.SH NAME
syncthing-config \- Syncthing Configuration
.SH SYNOPSIS
.INDENT 0.0
.INDENT 3.5
.sp
.EX
$XDG_STATE_HOME/syncthing
$HOME/.local/state/syncthing
$HOME/Library/Application Support/Syncthing
%LOCALAPPDATA%\eSyncthing

.UNINDENT
.UNINDENT
.SH DESCRIPTION
.sp
Changed in version 1.27.0: The default location of the configuration and database directory on
Unix\-like systems was changed to \fB$XDG_STATE_HOME/syncthing\fP or
\fB$HOME/.local/state/syncthing\fP\&. Previously the default config location
was \fB$XDG_CONFIG_HOME/syncthing\fP or \fB$HOME/.config/syncthing\fP\&. The
database directory was previously \fB$HOME/.config/syncthing\fP or, if the
environment variable was set, \fB$XDG_DATA_HOME/syncthing\fP\&. Existing
installations may still use these directories instead of the newer
defaults.
.sp
Added in version 1.5.0: Database and config can now be set separately. Previously the database was
always located in the same directory as the config.
.sp
Syncthing uses a single directory to store configuration and crypto keys.
Syncthing also keeps an index database with file metadata which is by
default stored in the same directory, though this can be overridden.
.sp
The location defaults to \fB$XDG_STATE_HOME/syncthing\fP or
\fB$HOME/.local/state/syncthing\fP (Unix\-like), \fB$HOME/Library/Application
Support/Syncthing\fP (Mac), or \fB%LOCALAPPDATA%\eSyncthing\fP (Windows). It can
be changed at runtime using the \fB\-\-config\fP or \fB\-\-home\fP flags or the
corresponding environment variables (\fB$STCONFDIR\fP or \fBSTHOMEDIR\fP). The
following files are located in this directory:
.INDENT 0.0
.TP
.B \fBconfig.xml\fP
The configuration file, in XML format.
.TP
.B \fBcert.pem\fP, \fBkey.pem\fP
The device’s ECDSA public and private key. These form the basis for the
device ID. The key must be kept private.
.TP
.B \fBhttps\-cert.pem\fP, \fBhttps\-key.pem\fP
The certificate and key for HTTPS GUI connections. These may be replaced
with a custom certificate for HTTPS as desired.
.UNINDENT
.sp
The database is by default stored in the same directory as the config, but
the location may be overridden by the \fB\-\-data\fP or \fB\-\-home\fP flags or the
corresponding environment variables (\fB$STDATADIR\fP or \fBSTHOMEDIR\fP).
.sp
The database directory contains the following files, among others:
.INDENT 0.0
.TP
.B \fBindex\-\fP\fI*\fP\fB\&.db\fP
A directory holding the database with metadata and hashes of the files
currently on disk and available from peers.
.TP
.B \fBsyncthing.log\fP
Log output, on some systems.
.TP
.B \fBaudit\-\fP\fI*\fP\fB\&.log\fP
Audit log data, when enabled.
.TP
.B \fBpanic\-\fP\fI*\fP\fB\&.log\fP
Crash log data, when required.
.UNINDENT
.SH CONFIG FILE FORMAT
.sp
The following shows an example of a default configuration file (IDs will differ):
.sp
\fBNOTE:\fP
.INDENT 0.0
.INDENT 3.5
The config examples are present for illustration. Do \fBnot\fP copy them
entirely to use as your config. They are likely out\-of\-date and the values
may no longer correspond to the defaults.

One or more \fBfolder\fP elements must be present in the file. Each element
describes one folder. The following attributes may be set on the \fBfolder\fP
element:
.INDENT 0.0
.TP
.B id (mandatory)
The folder ID, which must be unique.
.UNINDENT
.INDENT 0.0
.TP
.B label
The label of a folder is a human readable and descriptive local name. May
be different on each device, empty, and/or identical to other folder
labels. (optional)
.UNINDENT
.INDENT 0.0
.TP
.B filesystemType
The internal file system implementation used to access this folder, detailed
in a \fI\%separate chapter\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B path (mandatory)
The path to the directory where the folder is stored on this
device; not sent to other devices.
.UNINDENT
.INDENT 0.0
.TP
.B type
Controls how the folder is handled by Syncthing. Possible values are:
.INDENT 7.0
.TP
.B \fBsendreceive\fP
The folder is in default mode. Sending local and accepting remote changes.
Note that this type was previously called “readwrite” which is deprecated
but still accepted in incoming configs.
.TP
.B \fBsendonly\fP
The folder is in “send only” mode – it will not be modified by
Syncthing on this device.
Note that this type was previously called “readonly” which is deprecated
but still accepted in incoming configs.
.TP
.B \fBreceiveonly\fP
The folder is in “receive only” mode – it will not propagate
changes to other devices.
.TP
.B \fBreceiveencrypted\fP
Must be used on untrusted devices, where the data cannot be decrypted
because no folder password was entered. See \fI\%Untrusted (Encrypted) Devices\fP\&.
.UNINDENT
.UNINDENT
.INDENT 0.0
.TP
.B rescanIntervalS
The rescan interval, in seconds. Can be set to \fB0\fP to disable when external
plugins are used to trigger rescans.
.UNINDENT
.INDENT 0.0
.TP
.B fsWatcherEnabled
If set to \fBtrue\fP, this detects changes to files in the folder and scans them.
.UNINDENT
.INDENT 0.0
.TP
.B fsWatcherDelayS
The duration during which changes detected are accumulated, before a scan is
scheduled (only takes effect if \fI\%fsWatcherEnabled\fP is set to \fBtrue\fP).
.UNINDENT
.INDENT 0.0

