I am writing a nodejs script which should do the following:
Replace 10 or more bmp files within the zip
Because the zip file is large, I would like to replace the files without unzipping and rezipping the file.
Is that possible?

Let say I have a zip archive test.zip which contained two files:
test1.txt and text2.txt
I want to extract only test1.txt using the node inbuilt zlib module.
How to do that?
I don't want to install any package.
You could run a shell command to unzip, assuming that unzip is installed on your system. (It very likely is.)
As far as I can tell, there is no zip functionality within node.js without installing a package.
You can use zlib to help you with the decompression part, but you will have to write your own code to interpret the zip format. You can use zlib.inflateRaw to decompress the raw deflate compressed data of a zip entry. You have to first find where that compressed data starts by reading and interpreting the zip file headers.
The zip format is documented here.
I want to extract a ZIP File with the .exe inside.
I want to execute the .exe inside the Zip to extract the Zip File.
Already tried it by executing: ZipDLL::extractall "$EXEDIR" "$DESTINATION"
I think that does not work, cause the .exe is stored in the TEMP Folder when opened, so it cannot find the.Zip file
So how do I extract that Zip when executing the .exe from inside the Zip?
Thanks for answers!
Your question does not make a lot of sense, you should just put the files inside the installer and not have a zip file at all.
Even if it made sense, it is not possible because where a exe is executed from when you double click it inside a zip file depends on the zip program you are using and there is no way of getting the path of the zip it was extracted from.
If for some reason you want to be able to update the files inside the zip file without rebuilding the installer you can use a cab file instead. The CabX plug-in supports extracting from cab files appended to the installer exe.
Is there any node library which able to unzip split zip files? Or any other way? I have tried a lot of node libraries but no luck.
I am receiving files like below.
test.z01
test.z02
test.zip
I need to extract these files.
Is there any ways to compress a file from my_file.txt to my_file.zip using ionic 3? I've found the ionic plugin that only can unzip the files but not to zip the files.
Reference:

Anyone? Thanks for any helps or comments.
I would suggest client zip, You can fetch your text file in the downloadzip()
function , and this function will return you a zip blob file which you can convert into a zip file.
How can I verify that the unzipped files are not corrupted after the extraction from the zip file?
Scenario: I am packaging some font files via 7zip and then during installation of the application I am unzipping it and copying it to some specific directory. In some cases, although my unzipping is successful my unzipped files are coming to be corrupted. I am not able to load the font files. Upon investigation, I found that they are somehow getting corrupted.
Is it possible that during extraction, extracted files can get corrupted?
What is the way to check if the extracted files are fine or corrupted?
I can test the zip file using -t flag which checks that all the files are correctly zipped in the zip files but what I want to check is that POST extraction whether the files corrupted or not?
Thanks
