=== File sharing URIs ===
The ''fs'' module ''identifier'' consists of either ''chk'', ''sks'', ''ksk'' or ''loc'' followed by a slash and a category specific value. Most URIs contain hashes, which are encoded in [[base32#base32hex|base32hex]].<ref>{{cite web|last1=Grothoff|first1=Christian|title=File-Sharing URIs|url=https://www.gnunet.org/fs-urisyntax|website=www.gnunet.org|access-date=15 July 2016|archive-date=17 August 2016|archive-url=https://web.archive.org/web/20160817025026/https://www.gnunet.org/fs-urisyntax|url-status=dead}}</ref>

* ''chk'' identifies files, typically: <code><nowiki>gnunet://fs/chk/[file hash].[query hash].[file size in bytes]</nowiki></code>
: File hash is the hash of the plaintext file, which allows decrypting it once it is downloaded. Query hash is the hash of topmost GBlock which allows downloading the whole tree of GBlocks that contain encrypted file. File size is required to determine the shape of the tree.
* ''sks'' identifies files within namespaces, typically: <code><nowiki>gnunet://fs/sks/NAMESPACE/IDENTIFIER</nowiki></code>
* ''ksk'' identifies search queries, typically: <code><nowiki>gnunet://fs/ksk/KEYWORD[+KEYWORD]*</nowiki></code>
* ''loc'' identifies a datum on a specific machine, typically: <code><nowiki>gnunet://fs/loc/PEER/QUERY.TYPE.KEY.SIZE</nowiki></code>

==== Examples ====
A type of GNUnet filesharing URI pointing to a specific copy of [[GNU GPL]] license text:
<code style="word-wrap:break-word">
gnunet://fs/chk/9E4MDN4VULE8KJG6U1C8FKH5HA8C5CHSJTILRTTPGK8MJ6VHORERHE68JU8Q0FDTOH1DGLUJ3NLE99N0ML0N9PIBAGKG7MNPBTT6UKG.1I823C58O3LKS24LLI9KB384LH82LGF9GUQRJHACCUINSCQH36SI4NF88CMAET3T3BHI93D4S0M5CC6MVDL1K8GFKVBN69Q6T307U6O.17992</code>

Another type of GNUnet filesharing URI, pointing to the search results of a search with keyword "gpl":
<code style="word-wrap:break-word">
gnunet://fs/ksk/gpl
