Frequently Asked Questions
How do I password protect a folder?
Select your folder using the FileLocker tool above, set a password, and click to protect. FileLocker packages all folder contents and encrypts them locally, saving a single .vault file.
Do I need to create a ZIP file first?
No. FileLocker handles the packaging automatically. When you select a folder, FileLocker streams all its contents through an encryption pipeline and produces a single .vault file, preserving your original folder structure.
Will my folder structure be preserved when I unlock?
Yes. When you unlock a .vault file created from a folder, FileLocker restores the original folder structure and all file names exactly as they were.
Is there a limit on how many files I can protect in a folder?
FileLocker processes folder contents using a streaming approach. The practical number of files depends on browser support, available storage, device resources, and the size and number of files in the folder.
