The File Appears to Be Encrypted
Sometimes users contact us saying that a lock icon appears on a file or folder and that they are unable to open it. First, we will guide you through a few things to check and possible solutions.
First, regarding the SecretFolder program, this program does not provide a feature that adds a lock icon to file or folder icons. SecretFolder provides a folder-hiding function, but it does not encrypt files or folders or display a lock icon. Therefore, if a lock icon is being shown, it is highly likely that it is not related to the SecretFolder program.
If a lock icon appears on a file and access is restricted, it is important to look into other possible causes. One of the most common causes is BitLocker encryption, which is built into the Windows operating system. BitLocker is a security feature that encrypts files or drives, and it may be enabled according to IT management policies, especially in company or organizational environments. In this case, the file or drive showing the lock icon may be protected by BitLocker, and it may not be accessible without the correct recovery key or password.
To check whether the file is locked because of BitLocker, we recommend first checking whether BitLocker is enabled on the computer you are using. If it is a company-managed computer, the fastest solution is to contact your IT department or system administrator to check whether BitLocker is enabled and to get the recovery key if needed.
If it is a personal computer, please follow the steps below to check whether BitLocker is enabled:
- Check BitLocker settings: Type "Manage BitLocker" in the Windows search box and open the BitLocker settings screen. There, you can check whether the drive is encrypted.
- Check the recovery key: If BitLocker is enabled, you may need a recovery key. This key can usually be obtained from your Microsoft account, a USB drive, or your company IT department.
- Check administrator permissions: Sometimes a lock icon may appear because of file access permission issues. Right-click the file and check your account permissions under "Properties" โ "Security."
If the lock icon is caused by something other than BitLocker, you may also need to check the following:
- Third-party security software: Certain security software or encryption programs may have locked the file. Please check the list of installed software to see whether there is any program related to file encryption.
- File system errors: A problem with the drive's file system may have corrupted the file or restricted access. In this case, running the "chkdsk" command to check the disk may also help.
If you would like more detailed information or need additional guidance on BitLocker recovery, we recommend referring to the BitLocker documentation provided on the official Microsoft website. You can find detailed help at the link below:

Anthropic Unveils โChannels,โ a New Way to Control Claude Code Sessions Directly from Mobile
Anthropic has introduced Channels, a new feature that makes it much easier to use Claude Code in mobile environments. With this update, users can control their AI coding agent through messaging apps like Telegram and Discord, sending instructions from their smartphones as casually as they would text a friend.
At launch, Channels supports Telegram and Discord first. This means users no longer need to be sitting in front of a desktop development setup to interact with an active Claude Code session. Whether they are commuting, away from their desk, or simply on the go, they can reconnect to an existing session and send prompts in real time. Requests like โcheck that error again,โ โsummarize the test results,โ or โcontinue refactoring that codeโ can now be handled directly from a mobile device.
What makes this update especially interesting is how it expands the development environment into communication tools people already use every day. Until now, coding agents were typically accessed through traditional developer interfaces such as IDEs or terminals. With Channels, familiar messaging apps themselves become the interface for directing the agent. Instead of learning a new workflow, users can collaborate with AI in an environment that already feels natural and intuitive.
Another important aspect is continuity of context. This is not just about sending isolated commands from a phone. Users can stay connected to the flow of an existing session and continue work without losing momentum. That makes the feature especially practical for developers who are in meetings, traveling, or working asynchronously with teammates. Even when they are away from their main machine, they can still monitor progress and provide instructions as needed.
Ultimately, Channels makes AI coding agents more accessible, more lightweight, and more integrated into everyday work. It reflects a broader shift away from development environments tied to a single device or location, and toward workflows that can continue anywhere. If Anthropic expands platform support and continues refining the experience, messenger-based AI development workflows could become mainstream sooner than many expect.
