Hide Files FAQ Image

Here you can find a collection of the most frequently asked questions about Vovsoft Hide Files software.


I forgot my password. I get "wrong password" error message. How to recover my password?
  • Open "Hide Files" software. Click: "Forgot Password". A reminder email will be sent to your email address associated with your license key. It is not possible to send a password recovery email without a registered license key. The software must be activated.
  • How to Activate using License Key
How to enter or change my license key?
  • Right-click the Hide Files system tray icon, then click "Edit License", finally enter your license key.
How to change master password of "Hide Files"?
  • First, log into "Hide Files" using your current password. Then, use the menu on the top: Edit - Change Password.
Can other Windows user accounts run "Hide Files", lock/unlock files/folders?
  • Yes. All users can access "Hide Files" if they know the valid "Hide Files" password.
Does "Hide Files" provide military-grade encryption?
  • "Hide Files" makes data hidden, changes folder locations and renames files. In this way it provides essential protection.
  • Additionally you can enable "Content Encryption" using the menu. However content encryption is a slow (time-consuming) operation and usually irreversible if correct private key is lost. While we don't claim to provide military-grade security, you can secure your files in most cases using content encryption.
How does "Hide Files" really work?
  • "Hide Files" creates a special directory (VVSFTFLDRHD) and moves your files there. This hidden directory is created at the root of any required drive. Original filenames are saved in Windows Registry. Unencrypted files get .db extension while encrypted files get .dbx extension. The software uses standard cryptography utilizing SHA256 and PKCS7 algorithms. The software also splits large files into smaller (100 MB) pieces for encryption.
  • Recent versions of Hide Files creates a special backup directory (VVSFTFLDRBAK). With the help of the most recent BAK file in this folder, you can correctly rename .db files.
Can other computer users see my hidden files using Windows safe mode or command line?
  • No. The hidden files cannot be seen by other users without significant technical knowledge.
Can I lock my external disk in my computer and unlock it in another computer by installing "Hide Files" on both of the computers?
  • No. Locking and unlocking can only be performed on the same computer.

My computer crashed, i can't access my hidden files. What can I do to recover my files?
  • "Hide Files" keeps filenames and directory structure on Windows Registry. It can't unlock and restore files without proper Windows Registry entries. Fortunately "Hide Files" creates backups that can facilitate recovery. First of all, download and install the latest version of "Hide Files" from our web site. Then, launch the application and use the menu item: "Process" - "Recover Lost Files". Click the most recent backup filename on the list and try to recover your files.

    Recover Lost Files using Hide Files

    If this way doesn't solve the problem, please try recovering your files using recovery software such as DMDE, R-Studio, Disk GeniusHasleo Data Recovery, Deep Data Recovery, ZAR X, GetDataBack, EaseUS, PhotoRecRecuva. Ensure that you refrain from writing anything to that drive. Instead, store the retrieved contents onto a separate drive.

I'm concerned about the possibility of my computer experiencing a crash. How can I be able to recover my locked files after reinstalling Windows on C drive?
  1. Unlock any files on the C drive. Move and lock them inside another drive.
  2. "Hide Files" must be closed properly.
  3. Go to C:\Users\[USERNAME]\AppData\Roaming\VOVSOFT\Hide Files
  4. Copy the latest BAK file into another drive other than C.
    You can recover all your files, after formatting the C drive and reinstalling Windows, by using the BAK file.
I reinstalled Windows. I have my BAK file. How can I restore my locked files?
  1. Install "Hide Files" into your new system.
  2. Open menu item: "Process" - "Recover Lost Files".
  3. Browse your BAK file.
  4. Select the files you wish to recover or click "Select All".
  5. Click "Recover Selected Files".
My locked files/folders are not displayed on "Hide Files". What is wrong?
  • You must use the same Windows installation. If Windows was reinstalled or Windows Registry was cleared, "Hide Files" can not display and unlock the files/folders. If this is not your case, you can try Windows System Restore and restore to an old installation point.
I try to lock a file/folder but I get an error message. What can I do?
  • The files or folders you want to lock should not be used by another application or Windows service.
I try to unlock a file/folder but I get an error message. What can I do?
  • If you get "Drive mismatch" error; the file/folder you wish to unlock is probably on an external drive, make sure the drive is connected and the drive letter you locked before is the same, change the drive letter if it's necessary.
  • If you get "File already exists" error; use the menu Process -> Ignore Failed Files While Unlocking then try to unlock again.
  • Make sure the target file/folder is not used by another process.
  • You can also try to create the folders manually so that the software can restore the files. This error can occur if there is a user privilege problem in the folder.

I wish you would add a right-click menu in Windows Explorer. This way when I want to hide a file or folder I will just right-click my selected file/folder and then select Vovsoft Hide File to hide what I select. This is so much easier and faster than doing it your current way.....open program, find and then select files and folders to hide. This a not practical and slooooooow.

Hi I upgraded my windows to windows 10 while my files were hidden by Hide Files in the previous OS. I formatted Local Disk C and installed windows 10. Now, my files are still hidden. The local disks E and D show that they have files but they do not appear. I re installed Hide Files in the new windows but still the files do not appear. Please help!

My C-drive totally crashed, can't access at all. So I've lost: "C:\Program Files (x86)\VOVSOFT\Hide Files\hidefiles.exe" I reinstalled windows on new C-drive and installed hide-files and ran (using the PW I had saved elsewhere), but of course its "recovery" doesn't show any files to recover on other discs! Is there anything I can do?

Hello Robert. Our software relies on Windows Registry. If Windows installation in C drive is corrupted (and you don't have a registry backup BAK file), you should use a recovery software or get professional recovery service (we don't offer). If you reinstall Windows on this drive, this may reduce your chances of recovery.

I used VovSoft Hide Files software in my previous Windows. But when I changed my Windows, this software was deleted and access to the files I had locked became impossible. But the size of the rest of the drives indicates that those files have not been deleted yet. Is there a way I can find those files again?

I used VovSoft file hiding software on USB external hard drive. After changing the laptop window, I opened the VovSoft file hiding software in the USB external hard drive. However, the hidden folder on the USB external hard drive is not displayed in "Hide Files". The size of the USB external hard drive indicates that the file has not yet been deleted. Is there any way to get those files back?
