In some programs, you can select and right click on a document and select a shred or secure erase kind of option to completely eliminate the document and any trace of the document. Is there an option to do so with a Libre Office document? Thxs!
No. This is a job better suited for your operating system utilities. Whether you are on Linux, Windows, or OSX, shredding a file is easy (for example, in linux or osx you can use the “srm” command to do it).