The maximum delay before a scan is triggered when a file is continuously
changing. If unset or zero a default value is calculated based on
\fI\%fsWatcherDelayS\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B ignorePerms
If \fBtrue\fP, files originating from this folder will be announced to remote
devices with the “no permission bits” flag. The remote devices will use
whatever their default permission setting is when creating the files. The
primary use case is for file systems that do not support permissions, such
as FAT, or environments where changing permissions is impossible.
.UNINDENT
.INDENT 0.0
.TP
.B autoNormalize
Automatically correct UTF\-8 normalization errors found in file names. The
mechanism and how to set it up is described in a \fI\%separate chapter\fP\&.
.UNINDENT
.sp
The following child elements may exist:
.INDENT 0.0
.TP
.B device
These must have the \fBid\fP attribute and can have an \fBintroducedBy\fP
attribute, identifying the device that introduced us to share this folder
with the given device. If the original introducer unshares this folder with
this device, our device will follow and unshare the folder (subject to
\fI\%skipIntroductionRemovals\fP being \fBfalse\fP on the introducer device).
.sp
All mentioned devices are those that will be sharing the folder in question.
Each mentioned device must have a separate \fBdevice\fP element later in the file.
It is customary that the local device ID is included in all folders.
Syncthing will currently add this automatically if it is not present in
the configuration file.
.sp
The \fBencryptionPassword\fP sub\-element contains the secret needed to decrypt
this folder’s data on the remote device. If left empty, the data is plainly
accessible (but still protected by the transport encryption). The mechanism
and how to set it up is described in a \fI\%separate chapter\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B minDiskFree
The minimum required free space that should be available on the disk this
folder resides. The folder will be stopped when the value drops below the
threshold. The element content is interpreted according to the given
\fBunit\fP attribute. Accepted \fBunit\fP values are \fB%\fP (percent of the disk
/ volume size), \fBkB\fP, \fBMB\fP, \fBGB\fP and \fBTB\fP\&. Set to zero to disable.
.UNINDENT

