How do I open a zip file with password protected Word files inside?


Question

How can I open a zipped file that has password protected Word files inside? The zip file itself is not password protected. However, having forgotten the old passwords associated with the documents, I'm unable to unzip the password protected files that're located inside the zip... the Word files themselves won't "unzip," because of the password. I am able to get into my passworded files that are not located inside of the zip, but can't get to the files inside the zip.

Any suggestions/solutions?

That means the .zip file itself has password protection. When a .zip file has password protection you can still open/browse the contents without a password, the password is only needed when attempting to unzip any of the files inside.

Can't really give you any suggestions offhand, .zip file passwords are pretty hard to crack unless it's an easy password that you can guess via a dictionary attack.

The Word files inside of the zip that are not password protected unzip just fine. It's the Word files that are passworded that won't unzip.

In the unzip wizard, it does ask "if there are any files inside the zip that require a password, enter them now." I don't remember the passwords to the ones within the zip, therefore the unzip wizard won't unzip the file. If I can get the unzip wizard to at least unzip the file, then I have a way to recover my password. The recovery software won't acknowledge Word files within a zip.

"if there are any files inside the zip that require a password, enter them now."

I'm pretty sure it's talking about the ZIP file itself and not the Word documents inside.

Assuming you may be correct though, try using a different program to extract the ZIP archive.

yeah Im curious what zip software you are using? Cause I can assue you a word document having a password set in word on it would have nothing to do with it unzipping from a non-passworded zip file.

You do understand that you can password protect certain files inside a zip, while others are not.

If we knew what application you were using to work with the zip files, we would know what features it supports or does not support, etc.

Example.. As you can see here in this test.zip I created.. file1 and 3 are not encrypted "password protected" but file2 is.. I can unzip file1 and 3 with no problems, but if I try and unzip file2 it asks for the password. This is the ZIP password, not any password what would of be set in whatever application the file might be.

I suggest you test it yourself, create a test word document - put a password on it in word.. Then zip it and unzip to your hearts content. Some password that word places on a file would have no effect on zipping or unzipping the file.

As to defeating the password on the zip.. That would really depend on the level of encryption used.. If its the newer AES 256 that lots and lots of zip programs use -- good luck! There are tools out there to bruteforce the passwords, but if you used any type of decent password your pretty much out of luck.. The speed of these bruteforces are very very slow, so a decent length password could take quite some time to find.

edit: I created a AES-256 encrypted zip.. Look at the speed -- it would TAKE FOREVER to find a very weak password.

but on older encyption method. Its very fast.

edit2: BTW these speeds are on a quad 2.4 ghz box, so your not going to see much faster than that 120 some passwords per second for AES no matter what normal pc hardware you try and bruteforce it on.

So in the 7zip manager does it show the Encrypted + like in my screen shot? Could you post up a screen shot of the 7z file manager with the zip file open.

    • Here's my scenario: I have an intel i5-10600 based system using a Gigabyte Z590 Aorus master motherboard with an EVGA GeForce GTX 1070 (non-TI) graphics card. The PC has three monitors, 2 x Dell SE2717H/HX and an older Samsung monitor. The monitor configuration is Dell SE2717H - Samsung, Dell SE2717H. (1) The left Dell monitor is connected to the 1070 by via DP out on the 1070 (DP to DVI adapter connecting DVI to HDMI cable) going to HDMI input on the monitor. (2) The center Samsung is connected to the 1070 via HDMI output on the 1070 to HDMI input on the monitor itself. However I have a HDMI duplicator connecting the Samsung monitor to a NanoKVM box. Will explain this more in a moment. (3) The right Dell monitor is connected via a DP to HDMI cable. It's connected to DP out on the 1070 and HDMI input on the monitor. When the PC is powered on, the right (3) monitor is the default monitor showing the BIOS and POST screens before booting into Windows where the center Samsung becomes the primary monitor. I have the Samsung set as the primary in Windows, but that obviously doesn't affect the BIOS/POST. I had swapped the right Dell and center Samsung thinking the monitors were dictating the settings, but when I reconnected them, the Samsung was on the right, it still remained the priority monitor during BIOS/POST time. So I reverted those changes. I followed the EVGA card port priority per this official EVGA page ( https://www.evga.com/support/faq/FAQdetails.aspx?faqid=59560 ) which indicates the following priority of ports: - DVI - HDMI - DisplayPort (middle) - DisplayPort (far right) - DisplayPort (far left) With the DVI port not in use, I verified the center Samsung monitor was on the HDMI port on the 1070. The left Dell monitor was connected to DP (middle) and the right Dell monitor was connected to DP (far right). However during BOOT/POST, the right Dell remained the priority. I created all sorts of combinations of moving the center Samsung to the middle DP port (using DP to HDMI adapter), for the higher priority # and moving the left and right Dell monitors to far right and far left DP ports. However the right Dell monitor remained the BOOT/BIOS priority default. Why does this even matter?? The reason I'm trying to solve this puzzle is because I recently purchased a NanoKVM PCIe card that gives full BMC access to the BIOS and visuals via HTML5 web interface to pre-Windows boot time. In the event I need to troubleshoot when I'm away from home. The NanoKVM has an HDMI input port so it can grab the screen and share it via the HTML5 built in portal on it's remote IP access. Because the NanoKVM isn't multi-monitor aware, it's designed to only display the monitor that it's plugged into in the video card so I can see the  boot /BIOS screens and the Windows default monitor. Because there is no HDMI passthrough on the NanoKVM, I purchased a HDMI duplicator/splitter (NOT an extender).   This HDMI extender connects to the HDMI output on the 1070. My center Samsung monitor is connected to splitter output port #1 with a standard HDMI cable and the NanoKVM is connected to splitter output port #2 with a standard HDMI cable as well. When I disconnect both Dell monitors and leave this setup connected to HDMI, it works flawlessly. When I connect the left Dell monitor to the above far left DP port on the 1070, the setup still works great as the center Samsung still remains the default/priority. But when I connect the right Dell monitor to the far right DP on the 1070, the right Dell becomes the default/priority monitor during BOOT/POST time. This results in the NanoKVM not having access to/displaying the contents of the right Dell when it's priority during BOOT time, but once the PC boots into Windows and it's the default monitor/port, the KVM displays that just fine then. However, this defeats the purpose of needing the KVM which is to provide access to the BIOS and boot menu settings in the event of an emergency while I'm away from home. Any idea on what I'm doing wrong? Do I need to replace the center Samsung?? Different monitor / adapter cables??? Do I need to upgrade the video card? I have a 980Ti, but per the EVGA docs, the port priority is the same for it as the 1070. Thoughts?? Suggestions???
    • I've had the Ryzen since it first went to market. I've had Windows 11 since beta testing it in the early days... Ryzen worked just fine, Windows didn't... so, not sure what this "four years" it is you're referencing since you're not specific as to who fixed what.
