I have problem in getting the size of the file using Lua. I am creating a function method that if the file size of the file is 743 bytes
, then the file will be deleted.
Here is my code :
local getDLFile = function(fileToDL)
local path = system.pathForFile(fileToDL, system.DocumentsDirectory )
local myFile = io.open( path, "w+b" )
http.request{
url = "http://www.testfile.com/"..fileToDL,
sink = ltn12.sink.file(myFile),
}
-- i don't know what is the syntax
if myFile.size == 743 bytes then
myFile.delete
end
end
Can anyone can help me about my case?
The size is given by myFile:seek("end")
.
To delete the file, use os.remove(path)
. But close the file first.
