Need to change the location of settings

[B.Douille]

• <--// Moderator's note: This topic has been split off from “Info about XnView's settings (store & load)”. //-->

I'm using Xnview with Windows Seven and the various options for the location of the ini file seems not working as expected. See below, it's always in the user's profile.
I want to have a single setup for all users in my family. Mainly I want the file modified dates to be preserved if a changes are made in the public picture library.

Setting: .ini in directory User
About says "C:\Users\[username]\AppData\Roaming\XnView\xnview.ini"
Actual location "c:\Users\[username]\AppData\Roaming\XnView"

Setting: .ini in directory Windows
About says "C:\windows\xnview.ini"
Actual location "c:\Users\[username]\AppData\Local\VirtualStore\Windows" not sharable

Setting: .ini in directory XnView
About says "C:\Program Files\XnView\xnview.ini"
Actual location "c:\Users\[username]\AppData\Local\VirtualStore\Program Files\XnView" not sharable

Best regards

Is this a UAC issue?

In Windows 7 writing to the Program or Windows folders requires Admin rights, but when XnView is run from a User account the usual UAC request for the Admin password doesn't appear, the expected write operation doesn't occur but there is no indication that it hasn't been performed...

Is this a UAC issue?

I think so. In the case I did the test with an administrative account so the password was not required. At least should I have seen the popup to confirm the access. This does not happen.

If the Windows directory is protected, why not use the C:\ProgramData (equiv. to "All Users\Application Data") ?

Same with XnView MP - only workaround is to deploy via the ZIP package in a non-protected, public directory. Annoying.

I'm back with the question of the actual path used by the system (Windows 7 as an example). I put a message some time ago but apparently it didn't triggered that much attention. Further comments were posted with information not verified, assuming that nothing have changed in the Windows world
Unless you have an administrator account (Superuser in Unix world) , the current choice, where to store the XnView configuration file is virtual and drive to the same result: It's always in the user profile folder

This is because from Windows Vista all write tentative to System and Program folders is refused, limited to read only for normal users (as Unix always did). To preserve compatibility with old programs it creates virtual links to specific folders that emulates these now restricted folders, keeping r/w access. These new folders are in the individual user profile. See below:

Setting: .ini in directory User
About says "C:\Users\[username]\AppData\Roaming\XnView\xnview.ini"
Actual location "c:\Users\[username]\AppData\Roaming\XnView" that's correct

Setting: .ini in directory Windows
About says "C:\windows\xnview.ini" Have a look, you'll never find the .ini file here
Actual location "c:\Users\[username]\AppData\Local\VirtualStore\Windows" emulation not sharable

Setting: .ini in directory XnView
About says "C:\Program Files\XnView\xnview.ini" Have a look, you'll never find the .ini file here
Actual location "c:\Users\[username]\AppData\Local\VirtualStore\Program Files\XnView" emulation not sharable

Currently, the 3 options available are all equivalent and finally doesn't allow to share settings between users. I suggest that we keep 2 options only:
XnView.ini in the User directory for individual preferences (actual path = %APPDATA%\XnView as for now)
XnView.ini in All users directory to share preferences between users (actual path = %ALLUSERSPROFILE%\XnView)

Hello,

Can we have a change implemented in a future version?

Unless I'm wrong, the options are made to switch from "Single user mode" aka each user of a machine have is own settings to "Multiple users mode" aka all users shares a same set of settings. Since my original post there are now 2 options only, where to store the .ini file but still this is of no help as it's 100% equivalent as explained in my previous posts.

For the time being, the only way to have a true "Multi-user mode" is to use the ZIP'd package and copy the files in a folder with r/w access for all (personally I use C:\ProgramData). Some anti-virus may dislike this.

by default, settings are in user data

[B.Douille]

Yes, with the default option "User", settings are stored in the user profile. Each user of the machine sets his own preferences, independently:


The original idea of the 2nd option "Program (XnView)" was to have a single .ini file so all users have the same settings for consistency (for exemple "Keep original date" or "Export rating in XMP"). The issue is currently it is not possible, unless you are Administrator of the machine:

This is a security enforcement since Windows Vista where a normal user cannot affect the \Program folder and is similar to the restrictions in the Unix world.
The solution is to store the .ini file in a folder made for purpose: C:\ProgramData (system variable %ProgramData=%) - equivalent to /etc in Unix world

[B.Douille]

Back to this proposal, I see there is a "Custom" option available for the catalog and for other files. Why not adding this option for the .ini files as well ?
This would allow anyone to select \ProgramData\XnViewMP (example for Windows) which is the right location to store the .ini file in case one would ensure the settings are consistent for all users of the machine.

Reminder the current option "Program (XnView)" doesn't work (Windows, Mac, Linux) as the program folder is always protected against tampering the system. To me this option is useless - only use could be for "Portable version" on USB key.

The best would be to replace the Program option by a customisable option (set by default to \ProgramData\XnViewMP vor Windows and equivalent for Mac and Linux)

"Program (XnView)" = "Application directory", this option should remain as is, precisely because of portability (I would rename it though).
If you put app in a folder where user does not have write permissions, it's not the app's problem.

that may be handy

I'm happy you received my proposal positively

I just spent some more time to compare fresh installs of MP and Classic and the way they scan some folders if configuration file(s) already exist (if not, the program offers a selection of 2-3 options). This analysis leads to a more detailed proposal as below :

- The current default option is right, no need to change : Config per user, stored in %APPDATA%\... ($XDG_CONFIG_HOME/... or $home\.config... for Linux)

- The second option, config shared all users targets the %Program Files% folder. I agree that in some situations this should remain (see next). But, in most cases XnView is deployed via a standard setup.exe (or .deb on Linux) and the target folder is protected, cannot store the config files.
What I suggest is rather than just warn the user, the location should be transparently directed to %ProgramData% ($XDG_STATE_HOME for Linux?). This folder is made for purpose, with r/w access by all users of the machine.

- For portable distribution (and ZIP)?) a .ini file should be included. Doing so the program do not ask and will use the file provided in the program folder (with r/w access, no pb on USB key). Once the .ini file is found the information on Settings > Integration > Paths should reflect the actual location where is the .ini file in use (one of the 2 options above). Doing so prevents use/alterations of existing configuration files on the host machine and unexpected behavior when a USB key is/has been inserted.

Bellow is a screenshot of the current behavior of the option "Program (XnView)" when it was installed via normal setup. The warning doesn't mean anything for an average user, may lead to unsecured change on the system and do not deliver the expected feature of sharing a consistent layout, shortcuts, toolbars, labels,... across all users of the machine. My proposal solves this.
