I've just migrated from XP to Vista and one issue I can't resolve is why right clicking on large files ( around 20gb - typically hard drive image files ) takes forever - along with a subsequent delete command which then comes up with a dialog box saying it's preparing ........ and it basically takes minutes to do what XP did in a split second.
This is on an attached USB external hard drive which I have since put back on my XP system to test and it still works fine.
There's no problem with small files, so it's definitely something to do with the file size that Vista is handling in a different way.
There seems to be lots of history about Vista performance issues - particularly around handling large files but all the fixes I've seen seem to have been put right in SP1 which I am using. I have also installed all updates, both critical and optional, so can only conclude my system is as up to date as it can be.
I don't believe it's a hard drive or fragmentation issue as it still works fine from my XP box.
The only other thing I've tried is to disable indexing on the external drive in question but this doesn't seem to make any difference either.
Has anyone come across this type of problem?
