
You have this command line utility :

You can then make a bat who simply test the checksum of the files

MSI database contains set of tables, and I can successfully enumerate File table, which has all deployable file' meta-deta. What I need to extract is the actual contents of those files. msiexec, lessmsi, 7-zip all can do it, but I couldn't find any source/API to do it.
What I've discovered it that all other (resource) files are in Binary table, and Data field can be used to get content of those files (like icons, custom DLL etc).
Further, I found and know that Media table contains information about the .CAB file (MSI has all content embedded with <MediaTemplate EmbedCab="yes"/>. This simply means the CAB file contains the actual content. I probably need to read contents from "Structured Storage" of the .msi file.
How to extract the contents of CAB/MSI file, using native C Msi* functions?
Phil has given you the easy/simple answer but I thought I might give you a little more information since you've done some research. Checkout:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa372919(v=vs.85).aspx
This is where the structured storage is. You'll see something like Disk1.cab as the Name (PK) and binary data. The data is a CAB file with the file entry in the cab matching the File.File column. From there you can use the File.FileName column to get the short name and long name (you'll want the long name no doubt) and do a joint to the Component table to get the directory table ID.
You'll also need to recurse the directory table to build the tree of directories and know where to put the files.
Fun stuff. There's some libraries in C# that make this WAY simpler. Or just call msiexec /a as Phil says. :)
The most straightforward to extract all the files to some location is to install the product in "advertised" mode. If you do a:
msiexec /a [path to msi] TARGETDIR=[some folder]
you'll see what happens.
In C++ call MsiInstallProduct () with that command line.
You have gotten many good answers already, including the use of dark.exe from the WiX toolkit. By downloading the WiX source code you should be able to get the code you need ready-made from there. I assume you may already have done this.
Chris has already linked to the DTF code you can check, but here is a link directly to dark.exe as well: https://github.com/wixtoolset/wix3/tree/develop/src/tools/dark. I would try both. This is C#, you seem to want native.
UPDATE: Before I get to the Win32 features you can use, check out this little summary of the C# DTF features: How to programmatically read the properties inside an MSI file?
Native Win32 functions: The database functions to deal with an MSI file can be found on MSDN (this is to deal with the MSI file as a database). There are also MSI Installer Functions (used to deal with the MSI file as an actual installer).
You can certainly find good examples of native code for this with a good Google search. Have fun!
BTW: It would help with a description of the actual problem you are trying to solve as well as what you need technically. There could - as always - be less involved ways to achieve what you need. Unless you are writing a security software or malware scanner or something super-involved.
And so it is clear: WiX's dark.exe fully decompiles MSI files into WiX source files and the resource files used to build them - you can then text and binary compare the various types of content (text compare for tables, binary compare for binaries, etc...). The process to do so via command line is described in the following answer: How can I compare the content of two (or more) MSI files? (this is about comparing MSI files, but one option to do so is to decompile them - see section on dark.exe - just for reference for others who find your question).
I like to link things together so we can find content easily at a later point in time. Strictly speaking it doesn't seem necessary here, you have what you need I think but others could perhaps benefit from some further links. Here are some related links:
Extract MSI from EXE.

How do I extract files from an MSI package? (explains why you should not use 7-Zip to extract).
I will have a situation soon where a file(s) will be automatically processed with a specific graphic (pre-press, .pdf files) software BUT a client(s) will be naming file(s) as they waht rather than sticking to the rules or suggestions. I will process the files, muti-page files will be separated (page splitting) into a single-page PDF files. After the whole process I'd like to rename those single-page PDF files to my needs when they end up in my final folder (my "OUT" hot-foldedr). I suppose it's good to mention that my software can handle .bat files. My hot-folder is on server so I believe that exact path have to be included. Or not? Server is Win 2008 SR2. Hmmm, what else could be important. Probably that's all at this moment.
Since I'm not a programmer can somebody please PLEASE help me with a .bat file solution? Please?
So, whatever the filename comes into my "IN" hot-folder will be processed and it will end up in some "OUT" hot-folder. When those processed files pops in that "OUT" folder I'd like them to be renamed according to my taste.
Example: "any_filename.pdf" --> "TEST-XX-DD-MM.pdf"
This "any_filename.pdf" should be renamed to "TEST-XX-DD-MM.pdf" and stay in that same folder.
I will automate my software further from there to send an e-mail to a client, send files further to a different process etc. This renaming is what gives me a headache now and I don't know did I mention, can this script be executed by itself? I have an option to put a module which is pointing (saying) my software to take a look at the script (if there's any) when files are in specific folder, execute (do your stuff) and leave files there. From there on I will handle this with no problem.
Thank you all for your time and patience and I'm really hoping I'm at the right place and someone will dig this, check out this post and help me out.
Big thanx to all once again!!!

We have subversion to help us manage our c files (and tortoise svn as front end).
When I want to know the changes in a c module, I (of course) only get the changes in the "body" of the program, not the changes in the include files.
So I wrote a small simple programm finding out all include files of a c module, checking the last subversion change date for each include file and writing the result in an output file.
This way I get a full impression of what has changed recently in the whole module.
But the program is very simple and I would like to know, if there is a solution out there that handles this "full view" of a c module in good way.
As I work on multiple independent change requests at one time in one subversion working folder, it does not help just looking at the result of "check for modifications".
Thanks a lot in advance.
Some handwork (onetime) required, but it can work
Using (file-level type for all files in every "project" /reqiure SVN 1.6+/) create virtual (or real) folders, which will include all files for each project. After it svn log inside such folder in WC will show only related to project-files changes
I am writing a script using Null Script which install around 6000 files in INSTALLDIR i.e. C:\ABC folder.
I have done this using
File /r "ABC"
in install section.
It is just a simple extractor (no registry entries and no uninstall.exe created during install).
Now, if I run the same exe again then I want my exe to display a message box to the user while overwriting the files containing the options
Yes,
Yes too all, or
exit the installer
i.e. How WinZip software does while extracting the same zip file in the same location multiple times.
If I set the SetOverwrite value to off then during install (2nd time) my EXE just skips the file installation without notifying the user. Also using IFFILEEXIST I can check a single file or *.* files but cannot do one to one mapping.
Please suggest how can I implement this. If this question is already posted then please send me the link.
Thanks in advance.
It is not possible to get this behavior in NSIS when using File /r. You might be able to pull off something similar by generating the file list at compile time by executing a batch file with !system and then check if each file exists and maybe delete the old one at run-time but you are not going to get the dialog without a custom plugin. NSIS itself only supports basic Abort/Retry/Cancel and Yes/No dialogs.
If you only want to use free tools, why not just use 7-Zip to create a self extracting archive?
I'm looking at an automated process (utilizing a "DOS" .BAT file) that creates zip files with a simple command like...
wzzip [path][zip file name] [files to be zipped]
...but when a partner receives and unzips these files, it's creating a folder with the name of the zip file and putting the files inside it, and they need (well, or at least prefer) it to just extract the files to the "." folder.
Is there a way to get wzzip to use "." instead of creating an eponymous folder? The only thing I could see in the options list was to maybe hack something out of -r-p (even though I DON'T actually want it to recurse folders when zipping), but I was hoping there might be a better way.
The partner company is apparently running Linux, so while I see that wzunzip has an option to set the output folder that MIGHT override the default behavior, I'm not sure what the app they are using might allow.
Go to http://www.winzip.com/ and download the Winzip Command Line utilities. Install and use WZZIP.EXE.
