How to Delete Files from Archive by Text File

I attempted to use the for / i loop to get 7zip to refer to the list, but it kept trying to open the text file as an archive. I'm looking for a technique to automate the deletion of the JndiLookup.class file from all log4j files that contain that class. Because they are not in a fixed location, I planned to dump the sites into a text file using PowerShell or wmi. What can I do?

The process is comparable to renaming a file inside a zip archive. You'll need to unzip everything, create a new file or replace the existing one with the extracted data. Therefore, proceed as before but omit the problematic file.

Given the large number of log4j files scattered around the system, you can point 7zip to a relative path. It will remove the files inside the archive, which are .jar files, close them without extracting them, and zip them back up. Because, as known, the files are dispersed, there is no way, at least that we have discovered, to have 7zip recursively execute it. We thought we could have it refer to the text file that gives the locations of all the files, but it didn't work.

Although 7zip allows using a text file, such as @somelistfile.txt, it only appears to work for creating archives, not deleting files from archives.

However, suppose you insist on renaming or deleting the file without opening a temporary directory of the zip files from the archive. In that case, you may pay attention to corrupting the files on your computer.

If the invalid ZIP files or folders are no longer accessible on your computer, try to fix them to work correctly. If you simply cannot open or utilize the ZIP file or folder because it displays an error message indicating that the compressed or zipped folder or file is invalid, as seen below, proceed to restore corrupted invalid Zip files immediately.

And relax if you can't find the ZIP file on your computer or external hard drive. It was most likely removed from Downloads or was not saved in the standard location on your devices.
