                            <comment id="1691348" author="rstam" created="Fri, 6 Oct 2017 13:44:28 +0000"  >&lt;p&gt;The GridFS API lets you provide custom metadata when the file is first uploaded. But the GridFS API does not provide any way to update the metadata after the file has been uploaded.&lt;/p&gt;

&lt;p&gt;However, the metadata is stored in the &lt;tt&gt;fs.files&lt;/tt&gt; collection (note: replace &lt;tt&gt;fs&lt;/tt&gt; with your bucket name if you used a custom bucket name), which is a collection like any other. The contents of the &lt;tt&gt;fs.files&lt;/tt&gt; collection are described in the definition of &quot;Files collection document&quot; here:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://github.com/mongodb/specifications/blob/master/source/gridfs/gridfs-spec.rst#terms&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/specifications/blob/master/source/gridfs/gridfs-spec.rst#terms&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;As long as you are careful not to disturb the other fields you can update the metadata directly using a regular update statement.&lt;/p&gt;

&lt;p&gt;Something like this:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;

			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;var update = Builders&amp;lt;BsonDocument&amp;gt;.Update.Set(&quot;metadata&quot;, metadata);&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;filesCollection.UpdateOne(filter, update);&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
