The splf file stores some kind of data used by SecureZIP. The splf file extension is associated with the SecureZIP, a tool for Microsoft Windows, Mac and other operating systems that allows users to protect their sensitive data.If any parts are missing, you cannot combine the files. You must include all the pieces, which have the same name but a sequentially numbered extension. Drag all the split zip files into this folder. Choose the 'File' menu and select 'New' and 'Folder' to create a new folder, which you may optionally rename.
