Portable mode is a mode of file encryption (FLE) on removable drives that provides the ability to access data outside of a corporate network. Portable mode also lets you work with encrypted data on computers that do not have Kaspersky Endpoint Security installed.
Portable mode is convenient to use in the following cases:
Portable File Manager
To work in portable mode, Kaspersky Endpoint Security installs a special encryption module named Portable File Manager on a removable drive. The Portable File Manager provides an interface for working with encrypted data if Kaspersky Endpoint Security is not installed on the computer (see the figure below). If Kaspersky Endpoint Security is installed on your computer, you can work with encrypted removable drives using your usual file manager (for example, Explorer).
The Portable File Manager stores a key to encrypt files on a removable drive. The key is encrypted with the user password. The user sets a password before encrypting files on a removable drive.
The Portable File Manager starts automatically when a removable drive is connected to a computer on which Kaspersky Endpoint Security is not installed. If automatic startup of applications is disabled on the computer, manually start the Portable File Manager. To do so, run the file named pmv.exe that is stored on the removable drive.

Support for portable mode for working with encrypted files
Kaspersky Endpoint Security will encrypt files on the removable drive. The Portable File Manager used for working with encrypted files will also be added to the removable drive. If there are already encrypted files on the removable drive, Kaspersky Endpoint Security will encrypt them again using its own key. This allows the user to access all files on the removable drive in portable mode.
Accessing encrypted files on a removable drive
After encrypting files on a removable drive with portable mode support, the following file access methods are available:

Recovering the password for working in portable mode
If you have forgotten the password for working in portable mode, you need to connect the removable drive to a computer with Kaspersky Endpoint Security installed inside the corporate network. You will get access to the files because the secret key is stored in the computer's key storage or on the Administration Server. Decrypt and re-encrypt files with a new password.
Features of portable mode when connecting a removable drive to a computer from another network
If the computer is located outside the corporate network and Kaspersky Endpoint Security is installed on the computer, you can access the files in the following ways:
After entering the password, you will be able to view, modify, and save files on the removable drive (transparent access). Kaspersky Endpoint Security can set a read-only access right for a removable drive if the following parameters are configured in the policy settings for encryption of removable drives:
In all other cases, you will get full access to the removable drive (read/write permission). You will be able to add and delete files.
You can change the removable drive access permissions even while the removable drive is connected to the computer. If the removable drive access permissions are changed, Kaspersky Endpoint Security will block access to the files and prompt you for the password again.
After entering the password, you cannot apply encryption policy settings for the removable drive. In this case, it is impossible to decrypt or re-encrypt files on the removable drive.
If you have forgotten the password for working in portable mode, ask the administrator for access to files. To access the files, the user needs to send the administrator a request access file (a file with the KESDC extension). The user can send the request access file by email, for example. The administrator will send an encrypted data access file (a file with the KESDR extension).
After you complete the Request-Response password recovery procedure, you will receive transparent access to files on the removable drive, and full access to the removable drive (read/write permission).
You can apply a removable drive encryption policy, and decrypt files, for example. After recovering the password or when the policy is updated, Kaspersky Endpoint Security will prompt you to confirm the changes.
