Hi AllI use an external drive to make a windows 7 backup from 2 pc's. When I try to use third party software treesize to caclulate space on it, it can not do it properly because files which were created on another pc are protected. Some files fail to change their permissions when I try to change folder permissions including files and folders in it.For instance, .vhd files are changed. .xml files resist to any change.Also, I was only able to change permissions to 'everyone' for read and read & execute. Other permissions were not changed.As I said: .xml files did not change at all.How I can go and change all files in folder by old good 'XP' way?Another question is next. I am annoyed by costant security prompts like: 'it requires Administrative permissions' or similar. Is there any settings which will stop these prompts. I am a member of administrators group on my pc.gene

Thank you so much. I find this feature so annoying. I am still using old software - word and others. This is another question which I do not want to discuss - why nothing is compatible with windows 7.Taking into consideration that me and millions others use Windows 7 personal edition these precautions are really bad architectural decision.gene

These backup files are protected. You can see that the only certain users have permissions to access or modify it. On another computer these users are listed as a series user ID. Backup files are highly protected because they contain personal data. In some scenarios users would backup to a shared storage on network. We must pay attention on privacies protection. Therefore you are not able to change the permissions as your wish for this kind of files.Arthur Xie - MSFT
