Let’s deal with this in two pieces. Apologies if the following is undiplomatic or unprofessional. (To be clear, I do not work for Literature & Latte. I did do PC/network deployment and support for over twenty years, before retiring. You may detect a touch of burnout and crankiness in the following.)
IMPORTING FROM ANOTHER SCRIVENER PROJECT
I can partially recreate what you may have encountered, if you attempted to do the import via File > Import > Files and browsed into another project’s .scriv/files/docs subfolder and selected the .rtf files located there. Specifically, those files importing with numeric names (these are the correct physical names they actually have down in the source project folder system).
But their text comes in and subsequently moving them to Trash within the receiving project and then emptying Trash does not result in deletion of the original source .rtf files in the source project.
File > Import > Files is probably more appropriate for importing files produced by other apps, not folders and files produced by Scrivener.
In addition to the procedure suggested by nemesishaven, two ways probably more appropriate for bringing in material from another Scrivener project, which will retain meaningful folder/item names and such:
- File > Import > Scrivener Project and browsing to and selecting/opening that project’s .scriv folder (not files down inside it… Scrivener handles that).
- Open both the target and source projects in Scrivener, place the two Scrivener instances next to each other and drag and drop binder folders/items from one project to the other.
Try one or both of those and see how that works.
As far as Scrivener deleting source files over in another project… theoretically possible, but very very unlikely. There’s no reason deleting, particularly without prompted knowledge and approval of the user, would be coded in an import. And that is something that has rarely if ever been reported in the forums. You most likely ran into or unintentionally did something else, but didn’t realize it.
A Scrivener project is a database implemented as a folder (name ending in .scriv) containing multiple subfolders and files at the Windows file system level. The logical/conceptual view that one sees within Scrivener differs, of necessity, from the underlying implementation in the Windows file system. Best to deal with them at the project level from within Scrivener rather than getting down inside the project folder via Windows File Explorer, other than for the purposes of launching a project from Windows (rather than from inside Scrivener) by clicking on the project index file (name ends in .scrivx). (The same holds true for the Mac version, except that the Mac OS hides the contents of the project folder and presents it as a single object, unless one goes out of their way to instruct it to show the contents.) If copying or backing up out in Windows, rather than from inside Scrivener, deal with it as a whole (the .scriv project folder), rather than subfolders and files down inside the project folder.
Scrivener is not Word. Like Word, or any other app, it has a learning curve. It may resonate with and work for you, it may not. This is best determined during the free trial period, rather than after purchase.
WORRISOME POSTINGS BY OTHERS
As with other apps out there from other vendors, the majority of folks using Scrivener are out there using the app without major issues.
You are seeing what tech support folks routinely encounter regardless of app or vendor… snap diagnoses and leaps to judgement and frustration and self righteous accusation by a minority of both inexperienced and experienced users that, while constituting a starting point, often prove to be incorrect or incomplete, and often fail to account for issues outside of Scrivener and Scrivener’s control… such as certain problematic antivirus apps and inadequate or incorrect procedures when dealing with assuring backups, unreliable external storage, storing projects on Internet cloud storage, etc.
Skim support forums for most any popular app and you’ll see similar.
Deal with just the issue you encountered. You might email tech support directly, per literatureandlatte.com/support.php#section-email
Take other postings with a grain of salt and keep in mind that they may be incorrect/incomplete or that you may be reading something into them that isn’t actually there, sparked by your concern about what you encountered.
I hope that is of some assistance. If not, my apologies.
