Unit: Lazarus lclintf
function OpenURL(AURL: String): Boolean;
Official documentation: OpenUrl
Description
OpenUrl opens a URL with the default/registered/preferred web browser as specified by the operating system.
Spaces in URLs need to be encoded as %20; see RFC1738. When using the file:// URI scheme, you should not encode spaces with %20.
Warning
On Windows with Lazarus versions older than revision r40490 (2013-03-06), opening a URL using the file:// URI scheme (to open a local file) may fail if there are spaces in the filename.
With those older Lazarus versions, you should enclose the entire string in double quotation marks, if you are on an NT platform.
This is unfortunately system and browser dependant. Note: opening a file:// URL with spaces on Win9x will probably fail if you enclose the URL in quotation marks (See Issue #21659).
On Windows it is preferable to not use OpenUrl with the file:// URI scheme, but use OpenDocument with the filename instead because of the above mentioned problems.
