not sure if it is good place to ask this question: I bought a legacy software running on Windows XP. it comes with 7 disks(installation).
to make a backup, is there a good way to merge these 7 disks into one CD?
Thanks a million!

During the Windows XP era it was common to implement DRM as physical defects on the media. Literally bad sectors/tracks on the physical media. So maybe you can back it up... if the disks are not protected.

Chris Wu wrote a powershell cmdlet that can easily make an ISO. It uses the Image Mastering API

Note that a CD is ~700MB so combining seven of them would barely fit on a DVD.

thanks for the info! my disks are just floppy disks, so the size is fit for one CD without any problem.
I checked your link and did not see any examples on how to use this Powershell tool. any examples to share?

Go catch your own fish. It can't be that hard to execute a powershell script.

I know how to run powershell, but from the link you give me, I saw source code defining this function:
function New-IsoFile
{
................
}
shall I copy this function into a text file and then save it as .bat file?

You do realize that this is the Lounge right? I am drinking a glass of red wine and could not care less about the outcome. powershell files have a PS1 extension. I am not in the mood at the moment to hold your hand. Ask me tomorrow

thank you very much for sharing this info! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) I will buy this tool to create my ISO. I got one more disk set to backup...

The responses so far suggest to create ISO files or equivalent of the original floppies, which is going to be a little annoying when installing - mount a file, let it copy, dismount it, mount the next, etc. Although it probably is the method that's the most likely to work.
But it also depends on the installer on those floppies. Some installers will be perfectly happy to keep going if they can find the files it's looking for - if it can't, that's where it pauses everything and asks you to insert the next disk. But I've absolutely seen cases where, if you dump all files from all disks into a single folder then run the installer from there, it'll blast through the installation process without ever stopping, as long as it can find (for example) disk1.cab, disk2.cab, [...] diskN.cab.
That approach won't work however if you have files with identical names but with different content on each disk.
In a case like this, you might be able to get away with creating subfolders (disk1, disk2, [...] diskN) with a raw xcopy dump of the original disk in each corresponding folder (then it won't matter if filenames clash). When the installer is done with disk 1, it'll stop and ask you to provide the path to disk 2, at which point you just have to replace the disk number in the path displayed, and it'll carry on. Still a lot quicker than mounting/dismounting ISOs.
But again, it really depends on the installer. If you don't know your way around a file system, I don't recommend the experiment and would just go with the ISO suggestions.

I looked at each disk, for each disk, there is a file named as DISK_1 for example, its content is string "TS_1"...
I consider if I can combine them into one big file ....

I suspect this is not gonna work, as changing the content of any file will, well, no longer match what the installer is expecting. You might be able to get away with it (depending on the installer), but I think the odds are stacked against you in this case.

I got what you said. I will create sub folder under current folder etc. to see if this trick works.....

wrote code, ran into 1000 item limit. put i+=1 and if else and broke into multiple uploads.
I know there is probably a cleaner way to do it. But it is Friday afternoon and Well I wanna get this done and go home.
I don't blame myself but I know in 6 months when I look at the code I will wonder what I was thinking.

If you use visual studio put // TODO: Fix this and make it work better or similar and then you can look at all your TODOs by going View|Task List in VS2019 (should work with older versions too)

Yes, you can. And you might even create tech debt items to track them in your favorite issue/project tracking system. And monitor their presence/growth over time in a nice dashboard. But it's unlikely you'll ever fix them.

That's fair enough. I don't disagree. The problem is that I've had managers who do. Make the best of what you have to work with.

Make sure to comment it.
That should tell everyone what they need to know about the code that follows

Does anyone know what the simplest circuit to use for a 16 pin LCD hitachi style display is to make it display *anything* or even turn on the backlight?
I got a new kit and I can't seem to get the LCD display to respond at all, and I'm not finding the answer to this anywhere. All the examples I can find use a library, and require the thing to be fully wired up. The problem is, after having done that, even after double checking and triple checking my wiring against the examples it still didn't work. I need something simpler just to do a basic power-on sanity check for the LCD.
I have no idea what the hitachi display protocol looks like in practice and the pins aren't very descriptive.
I know there are some arduino-heads here on CP. Can I get that LCD to do anything at all with two or three connections?

Is it a 5 volt display or does it use some other voltage?
Are you sure you have the power connected to the correct pins?
The difficult we do right away...
...the impossible takes slightly longer.

It's 5vdc from the looks of it. I would think I'm certain having checked multiple times, but the display disagrees with me, since it just sits there dead as a fish when it's supposed to be printing "Hello World"
I need to order a multimeter from amazon. I suppose I'll do that today.
