1. Decide what needs encryption
Choose whether you need to protect the system drive, a data partition, an external hard drive, a USB drive, or an SD card.
Encrypt a Hard Drive Before Data Leaves Your Control
Windows login passwords help control normal sign-in, but they are not the same as encrypting the data stored on a hard drive. If a drive is removed, connected to another computer, or accessed from a different startup environment, unencrypted data may still be exposed.
Full hard drive encryption is designed for data-at-rest protection. It is useful for business laptops, desktops with confidential records, field-service computers, office workstations, removable storage, and any Windows system that stores customer files, finance records, HR documents, source materials, or private archives.
Recommended choice: use GiliSoft Full Disk Encryption when the goal is encrypting a whole hard drive, data partition, USB drive, or SD card. Use File Lock Pro when you only need selected folders or files protected.

2. Back up important files
Before changing drive security, keep a verified backup of important documents, business files, photos, and recovery information.
3. Open Full Disk Encryption
Install and open GiliSoft Full Disk Encryption on the Windows PC, then select the drive or partition that should be encrypted.
4. Set access credentials
Create the password or access settings required before protected data can be opened, mounted, or used in the approved environment.
5. Start encryption
Run the encryption task and allow the process to finish without interrupting the computer or disconnecting the protected drive.
6. Test access after encryption
Restart or reconnect the drive as appropriate, confirm the access prompt works, and keep recovery details in a secure place.
Hard Drive Encryption vs Folder Protection
Hard drive encryption protects the storage layer
Use full disk encryption when the entire drive or partition must stay protected if the device is lost, removed, or accessed outside normal Windows sign-in.
Folder protection is better for selected data
Use File Lock Pro when the job is hiding, locking, encrypting, or monitoring specific folders, files, or private drives inside Windows.
USB Encryption is for removable delivery
Use USB Encryption when the main target is a USB flash drive or removable media that needs a password-protected secure area.
Full Disk Encryption is for data at rest
Choose Full Disk Encryption when the important risk is stored data on a hard drive, partition, laptop, desktop, USB drive, or SD card.
BitLocker vs GiliSoft Full Disk Encryption
BitLocker is the built-in Windows route
BitLocker can be a practical built-in choice on supported Windows editions and hardware when users already manage Microsoft drive encryption.
GiliSoft focuses on a dedicated encryption workflow
GiliSoft Full Disk Encryption gives users a product focused on drive and partition encryption, removable-media protection, and practical endpoint data protection tasks.
Use the tool that matches the device
For whole hard drives and partitions, choose Full Disk Encryption. For USB delivery, choose USB Encryption. For selected folders, choose File Lock Pro.
Keep passwords and recovery details safe
Any hard drive encryption workflow should include a secure record of passwords, recovery information, and who is authorized to unlock protected storage.
Common Hard Drive Encryption Use Cases
Encrypt a business laptop
Protect documents, client files, spreadsheets, reports, and project materials when a laptop travels outside the office.
Encrypt a data partition
Use a protected partition for finance, HR, legal, product, research, or customer records that should remain unreadable without authorization.
Encrypt external hard drives
Apply password-based protection to portable drives used for backup, field work, media transfer, or archived project storage.
Protect removable media
Use drive encryption for USB drives and SD cards that may contain exported data, installation files, training assets, or portable work documents.

Yes. You can encrypt supported hard drives, partitions, and removable storage using a full disk encryption tool such as GiliSoft Full Disk Encryption.
Is hard drive encryption the same as password protecting a folder?
No. Hard drive encryption protects storage at the drive or partition level. Folder password protection is better when only selected folders need access control.
