Here’s how i open the files and write to them. Should i nil them? Does it really matter?

 \_path = system.pathForFile( "test.txt", system.DocumentsDirectory ) \_file = io.open( \_path, "w" ) \_file:write( testIt ) io.close( \_file ) \_file = nil \_path = nil

No.

Also, define ‘safe’.

  • doesn’t free meaningful amount of memory

  • can’t access file after closed so not safer than closing
