Truly Portable Encrypted File Access

mbone — Sat, 03 Jan 2026 18:54:56 +0000

I'm setting up a USB drive with a password manager, for my wife to use in the event of my death. I considered using a bootable linux setup, but I've seen enough hardware compatibility issues that I'm not confident leaving my wife with potential technical problems. And even if no hardware problems, I don't want her to have to figure out how to boot an external drive as it varies on each system. So I decided to try a windows portable app setup. We may have a computer for her to use, but not guaranteed, so I'd like for her to be able to use someone's computer with the portable app USB drive. It would probably be owned by someone we know, rather than something public at an internet cafe, which reduces the threat somewhat, but I would still like to be considerate of the owner and not make any changes to their system.

I have the main function working well: a portable browser, portable keepassxc with a database on the drive, and the keepassxc browser extension already installed. It's setup to start the browser and open the keepassxc database on launch, and it connects the password database to the browser extension, so it's ready for her to enter the keepassxc password and navigate to web sites where keepassxc will provide the passwords.

However, there's one additional piece I'd like to setup. I'd like to create a document (could be html or pdf) with account numbers and explanations that should be kept secure, so stored encrypted on the drive and only accessed by the portable apps on the drive. I've tried two methods, but both have issues that I'd like to avoid, so I'm asking for ideas on other apps or methods I could try. Here's what I've tried so far and what issues I've encountered.

1) Store the document as an attachment in a keepassxc entry. The problem with this is that the portable keepassxc app will only open the document in the default browser or default pdf app, which will be the browser/app installed on the host machine, not the portable browser/app on the USB drive. I'd rather not change the default apps on the owner's machine, and letting it open the document in an installed app is something I'd like to avoid as well.

This would work if there was a way to get keepassxc to point to the portable browser instead of just using the default app on the local machine, but I don't think that's possible. One idea that I haven't tried is to use the keepassxc command line app with the "attachment-export" option to store the file on the USB drive, or send it to stdout. Maybe a batch file could be setup and run from the portableapps launcher to do this, but if storing as a file, there would need to be a way to securely delete it after reading so it doesn't remain in plaintext on the drive. Keepassxc does this automatically when opening an attachment from the gui. But it first stores the file in plain text on the host machine, and opens it using the default browser, before wiping. I would still prefer that the document stay on the USB drive. Alternatively, maybe the stdout export option could be used to pipe the document into the browser, but I'm not sure if a temporary file would be stored on the host machine in that case. Also, I'd like to keep this simple and automated so my wife doesn't need much technical knowledge to use it. Anyone get something like this to work in an automated way?

2) Store the document in an encrypted container using veracrypt portable. As the veracrypt installation notes say, it is not truly portable because drivers need to be installed on the host machine to allow on the fly encryption, and it requires admin rights. Would rather not ask anyone to allow admin rights so that drivers can be installed.

Anyone know of a way to do this that doesn't involve any of the following?

Opening the file in an app installed on the host machine
Installing anything or leaving anything behind on the host machine
Requiring admin rights
Changing the default browser

KeePassXC Browser integration

StephanP — Fri, 28 Nov 2025 14:24:20 +0000

I've got the MS Store version of KPXC installed on my school laptop and wanted to try out the PortableApps version of it.

Unfortunately I couldn't get the browser integration to work.
After I had enabled browser integration within KPXC Portable, establishing the database connection between KPXC Browser extension and KPXC Portable failed without any feedback.
- Does KPXC Portable not support browser integration with the KPXC Browser extension installed on a supported browser?
- Could it be that the installed MS Store version of KPXC is confusing the system and causing the database connection to fail?

Since it took some persuading to have my ICT dept install KPXC for me (no admin rights), I am hesitant to uninstall the MS Store version in order to fully test the KPXC Portable independantly.

[Fixed] ClamWin no longer able to update virus definitions

daven2411 — Thu, 02 Oct 2025 08:40:14 +0000

Update has been failing for last couple of days. According to their website, the version that PortableApps uses is End Of Life. Could this be the cause?

[Fixed] Trellix Stinger Stealth drops McAfee security and leaves it there running

Nergal Cuthah — Wed, 16 Jul 2025 18:53:30 +0000

After running a scan with Stinger a folder with a running version of McAfee security, including at times the firewall application. As this McAffe is not installed only placed one must run the McAfee uninstaller application (https://www.mcafee.com/support/s/article/000001616?language=en_US)

While this is concerning for the non-portable version, it is troubling for PortableApps suite as it leaves this behind. There is a Window XP warning at the beginning of the first open of stinger but makes no mention of this embedded Security software that may conflict with installed security.

Did not mark this as a bug as I think it's intentional on McAfee's part. I have a screenshot of the folder but don't see a way to add it to this post.

The McAfee remover is no-install and takes about 10 min on a 2022 computer.

keepassxc doesn't remember you were using a key file, nor the directory

MaximilianKohler — Mon, 30 Dec 2024 02:58:11 +0000

As long as you're not moving the folder it remembers it correctly. But once you move the portableapps folder to another location, keepassxc only remembers the database.

KeepassPro remembers everything and doesn't have this problem.

I'm not sure whether this is an issue with the portableapps.com config files or if the XC devs need to improve something.

Microsoft Safety Scanner via mssPortable_not downloading

Knightmare_ — Tue, 30 Apr 2024 17:31:04 +0000

Hello and Good Morning,
The last three times I tried to update Microsoft Safety Scanner I get the following error.
---
Unable to download the file. This could be due to a proxy or
network issue or the hosting server not permitting downloads from
your location. File:
https://go.microsoft.com/fwlink/?LinkId=212733
---
Now, I was able to go the Microsoft Safety Scanner Download webpage,
https://learn.microsoft.com/en-us/defender-endpoint/safety-scanner-download
and use the same link on that page
https://go.microsoft.com/fwlink/?LinkId=212733
to download the 32-bit version.

Then I downloaded the 64-bit version from
https://go.microsoft.com/fwlink/?LinkId=212732.

NOTE: Both the 32-bit and 64-bit files are named MSERT.exe

So, I renamed the 64-bit file to MSERT64.exe and copied both files
to this directory. drive:\PortableApps\mssPortable\App\mss
---
I don't know why I get the error using the PortableApps updater.
Like I said above, this has just started happening.

Oh!
Before I forget, my system is Windows 7 64-bit.
If you need more information, let me know.
Thank you, Dan

KeePassXC Portable Single Instance support

hgtok — Wed, 17 Apr 2024 06:47:13 +0000

(Cross posting to Development Forum https://portableapps.com/node/71332)

Hi, I would like to request for proper support for single instance in the Launcher.

The app has an option to toggle single instance, but the Launcher ignores it and runs multiple instances.

According to https://portableapps.com/manuals/PortableApps.comLauncher/ref/launcher.i..., the SinglePortableAppInstance flag is false by default, which should resolve this issue.

Thanks
