First off, I know the keyboard shortcut Ctrl-S to save.
What I am proposing would be a standard toolbar icon in editing (word processing, graphic, etc) programs, perhaps a hand holding a little floppy (which no one uses anymore) or something that allowed a user to drag a document back into a folder
to save it the same way that you can drag from a file manager into many programs.
This would not necessarily be used when only one copy is needed, but in my situation I have to have to regularly save three folders, all of which I generally have open on my desktop because I have to access them regularly: a folder on my local machine (for backup), a folder on the company server and often another folder for my editor.
With the outward bound drag and drop icon I could select the document and drag it back into these folders.
This icon could also allow for partial selection, with customizable numbering conventions so that an open document, midi, or image could have separate elements selected and saved.
If I am uploading an application skin and want to show users what each window looks like, I usually have to hit print screen and “copy-to” a bunch of times. Not with D&D save. With word documents I often have to save snippets (items cut from a story that may have to be reinserted) in various annoying ways (some Mac programs allow for scraps, but not my pc). Making your own crappy techno song and want to upload a sample of it? D&D save.
Maybe you could also drag to shortcuts on your desktop to upload to your website, to e-mail or whatever.
I could find nothing describing the situation I wanted, as a standard feature for multiple programs, online. I am sorry if I missed it.
