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
Code: Select all
photoshop:SidecarForExtension="ARW "
If Photoshop > File > Open then save XMP it will have
Code: Select all
photoshop:SidecarForExtension="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.
