The location defaults to \fB$HOME/.config/syncthing\fP (Unix\-like), \fB$HOME/Library/Application Support/Syncthing\fP (Mac), \fB%AppData%/Syncthing\fP (Windows XP) or \fB%LocalAppData%/Syncthing\fP (Windows 7+). It can be changed at runtime using the \fB\-home\fP flag. In this directory the following files are located: .INDENT 0.0 .TP .B \fBconfig.xml\fP The configuration file, in XML format. .TP .B \fBcert.pem\fP, \fBkey.pem\fP The device\(aqs RSA 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. .TP .B \fBindex\-\fI*\fP\&.db\fP A directory holding the database with metadata and hashes of the files currently on disk and available from peers. .TP .B \fBcsrftokens.txt\fP A list of recently issued CSRF tokens (for protection against browser cross site request forgery). .UNINDENT .SH CONFIG FILE FORMAT .sp The following is shows the default configuration file: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C 0 0 0 random

.ft P .fi .UNINDENT .UNINDENT .SH CONFIGURATION ELEMENT .sp This is the root element. .INDENT 0.0 .TP .B version The config version. Increments whenever a change is made that requires migration from previous formats. .UNINDENT .SH FOLDER ELEMENT .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C 0 0 0 random .ft P .fi .UNINDENT .UNINDENT .sp 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 The folder ID, must be unique. (mandatory) .TP .B path The oath to the directory where the folder is stored on this device; not sent to other devices. (mandatory) .TP .B ro True if the folder is read only (Master mode; will not be modified by Syncthing) on this device. .TP .B rescanIntervalS The rescan interval, in seconds. .TP .B ignorePerms True if the folder should ignore permissions. .TP .B autoNormalize Automatically correct UTF\-8 normalization errors found in file names. .UNINDENT .sp The following child elements may exist: .INDENT 0.0 .TP .B device These must have the \fBid\fP attribute and nothing else. 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 repositories. Syncthing will currently add this automatically if it is not present in the configuration file. .TP .B versioning Specifies a versioning configuration. .sp \fBNOTE:\fP .INDENT 7.0 .INDENT 3.5 Needs explanation. .UNINDENT .UNINDENT .TP .B copiers, pullers, hashers The number of copier, puller and hasher routines to use, or zero for the system determined optimum. These are low level performance options for advanced users only; do not change unless requested to or you\(aqve actually read and understood the code yourself. :) .TP .B order The order in which needed files should be pulled from the cluster. The possibles values are: .INDENT 7.0 .TP .B random Pull files in random order. This optimizes for balancing resources among the devices in a cluster. .TP .B alphabetic Pull files ordered by file name alphabetically. .TP .B smallestFirst, largestFirst Pull files ordered by file size; smallest and largest first respectively. .TP .B oldestFirst, newestFirst Pull files ordered by modification time; oldest and newest first respectively. .UNINDENT .UNINDENT .SH DEVICE ELEMENT .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C

.ft P .fi .UNINDENT .UNINDENT .sp One or more \fBdevice\fP elements must be present in the file. Each element describes a device participating in the cluster. It is customary to include a \fBdevice\fP element for the local device; Syncthing will currently add one if it is not present. The following attributes may be set on the \fBdevice\fP element: .INDENT 0.0 .TP .B id The device ID. This must be written in canonical form, that is without any spaces or dashes. (mandatory) .TP .B name A friendly name for the device. (optional) .TP .B compression Whether to use protocol compression when sending messages to this device. The possible values are: .INDENT 7.0 .TP .B metadata Compress metadata packets, such as index information. Metadata is usually very compression friendly so this is a good default. .TP .B always Compress all packets, including file data. This is recommended if the folders contents are mainly compressible data such as documents or text files. .TP .B never Disable all compression. .UNINDENT .TP .B introducer Set to true if this device should be trusted as an introducer, i.e. we should copy their list of devices per folder when connecting. .UNINDENT .sp In addition, one or more \fBaddress\fP child elements must be present. Each contains an address to use when attempting to connect to this device and will be tried in order. Accepted formats are: .INDENT 0.0 .TP .B IPv4 address (\fB192.0.2.42\fP) The default port (22000) is used. .TP .B IPv4 address and port (\fB192.0.2.42:12345\fP) The address and port is used as given. .TP .B IPv6 address (\fB2001:db8::23:42\fP) The default port (22000) is used. .TP .B IPv6 address and port (\fB[2001:db8::23:42]:12345\fP) The address and port is used as given. The address must be enclosed in angled brackets. .TP .B \fBdynamic\fP The word \fBdynamic\fP means to use local and global discovery to find the device. .UNINDENT .SH GUI ELEMENT .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C

.ft P .fi .UNINDENT .UNINDENT .sp There must be exactly one \fBgui\fP element. The GUI configuration is also used by the rest\-api and the event\-api\&. The following attributes may be set on the \fBgui\fP element: .INDENT 0.0 .TP .B enabled If not \fBtrue\fP, the GUI and API will not be started. .TP .B tls If set to \fBtrue\fP, TLS (HTTPS) will be enforced. Non\-HTTPS requests will be redirected to HTTPS. When this is set to \fBfalse\fP, TLS connections are still possible but it is not mandatory. .UNINDENT .sp The following child elements may be present: .INDENT 0.0 .TP .B address Set the listen addresses. One or more address elements must be present. Allowed address formats are: .INDENT 7.0 .TP .B IPv4 address and port (\fB127.0.0.1:8384\fP) The address and port is used as given. .TP .B IPv6 address and port (\fB[::1]:8384\fP) The address and port is used as given. The address must be enclosed in angled brackets. .TP .B Wildcard and port (\fB0.0.0.0:12345\fP, \fB[::]:12345\fP, \fB:12345\fP) These are equivalent and will result in Syncthing listening on all interfaces and both IPv4 and IPv6. .UNINDENT .TP .B username Set to require authentication. .TP .B password Contains the bcrypt hash of the real password. .TP .B apikey If set, this is the API key that enables usage of the REST interface. .UNINDENT .SH OPTIONS ELEMENT .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C 0.0.0.0:56847 udp4://announce.syncthing.net:22026 udp6://announce\-v6.syncthing.net:22026 true true 21025 [ff32::5222]:21026 0 0 60 true true 60 30 10 0 true 12 24 true 5 true false 0 60 120 .ft P .fi .UNINDENT .UNINDENT .sp The \fBoptions\fP element contains all other global configuration options. .INDENT 0.0 .TP .B listenAddress The listen address for incoming sync connections.
