 # Introduction
 DroidFS relies on modified versions of the original encrypted filesystems programs to open volumes. [CryFS](https://github.com/cryfs/cryfs) is written in C++ while [gocryptfs](https://github.com/rfjakob/gocryptfs) is written in [Go](https://golang.org). Thus, building DroidFS requires the compilation of native code. However, for the sake of simplicity, the application has been designed in a modular way: you can build a version of DroidFS that supports both Gocryptfs and CryFS, or only one of the two.
 
-Moreover, DroidFS aims to be accessible to as many people as possible. If you encounter any problems or need help with the build, feel free to open an issue, a discussion, or contact me by [email](mailto:hardcore.sushi@disroot.org) or on [Matrix](https://matrix.org): @hardcoresushi:matrix.underworld.fr

This require Android v6.0+. If your device is not encrypted, extracting the encryption key with physical access may be possible.</li>
-  </li>
+  <li><b>Disable volume auto-locking:</b> (previously called <i>"Keep volumes open when the app goes in background"</i>)

-  </li>
+  <li><b>Keep volumes open:</b>
-  <li><h4>Allow saving password hash using fingerprint:</h4>
+  (Different from the old <i>"Keep volumes open when the app goes in background"</i>. Yes it's confusing, sorry)

This require Android v6.0+. If your device is not encrypted, extracting the encryption key with physical access may be possible.
+
-  </li>
+  Keep the app running as a [foreground service](https://developer.android.com/develop/background-work/services/foreground-services) to maintain volumes open, even when the app is removed from recent tasks.
+
+  This avoid the app from being killed by the system during file operations or while accessing exposed volumes, but this mean cryptographic secrets stay in memory for an undefined amount of time.</li>

+
+  Decrypt and open file using external apps. These apps could save and send the files thus opened.</li>
+  <li><b>Expose open volumes⁽¹⁾:</b>
+
+  Allow open volumes to be browsed in the system file explorer (<a href="https://developer.android.com/guide/topics/providers/document-provider">DocumentProvider</a> API). Encrypted files can then be selected from other applications, potentially with permanent access. This feature requires <i>"Disable volume auto-locking"</i>, and works more reliably when <i>"Keep volumes open"</i> is also enabled.</li>
+  <li><b>Grant write access:</b>
+
+  Files opened with another applications can be modified by them. This applies to both previous unsafe features.</li>
 </ul>
-* Features requiring temporary writing of the plain file to disk (DroidFS internal storage). This file could be read by apps with root access or by physical access if your device is not encrypted.
+
+⁽¹⁾: These features can work in two ways: temporarily writing the plain file to disk (DroidFS internal storage) or sharing it via memory. By default, DroidFS will choose to keep the file only in memory as it's more secure, but will fallback to disk export if the file is too large to be held in memory. This behavior can be changed with the *"Export method"* parameter in the settings. Please note that some applications require the file to be stored on disk, and therefore do not work with memory-exported files.

 # Limitations
-DroidFS works as a wrapper around modified versions of the original encrypted container implementations ([libgocryptfs](https://forge.chapril.org/hardcoresushi/libgocryptfs) and [libcryfs](https://forge.chapril.org/hardcoresushi/libcryfs)). These programs were designed to run on standard x86 Linux systems: they access the underlying file system with file paths and syscalls. However, on Android, you can't access files from other applications using file paths. Instead, one has to use the [ContentProvider](https://developer.android.com/guide/topics/providers/content-providers) API. Obviously, neither Gocryptfs nor CryFS support this API. As a result, DroidFS cannot open volumes provided by other applications (such as cloud storage clients), nor can it allow other applications to access encrypted volumes once opened.

As a result, DroidFS cannot open volumes provided by other applications (such as cloud storage clients). If you want to synchronize your volumes on a cloud, the cloud application must synchronize the encrypted directory from disk.
 
 Due to Android's storage restrictions, encrypted volumes located on SD cards must be placed under `/Android/data/sushi.hardcore.droidfs/` if you want DroidFS to be able to modify them.
