lays much stress on safety.
We know how much effort you invest in your work,
\SpecialChar LyX
might crash (although we put in all effort that it doesn't),
you might face a power outage while you are working on a document with unsaved changes,
- disks might get corrupt or files might get lost or damaged during synchronization.

For such cases,
\SpecialChar LyX
provides a multi-layered safety net that will hopefully prevent you from major hassles.

+\change_inserted -712698321 1676624410
+By default,
+ \SpecialChar LyX

+ These files normally are stored in the same directory than the original file and with the same file name but the extension
+\family typewriter

+\family default
+ (e.
+\begin_inset space \thinspace{}
+\end_inset
+
+g.,

+\family typewriter

+\family default

+ If you prefer to have all backups in a central place (and maybe on a separate disk),
+ you can specify a
+\family sans

+ then all backups are stored there.
+ In order to prevent file name clashes,
+ the files then do not simply have the original file name,
+ but also the path in their name,

+\end_layout

+\begin_layout Standard

+\end_layout

+\begin_layout Standard

+\change_inserted -712698321 1676624657

+
+\begin_inset CommandInset ref

+Emergency files
+\end_layout

+\begin_layout Standard
+
+\change_inserted -712698321 1676624951
+If \SpecialChar LyX
+ crashes and documents have unsaved changes,
+ the program furthermore tries to write an emergency file,
+ which is a version of the document containing all unsaved changes.
+\end_layout
+
+\begin_layout Standard

+\change_inserted -712698321 1676625158

+\family default
+ (e.
+\begin_inset space \thinspace{}
+\end_inset
+
+g.,
+
+\family typewriter
+myfile.lyx.emergency
+\family default
+).
+ When the respective document is reopened with \SpecialChar LyX
+ next time,
+ the application recognizes the emergency file and asks you whether it should try to recover your file to that last state.
+ If you agree,
+ it will do so,
+ and if this succeeds it will ask you next whether the emergency file can be deleted.
+ Agree on this only after you checked that everything has been correctly recovered!

+\change_inserted -712698321 1676625452
+If you open a \SpecialChar LyX
+ document for the first time with a new major version of \SpecialChar LyX
+,
+ it gets converted to the new file format (allowing for new features).
+ In such cases,
+ \SpecialChar LyX
+ keeps a copy of the old version,
+ named as
+\family typewriter
+<filename>-lyxformat-<n>.lyx
+\family default
+,
+ where <n> is the old format (e.
+\begin_inset space ~
+\end_inset
+
+g.,
+
+\family typewriter
+myfile-lyxformat-474.lyx
+\family default

+ Those files are stored at the same location than the backup files,

+ if specified,
+ in the backup directory.
+\end_layout

+When to Use Which File?
+\end_layout
+
+\begin_layout Standard
+
+\change_inserted -712698321 1676625539
+Now why all these files?
+ Because they have different purposes.
+ Generally spoken:
+\end_layout
+
+\begin_layout Standard
+
+\change_inserted -712698321 1676625820
+If \SpecialChar LyX
+ terminates unexpectedly,
+\end_layout
+
+\begin_layout Enumerate
+
+\change_inserted -712698321 1676625790
+first try to restore from the emergency file (by reopening the document in \SpecialChar LyX
+).
+ This file has the latest changes,
+ even changes you made after the last auto-save snapshot has been made.
+\end_layout
+
+\begin_layout Enumerate
+
+\change_inserted -712698321 1676626031
+If the rescue file way did not work because there is no rescue file (e.
+\begin_inset space \thinspace{}
+\end_inset
+
+g.,
+ after a power outage) or if the rescue file is damaged (it might happen in mean cases that the rescue files contains just that latest addition that makes \SpecialChar LyX
+ crash!),
+ look if there is an auto-save snapshot.
+ If so,
+ rename it (not to the original file name unless you checked it) and see if that works for you.
+ In the worst case (with the default setting at least),
+ you will have lost maximally 5 minutes of work.
+\end_layout
+
+\begin_layout Enumerate
+
+\change_inserted -712698321 1676626178
+If there is no auto-save snapshot or this one is garbled as well,
+ use the backup file.
+ It does not have all the unsaved changes,
+ but it might still be the most recent you can get.
+ This is particularly the case if the original file itself got lost or is damaged.
+\end_layout
+
+\begin_layout Standard
+
+\change_inserted -712698321 1676626301
+The fourth type of file,
+ the backup file from old versions,
+ is useful if the conversion process did not work and results in a non-working document (although we put in all efforts to prevent this) or if you mistakenly opened and saved a document with a newer version (such as a development version) and actually want to keep on using the old version.
+\end_layout

+\begin_layout Standard

+\change_inserted -712698321 1676626368
+So much for the safety net.
+ We hope you will not not it,
+ but if so,
+ that it catches you as high up as possible.
+ Now let us turn to the actual writing process.
