Keep a folder together and protect it before it leaves your device

This page is for the simple case where several files belong together and should stay together. Instead of sending a loose set of attachments, you can create one protected bundle, save it, and rebuild the contents later as a ZIP when you need them again.

Useful for

  • Small project folders, shared drafts and private handoff packages
  • Sending a protected bundle without relying on an account-based storage service
  • Rebuilding the protected folder later when the original files need to be restored

Good moments to use an encrypted folder bundle

This page is most useful when several files belong together and you want one password-protected handoff instead of many separate attachments. Think project documents, exported reports, photos for a client, or a small folder you want to keep together before moving it between devices. After unlocking, the page rebuilds the contents as a ZIP because that is easier to download and open again.

  • Use it when keeping the folder structure together matters.
  • Store the password carefully because the bundle cannot be reopened without it.
  • Use a clear folder name before encrypting so the rebuilt ZIP is easier to recognize later.

A practical way to protect a small folder as one bundle

When several files belong together, one protected bundle is easier to manage than many separate attachments. This page keeps that workflow direct: select a folder, create the protected file, then rebuild it later as a ZIP when you need the contents again.

  • Good for short project folders and private handoffs
  • Keeps related files together in one encrypted bundle
  • Lets you rebuild the protected folder as a ZIP later

How to use this tool

  1. Choose a folder from your device and enter a password.
  2. Create the protected bundle and save the .mfolder file.
  3. Return later with the same password to rebuild the contents as a ZIP archive.

When this page is useful

  • Small project folders that should stay together as one private handoff
  • Collecting several related files into one protected download
  • Keeping a password-protected archive before sending files to someone else

What to check before downloading

  • You need the same password later to rebuild the folder.
  • The rebuilt output is delivered as a ZIP so it is easier to download and reopen.
  • This is meant for practical browser-side protection, not a multi-user storage system.

Privacy note: The encryption flow is designed to work locally in the browser so the folder does not need to be uploaded to an account-based service first.

Questions people usually have before they save the result

Is Folder Encryptor designed for private files?

Yes. This page is for people who want a straightforward browser tool for protecting files with a password before storing or sharing them.

What should I remember before downloading the protected file?

Keep the password safe and test the unlock flow before you rely on the protected file. If the password is lost, you may not be able to recover the original content.

Why would I use Folder Encryptor instead of a larger app?

It is useful when you want one clear password-protection step without setting up a larger desktop program for a small encryption task.
