+# NAME
+
+CURLOPT_MAXFILESIZE - maximum file size allowed to download
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXFILESIZE, long size);
+~~~
+
+# DESCRIPTION
+
+Pass a long as parameter. This specifies the maximum accepted *size* (in
+bytes) of a file to download. If the file requested is found larger than this
+value, the transfer is aborted and *CURLE_FILESIZE_EXCEEDED* is returned.
+Passing a zero *size* disables this, and passing a negative *size* yields a
+*CURLE_BAD_FUNCTION_ARGUMENT*.
+
+The file size is not always known prior to the download start, and for such
+transfers this option has no effect - even if the file transfer eventually
+ends up being larger than this given limit.
+
+If you want a limit above 2GB, use CURLOPT_MAXFILESIZE_LARGE(3).
+
+Since 8.4.0, this option also stops ongoing transfers if they reach this
+threshold.
+
+# DEFAULT
+
+0, meaning disabled.
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode ret;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+    /* refuse to download if larger than 1000 bytes */
+    curl_easy_setopt(curl, CURLOPT_MAXFILESIZE, 1000L);
+    ret = curl_easy_perform(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
