On Windows 7, the following query used in folder search boxes fails to filter the files in a folder that have a "!" exclamation mark in them.
filename:!
Is there any way of doing this search please? Thanks.
In your specific example filename:"*!*"
seems to work in Win7 (Not sure about Vista)
I'd still recommend using 3rd-party tools like Agent Ransack, BareGrep or Everything if you need to search for files with weird names or the content of files not indexed by Windows. (On Win9x/NT5 you can type Win+F *.dll
Tab CreateThread
Enter and you will find all DLLs on all local drives that contain the string "CreateThread", doing the same on NT6 is impossible AFAIK!)
