Bug ID: 155025
Summary: Consider LocalAppData folder on Windows as
"temporary", and do not offer saving into it
Product: LibreOffice
Version: unspecified
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Keywords: difficultyBeginner, easyHack, skillCpp, skillWindows
Severity: normal
Priority: medium
Component: LibreOffice

There is a recurring problem that people keep documents that they open from,
say, Windows Mail, right where these documents were put by the mailer
application. See bug 117578; also questions on Ask like
https://ask.libreoffice.org/t/why-were-files-saved-to-a-temporary-folder/33820
and
https://ask.libreoffice.org/t/my-files-will-not-open-in-libre-office-writer/90897.
Even when the temporary file had been marked read-only by the generating
application (which seems to happen in Windows Mail, based on my local testing),
using Save As suggests the same directory (like
"C:\Users\user\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Files\S0\67445\Attachments"),
and a careless user could just rename and save there, which would later lead to
disaster, when the application that manages that temporary directory decides to
clean it up.
A similar problem was tracked in bug 80807 and bug 109537. The solution was to
make sure not to suggest the same location, when it's known that it's in a
temporary path.
The proposal and the easy hack here is to treat Windows' LocalAppData folder as
a whole as such a temporary location, because its purpose is described to be
for "program settings, IE cookies, IE browsing history, temporary files created
by applications"; and do not offer to save into it, when showing the Save As
dialog.
The code pointer is the commit fixing bug 109537 in the same way as suggested
here.
