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:

Setting the Codec - Selecting an External Video Codec (VFW)
oCam is a simple and intuitive screen recording program that offers a user-friendly interface and a wide range of features, making it a useful tool for everyone from beginners to IT professionals. In particular, oCam supports a variety of codecs so users can record with the quality and settings they want. Among them, using external VFW (Video for Windows) codecs such as x264vfw or Xvid allows for a more flexible recording environment. Below is a detailed explanation of how to set up and use external codecs in oCam.
How to Set Up an External Codec
To use an external codec in oCam, you first need to go to the program's codec settings menu. On the main screen of oCam, click the Codec menu located at the top or in the settings menu, and a pop-up window related to codec selection will appear. This pop-up window provides options for choosing built-in codecs and external codecs, and here you should select the external codec option. Please note that external codecs support only the AVI container format. This is because the AVI format has excellent compatibility with VFW-based codecs.
When you select the external codec option in the pop-up window, a new settings window will open. This window includes a checkbox labeled 'Use External Codec,' and you need to enable this checkbox to configure an external codec. After checking the box, click the combo box at the bottom of the window to display a list of VFW-based external codecs installed on your computer. For example, if codecs such as x264vfw or Xvid are installed, you can choose the one you want from this list. After selecting a codec, click the OK button to save the setting.
Recording with an External Codec
Once the codec setup is complete, the external codec you selected will be applied automatically when you start recording in oCam. The x264vfw codec provides a high compression ratio and excellent image quality, making it suitable for high-resolution video recording, while Xvid is useful in a variety of environments thanks to its relatively small file size and stable performance. You can choose the appropriate codec based on the type of content you want to record. For example, you can choose x264vfw for high-quality gameplay recording, or Xvid if you want to minimize file size.
The recorded video will be saved in AVI format, and the image quality and file size will vary depending on the characteristics of the selected codec. Therefore, when using an external codec, it is a good idea to check and optimize the codec settings in advance, such as bitrate and frame rate. Some codecs provide a separate settings window where you can adjust detailed options, so using that when needed can give you more satisfying results.
Disabling the External Codec
If you no longer want to use an external codec, you can easily revert the setting. Go back to the Codec menu in oCam, select the external codec option, and then clear the 'Use External Codec' checkbox. Once the checkbox is cleared, oCam will automatically switch back to the built-in codec that was previously in use. Built-in codecs are generally easier to configure and are suitable for users who do not want more complex settings. Even after switching back to a built-in codec, recording quality remains stable, and you can still get optimized results based on oCam's default settings.
Advantages and Precautions When Using External Codecs
The biggest advantage of using external codecs is that you can fine-tune image quality and file size exactly the way you want. In particular, codecs such as x264vfw can save high-quality video in relatively small file sizes, which is a major benefit for users working with high-spec content. On the other hand, the relevant codec must be installed on your computer, and some codecs can consume a large amount of system resources, so your hardware specifications should be taken into account. Also, due to the nature of the AVI container, compatibility may be more limited than with other formats such as MP4, so it is worth keeping this in mind if you plan to edit or share the recorded video afterward.
