@sgunhouse Thank you very much !
FYI , I have quite a few [[ .dat ]] files works for me against Opera , such as :
[ After making modification I hit the below .bat file ]
The following can copy the most recent change of Menu & toolbar files to my dropbox as a backup
robocopy "D:\Opera\profile\mail" "D:\Dropbox" standard_menu.ini
robocopy "D:\Opera\profile\mail" "D:\Dropbox" standard_toolbar.ini
[ When Opera close before restarting I have another .bat file to do the vice verse of above ]
The following can move back my backu of Menu & toolbar files to it's original file location in Opera
robocopy "D:\Dropbox" "D:\Opera\profile\mail" standard_menu.ini
robocopy "D:\Dropbox" "D:\Opera\profile\mail" standard_toolbar.ini
It is due my custom settings wasn't memorized by Opera in some occasions which was bothersome & time consuming to rebuild them in case of Opera forgotten.
Same to the Columns I asked , if there is any method I can create some sort of .dat file like above mentioned to robotcopy.
