in Finder, how can I see the origin of a file? On the Mac of a colleague, we can see from which server a file is downloaded. How can I change this?

You're amazing, thanks! :)

You can use Spotlight to find files obtained from a specific network server. Let's say I downloaded a file (not a screen capture) from the Deviant Art website. The following Spotlight query will find all files whose server name has "deviant" in the name string:

kind:image kMDItemWhereFroms:deviant

That Where from content also appears in a Get Info/Show Inspect (⌥⌘i) panel too.

And from the Terminal, one can see the kMDItemWhereFroms extended attribute assigned to the file:

xattr ./imagename.jpg
com.apple.metadata:kMDItemDownloadedDate
com.apple.metadata:kMDItemWhereFroms

and remove that particular extended attribute via:

xattr -d com.apple.metadata:kMDItemWhereFroms ./imagename.jpg
xattr ./imagename.jpg
com.apple.metadata:kMDItemDownloadedDate



What I meant to post before the hosting software interfered:

You can use Spotlight to find files obtained from a specific remote server. Let's say I downloaded a file (not a screen capture) from the antmarch website. The following Spotlight query will find all files whose server name has "ant" in the name string:

kind:image kMDItemWhereFroms:ant

The Where from content also appears in a Get Info/Show Inspector (⌥⌘i) panel too.

Although one can remove the extended attribute from the file in the Terminal via xattr, the Finder Get Info panel continues to display the Where from server information. One must restart the Finder for the same file to no longer show the Where froms information after using xattr.

I'm not sure there is a way, but perhaps describing it in more detail would help.
