when saving a file under C:\Program Files\Geany (default location) the files are not actually saved, only geany can see them in that folder and no other program can (windows explorer, total commander ect)
The files are still accessible after geany is closed and reopened again, only that geany sees them, and no other program can
tested on Geany 0.21 for windows, running without administrative priviledge (UAC), windows 7 32bit
Looks like the same issue than in https://sourceforge.net/tracker/?func=detail&aid=3566329&group_id=153444&atid=787791 where codebrainz found what is the issue (quoting him):
Is it the Windows UAC[1] sneaking files around behind your back?
"Applications written with the assumption that the user will be running
with administrator privileges experienced problems in earlier versions of
Windows when run from limited user accounts, often because they attempted
to write to machine-wide or system directories (such as Program Files) or
registry keys (notably HKLM). UAC attempts to alleviate this using File and
Registry Virtualization, which redirects writes (and subsequent reads) to a
per-user location within the user’s profile. For example, if an
application attempts to write to “C:\program
files\appname\settings.ini” and the user doesn’t have permissions to
write to that directory, the write will get redirected to
“C:\Users\username\AppData\Local\VirtualStore\Program
Files\appname\settings.ini”. "

Should be fixed in commit https://github.com/geany/geany/commit/1613f93ad0adbb32faf77172930f981cff4ff8a5.
