Re: XnView MP and Photoshop *.ACR files.

Still facing lots of issues and confusion with how XnViewMP handles sidecars.
When i assign Photoshop to Open With (Alt+1) menu and start it with on 007.ARW then it creates sidecar 007.XMP.
1. However that 007.XMP is only used when i use Open With (Alt+1) from XnViewMP menu, if i open using Photoshop > File > Open and select 007.ARW it does NOT load 007.XMP automatically as it should.
2. If Photoshop > File > Open used then changes made to 007.ARW in Adobe Camera Raw then it saves new sidecar file 007.arw_xmp because file 007.XMP already exists.
Pinpointed the problem its because when opening 007.ARW with Open With (Alt+1) and save changes then inside 007.XMP it adds line
space after "ARW ", this is reason it never being auto loaded from Photoshop Photoshop > File > Open
If Photoshop > File > Open then save XMP it will have
no space after "ARW", then XMP loads properly when opening from Photoshop > File > Open and select 007.ARW
From what i understand when opening one file in XnViewMP using Alt+1 then it adds spaced "ARW " to that file's XMP, however if opening multiple files in XnViewMP then it adds spaced "ARW " only to the last file in series, must be something in part of source that supply file path or file name to external program.