advanced users only; do not change unless requested to or you’ve actually
read and understood the code yourself. :)
.UNINDENT
.INDENT 0.0
.TP
.B pullerMaxPendingKiB
Controls when we stop sending requests to other devices once we’ve got this
much unserved requests. The number of pullers is automatically adjusted
based on this desired amount of outstanding request data.
.UNINDENT
.INDENT 0.0
.TP
.B order
The order in which needed files should be pulled from the cluster. It has
no effect when the folder type is “send only”. The possibles values are:
.INDENT 7.0
.TP
.B \fBrandom\fP (default)
Pull files in random order. This optimizes for balancing resources among
the devices in a cluster.
.TP
.B \fBalphabetic\fP
Pull files ordered by file name alphabetically.
.TP
.B \fBsmallestFirst\fP, \fBlargestFirst\fP
Pull files ordered by file size; smallest and largest first respectively.
.TP
.B \fBoldestFirst\fP, \fBnewestFirst\fP
Pull files ordered by modification time; oldest and newest first
respectively.
.UNINDENT
.sp
Note that the scanned files are sent in batches and the sorting is applied
only to the already discovered files. This means the sync might start with
a 1 GB file even if there is 1 KB file available on the source device until
the 1 KB becomes known to the pulling device.
.UNINDENT
.INDENT 0.0
.TP
.B ignoreDelete
.
\fBWARNING:\fP
.INDENT 7.0
.INDENT 3.5
Enabling this is highly discouraged \- use at your own risk. You have been warned.
.UNINDENT
.UNINDENT
.sp
When set to \fBtrue\fP, this device will pretend not to see instructions to
delete files from other devices. The mechanism is described in a
\fI\%separate chapter\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B scanProgressIntervalS
The interval in seconds with which scan progress information is sent to the GUI. Setting to \fB0\fP
will cause Syncthing to use the default value of two.
.UNINDENT
.INDENT 0.0
.TP
.B pullerPauseS
Tweak for rate limiting the puller when it retries pulling files. Don’t
change this unless you know what you’re doing.
.UNINDENT
.INDENT 0.0
.TP
.B maxConflicts
The maximum number of conflict copies to keep around for any given file.
The default, \fB\-1\fP, means an unlimited number. Setting this to \fB0\fP disables
conflict copies altogether.
.UNINDENT
.INDENT 0.0
.TP
.B disableSparseFiles
By default, blocks containing all zeros are not written, causing files
to be sparse on filesystems that support this feature. When set to \fBtrue\fP,
sparse files will not be created.
.UNINDENT
.INDENT 0.0
.TP
.B disableTempIndexes
By default, devices exchange information about blocks available in
transfers that are still in progress, which allows other devices to
download parts of files that are not yet fully downloaded on your own
device, essentially making transfers more torrent like. When set to
\fBtrue\fP, such information is not exchanged for this folder.
.UNINDENT
.INDENT 0.0
.TP
.B paused
True if this folder is (temporarily) suspended.
.UNINDENT
.INDENT 0.0
.TP
.B weakHashThresholdPct
Use weak hash if more than the given percentage of the file has changed. Set
to \fB\-1\fP to always use weak hash. Default is \fB25\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B markerName
Name of a directory or file in the folder root to be used as
\fI\%How do I serve a folder from a read only filesystem?\fP\&. Default is \fB\&.stfolder\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B copyOwnershipFromParent
On Unix systems, tries to copy file/folder ownership from the parent directory (the directory it’s located in).
Requires running Syncthing as a privileged user, or granting it additional capabilities (e.g. CAP_CHOWN on Linux).
.UNINDENT
.INDENT 0.0
.TP
.B modTimeWindowS
Allowed modification timestamp difference when comparing files for
equivalence. To be used on file systems which have unstable
modification timestamps that might change after being recorded
during the last write operation. Default is \fB2\fP on Android when the
folder is located on a FAT partition, and \fB0\fP otherwise.
.UNINDENT
.INDENT 0.0
.TP
.B maxConcurrentWrites
Maximum number of concurrent write operations while syncing. Increasing this might increase or
decrease disk performance, depending on the underlying storage. Default is \fB2\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B disableFsync
.
\fBWARNING:\fP
.INDENT 7.0
.INDENT 3.5
This is a known insecure option \- use at your own risk.
.UNINDENT
.UNINDENT
.sp
Disables committing file operations to disk before recording them in the
database. Disabling fsync can lead to data corruption. The mechanism is
described in a \fI\%separate chapter\fP\&.
.UNINDENT
.INDENT 0.0
.TP
.B blockPullOrder
Order in which the blocks of a file are downloaded. This option controls how quickly different parts of the
file spread between the connected devices, at the cost of causing strain on the storage.
.sp
Available options:
.INDENT 7.0
.TP
.B \fBstandard\fP (default)
The blocks of a file are split into N equal continuous sequences, where N is the number of connected
devices. Each device starts downloading its own sequence, after which it picks other devices
sequences at random. Provides acceptable data distribution and minimal spinning disk strain.
.TP
.B \fBrandom\fP
The blocks of a file are downloaded in a random order. Provides great data distribution, but very taxing on
spinning disk drives.
.TP
.B \fBinOrder\fP
The blocks of a file are downloaded sequentially, from start to finish. Spinning disk drive friendly, but provides
no improvements to data distribution.
.UNINDENT
.UNINDENT
.INDENT 0.0
.TP
.B copyRangeMethod
Provides a choice of method for copying data between files. This can be
used to optimise copies on network filesystems, improve speed of large
copies or clone the data using copy\-on\-write functionality if the underlying
filesystem supports it. The mechanism is described in a \fI\%separate
chapter\fP\&.
.UNINDENT

.TP
.B address (mandatory: At least one must be present.)
Contains an address or host name to use when attempting to connect to this device.
Entries other than \fBdynamic\fP need a protocol specific prefix. For the TCP protocol
the prefixes \fBtcp://\fP (dual\-stack), \fBtcp4://\fP (IPv4 only) or \fBtcp6://\fP (IPv6 only) can be used.
The prefixes for the QUIC protocol are analogous: \fBquic://\fP, \fBquic4://\fP and \fBquic6://\fP
Note that IP addresses need not use IPv4 or IPv6 prefixes; these are optional. Accepted formats are:
.INDENT 7.0
