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?

Just the title. I'm trying to make a .bat file that moves stuff into a .jar, but I have no idea what to do, or even if it's possible. If it's possible, could I be pointed towards the information that would allow me to create such a .bat file? Thanks.
"A .jar file is just a .zip file with a different extension. Use any zip tool that takes command line parameters like WinZip or 7-Zip, and call it from your batch file passing it the right information in the parameters to add the files. Once you pick your utility app, you can read its documentation to find out what parameters it takes and what order they should be in. (Or more easily, you could just open the file in WinZip or 7-Zip and drag and drop the files in using Windows Explorer and save the time and effort.)" - From Ken White, in a comment
Thank you Ken White, for your answer.
While I do agree not using commands is more convenient, I can't automate moving files without commands or code.
This is a valid answer. But for some reason an arbitrary restriction won't let me mark this post as the answer until two days.
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
I'm using psftp.exe to download files from the server. Is there an easy way to delete these files once I have downloaded them but leave the new ones that might have appeared on the server when I was downloading to be downloaded next time?
Here's my command line:
psftp.exe domain.com -i keys\private.ppk
get *.xml
Edit: I want to download the files from a Linux box to a Windows PC.
There's no easy way to do this with psftp. You would have to parse its output to find files that were successfully downloaded.
Though you can do this easily with WinSCP. Just use get -delete *.xml command.
Full WinSCP script would be:
open sftp://domain.com/ -privatekey=keys\private.ppk -hostkey=...
get -delete *.xml
exit
See an introduction to WinSCP scripting.
See also a guide for converting PSFTP script to WinSCP.
You can also have WinSCP GUI generate script like this for you.
(I'm the author of WinSCP)
Martin's answer is good. The below is more industrial.
Moving them to a staging area before the download may be prudent.
Generally you would move/rename the files on the server as a starting point. They are going to be deleted anyway so nothing should miss them? nor would you want to fall back over a recent file.
(so restart after this point in the event of a subsequent failure)
Then perform the download.
Then perform the delete.
I would approach the issue differently. Instead of deleting the file from the server, add the downloaded filename to a local table of "Already downloaded files". Then when you scan the FTP again for new files, ignore any that are in that table.
That way the next time you run your download script you only get the new files, but the old files remain on the server.
You could have another script that runs periodically and deletes all files over a certain age.
WINSCP is alright, and Martin (the author) drops in to practically every PuTTy thread to recommend it, but it's a fully GUI-based app and not for me. If you really need everything to be done on the commandline then WINSCP is often not an option.
Okay I currently need to check about 200 files, so of course i want to automate as much as i can. the software I need to use to inspect them does not seem to have a command line interface, so I am currently stuck right-clicking them and clicking edit.
Is there any way to access that edit command from command line, so I can automate this process, or am I stuck opening 200 files like this.
Okay I figured it out, and here's how I did it!
Go to regedit, and find the file extension im trying to deal with in HKEY_CLASSES_ROOT
then inside the folder for the file extension i found the name of the folder of the program this filetype uses, and that folder was also located on HKEY_CLASSES_ROOT.
Then inside that folder is a "shell" folder wherein all of the contextual options are located.
That shell folder had an element called "edit" and that element contained a shell command that was used behind the scenes to launch the editor with the specific file.
Now I can write my batch script with this command!
I have a script (a.bat) that calls 2 executables (b.exe and c.exe) and I would like to create a single exe that would call a.bat automatically.
Is it possible?
Any simple program to do this?
Ps.: Info: The Exe's do make other files that are deleted in the end
Not directly, no.
The simplest way to accomplish this with off-the-shelf tools is to use an archiver that can create self-extracting archives and allows to specify a file to run after extraction. For example, free Info-Zip tools support an autorun command. WinRAR (commercial) allows to define complex scripts with GUI.
An install engine can be used for the same purpose. For a couple of examples, there are NSIS and Inno Setup (both free).
A (relatively) more complex solution is to write a third executable that will extract payload from its resources and run the batch file. This way you have full control over what happens.
This One:Bat To Exe Converter
It has the "Include" option that can include the exe file
when the compiled exe file run
it will release it
and you can run it!
