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:

Download Useful External Codecs
If you want to use various video codecs with oCam, you can install external codecs to adjust recording quality and file formats the way you want. Below is information about the external codecs supported by oCam and how to install them. Installing external codecs allows you to use oCam more flexibly.
After installing an external codec, you must restart oCam. Once restarted, the installed codec will automatically appear under the 'External Codec' option in the oCam settings menu, where you can select it for recording. External codecs can be downloaded from the following link:
https://ohsoft.net/update/codec.php
The following are descriptions of the main external codecs supported by oCam:
Xvid Video Codec
The Xvid codec is a video codec that implements the MPEG-4 Simple Profile and Advanced Simple Profile standards. This codec offers efficient compression and high compatibility, making it suitable for creating videos that can be played on a wide range of devices and software. With Xvid, you can keep file sizes reasonable while minimizing quality loss during recording.
x264vfw Codec
x264vfw is a VfW (Video for Windows) codec that includes the widely known x264 encoder and ffh264 decoder. Based on the H.264 format, this codec can save high-quality video in a smaller file size. x264vfw is especially suitable for users who want sharp image quality and efficient compression, and it also offers excellent compatibility with various video editing software.
VP8 Codec
The VP8 codec can encode video at quality comparable to or better than H.264 video encoders. VP8 is a core component of the WebM format and is well suited for web-based video streaming or high-quality video storage. With this codec, you can reduce file size while maintaining clear image quality for efficient recording.
Lagarith Codec
Lagarith is a lossless video codec designed for video editing and archiving. As a lossless codec, it preserves the original video quality exactly, but the file size can be relatively large. Therefore, it is suitable for users who want to edit high-quality video or store it for the long term.
By installing and using external codecs in oCam, users can choose the best codec for their recording purpose and environment. For example, if you want to reduce file size, you can choose x264vfw or VP8, and if you want to create editing footage without quality loss, you can choose Lagarith. Download the codec you need from the link above, restart oCam, and apply the codec you want.
