How can i tell 7z to extract all the files in the directory, tell it to do not replace files that have the same name but different hash? preferably tell it to extract the files and rename them to their hash?
for example lets say i extract two zip files, both have x.dll but with a different hash (different version). i want to keep both, but if its the same version (same hash), then only keep one. and preferably rename the extracted file to its hash, how to do it?
Right now I am extracting this way :
7z -y -aot -p"pass" x "*.*"(not all the files contain password, but if they do, its the same, so correct me if I am doing it wrong)
To give context, i have a large number of installer files (.msi or .exe files that contain a lot of exes inside them), and i need to extract all the unique executables inside of them
Right now i am using the linux version of 7z, but i can use the Windows version too (inside a VM)

So, this is my \Test Folder\*.*:
I:\> tree /f /aFolder PATH listing for volume 2ndHD
Volume serial number is FACF-B9ED
I:.
