I’m not sure that I understand you correctly but - if what you’re seeing is ( for example ) sword.blend, then underneath it sword.blend1, sword.blend2, etc - what you are seeing is saved versions of your work. Blender automatically saves versions everytime you save your work - this can be controlled under the ‘autosave’ button in the hidden menu through the ‘save versions’ control.
I’m not too knowledgeable about packed files - but so far as I know as long as the file is opened in blender (as a .blend file would have to be) the file can be read in it’s entirety. Blender routinely packs files on it’s own - that’s what the little green box next to your files represents. If you click on “open” rather than “open recent” you should notice these. If the user does happen to have a problem reading the file all you need to do is click on “unpack into files” which is found underneath the pack option.
Hope this helps
