Removes a file or empty directory.

Function

Synopsis

success = love.filesystem.remove( name )

Arguments

string name
The file or directory to remove.

Returns

boolean success
True if the file/directory was removed, false otherwise.

Notes

The directory must be empty before removal or else it will fail. Simply remove all files and folders in the directory beforehand.

If the file exists in the .love but not in the save directory, it returns false as well.

An opened File prevents removal of the underlying file. Simply close the File to remove it.

Examples

Create a bunch of folders in the save folder and remove them and any file they may contain as soon as the game is quit.

function love.load()
    local dir = 'a'
    for _ = 1, 10 do
        dir = dir .. '/a'
    end
    love.filesystem.createDirectory( dir )
end

function love.quit()
    local function recursivelyDelete( item )
        if love.filesystem.getInfo( item , "directory" ) then
            for _, child in pairs( love.filesystem.getDirectoryItems( item )) do
                recursivelyDelete( item .. '/' .. child )
                love.filesystem.remove( item .. '/' .. child )
            end
        elseif love.filesystem.getInfo( item ) then
            love.filesystem.remove( item )
        end
        love.filesystem.remove( item )
    end
    recursivelyDelete( 'a' )
end
