This page collects the most common questions users ask about Qiling Safe Disk, from system requirements and encryption algorithms to password recovery and troubleshooting. If your question is not answered here, contact our support team.
Safe Disk creates password-protected encrypted containers (virtual drives) on any Windows PC. The questions below cover every part of creating, using, and recovering an encrypted container.
Safe Disk runs on Windows 11, 10, 8.1, 8, 7, Vista, and XP, including Home editions. It also works on Windows Server 2019, 2016, 2012, 2008, and 2003.
Yes. Unlike BitLocker, Safe Disk works on every Windows edition, including Windows 11/10 Home. No upgrade to Pro is required.
No. Safe Disk is Windows-only. To open a container on another operating system, run Windows in a virtual machine or use Boot Camp on a Mac.
Safe Disk works with internal HDDs and SSDs (IDE, SATA, M.2), USB flash drives (1.0, 2.0, 3.0), external hard drives, SD, MMC, and CF memory cards, and network drives such as NAS.
A 1 GHz processor, 1 GB of RAM, and at least 1 GB of free disk space. Most modern PCs exceed these requirements.
Yes. Safe Disk supports both 32-bit and 64-bit Windows.
Safe Disk offers four algorithms: AES-256, Blowfish, GOST, and 3DES. AES-256 is recommended for most users because it offers the best balance of security and speed.
No. Safe Disk has no backdoor and no recovery key. Without your password, the encrypted data cannot be opened by anyone, not even Qiling. This is by design. Always store your password in a password manager or a safe physical location.
Use at least 12 characters with a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid common words or personal information. A strong password is the only thing standing between your files and an attacker.
Yes. Open Safe Disk, select the container, and use the Modify Password option in the Mount dialog. Enter the old password and set a new one.
AES-256 encryption has never been broken. The only practical attack is a brute-force guess on the password, which is infeasible with a strong password. The biggest risk is a keylogger on the host PC, which is why keeping antivirus updated matters.
No. All encryption happens locally on your PC. Safe Disk never uploads, scans, or transmits your files.
Safe Disk creates a single encrypted container file. To achieve deniability, store the container inside another container or on a hidden partition. The outer layer reveals nothing about the inner one.
Each container can be up to 2048 GB, or 2 TB. For more space, create multiple containers.
A container reserves its full size immediately, even when empty. A 10 GB container uses 10 GB of disk space from the moment you create it.
Not directly. The size is fixed at creation. To get more space, create a larger container, mount both, copy your files across, verify, and then delete the old one.
Safe Disk uses the .fvd extension. It can also open .iso image files through the Add Old Image function.
Yes. Copy the .fvd file to a USB stick, external drive, or SD card and open it on any PC with Safe Disk installed.
Yes. The container is a single encrypted file. Upload it to OneDrive, Google Drive, Dropbox, or any cloud service and download it elsewhere. Your files stay protected because the encryption travels with the container.
Yes. Copy the .fvd file to the new PC, install Safe Disk or use the portable edition, add it through Add Old Image, and enter the password.
Safe Disk can keep the latest 2 to 32 backup copies automatically, which you configure in the Mount dialog. If the active container is corrupted, restore from one of these backups. Always keep a separate backup on another drive as well.
Yes. Use the Add Old Image function to load any .fvd or .iso file, including ones created with older versions of Safe Disk.
Click Create, choose a save location, set the size up to 2048 GB, pick an encryption algorithm, set a password, and click Create. A new drive letter appears in File Explorer.
Open Safe Disk, select the container, click Mount, enter the password, and choose a drive letter. The encrypted drive opens in File Explorer like any normal drive.
Click Unmount. The drive vanishes from File Explorer and your files are encrypted again. You can also enable Auto-unmount when user logs off for automatic locking.
Yes. Enable Mount as read-only in the Mount dialog. This lets you view files without allowing any changes or malware modifications.
Yes. You can mount multiple containers simultaneously, each with its own drive letter.
Files are encrypted on disk at all times. Mounting only makes them temporarily readable. When unmounted, the files are fully encrypted and invisible.
Yes. While mounted, the encrypted drive behaves like a normal drive letter. Any application can open, edit, and save files directly into it.
Yes. Send them the .fvd file and share the password through a separate channel, such as emailing the file and sending the password through a different app. Never send both together.
When enabled, Safe Disk saves a backup copy of the container every time you unmount it. You can keep the latest 2 to 32 backups, protecting against accidental corruption.
On modern CPUs with AES-NI hardware acceleration, AES-256 has a negligible performance impact. You will not notice a slowdown in everyday tasks such as opening documents or browsing photos.
Safe Disk creates an encrypted container, not full-disk encryption. For whole-drive protection on Windows Pro, use BitLocker alongside Safe Disk. Safe Disk is ideal for protecting specific files and folders with a separate password, especially on Windows Home.
Safe Disk works at the container level. Move the files you want to protect into the container, and everything inside is encrypted automatically.
An unmounted container is one encrypted file, so antivirus cannot read inside it. While mounted, antivirus scans the files inside normally. Keep antivirus running on the host PC to protect the mounted drive.
Safe Disk offers a free trial version. Check the pricing page for full license options and features.
The trial version lets you evaluate all features. The full version removes any usage limits and includes priority support.
License terms vary by edition. Check the product page for details on per-PC and multi-PC licenses.
Yes. Licensed users receive free minor updates and bug fixes within the same major version.
Unfortunately, there is no way to recover the data without the password. Safe Disk has no backdoor. Always back up your container and store the password securely.
Try mounting it with a different drive letter, avoiding letters already in use. If the issue persists, restart Safe Disk or Windows.
Double-check the password, including uppercase and lowercase letters. If you used a different keyboard layout when setting the password, switch to that layout before typing.
If you deleted the .fvd file, try recovering it with data recovery software first. If recovery fails and you have no backup, the data is permanently lost.
Compression will not reduce the size because the data is already encrypted. Instead, create a new container of the right size and copy the files into it, or split the data across multiple drives.
No. You can use both at the same time. BitLocker encrypts the whole drive, and Safe Disk adds an extra password-protected layer for specific files inside it.
Download Qiling Safe Disk and create your first encrypted container in under a minute. No credit card required.
Before changing security software or storage settings, create a full Windows backup. Qiling Disk Master creates a system image you can restore from if anything goes wrong.
Step 1. Open Qiling Disk Master and select System Backup to include Windows and the boot partitions.
Step 2. Save the image to a drive other than the Windows disk and start the backup.
Step 3. If a change causes issues, restore from the image to return Windows to its working state.
Safe Disk combines strong AES-256 encryption with a simple create, mount, and unmount workflow. The most important things to remember are to use a strong password, back up your container regularly, and keep the password somewhere safe because there is no recovery key.
