Re: .lyx~ backup-files: to delete? OK, but …

[Joachim Osnabryg]

I regard it necessary that the LyX user must be enlightened about the possible functions of the .lyx~ backup files and how to handle with it in the "Tools > Preferences > Look & Feel > User interface" pane!

Still I do not really know what the backup file is for… Sure one could use it to go back to the state of the LyX file when opend again for continued editing in one step, i. e. without going back step-by-step with edit=>backward (germ. "rückgängig") = Ctrl + <-. But nowwhere is described how to accomplish this. The files.lyx~ cannot be opened in the normal way by LyX, only with the trick: rightclick one in Finder/File manager -> open with -> all programs -> lyx.app (so on Mac). Finally, in the 4th and 5th checkboxes of the "Tools > Preferences > Look & Feel > User interface" menu is not transparent, that the checking of box  "Backup original documents when saving" is the _condition_ for the eventual checked and specified box  "Backup documents, every XX minutes." From the logical structure of this options' window I concluded the two possibilities would be alternative (and/or additional). Still uncertain, wether the .lyx~ backup files have yet another scope within the LyX.app … joachim -- Mac BacicTeX 2009 - TeXShop 2.29 / TeXworks 0.2.3 LyX 1.6.5 - MacBook Pro intel OSX 10.4.11 Tiger
