Can I Delete this? UrlCache MMF Ver. 5.2

[Diggy]

There is this file on the computer in the Temp file. It's called Index.dat,
and when I open it with Notepad, there's a bunch of unreadable symbols, but
there is a readable title: Client UrlCache MMF Ver 5.2

When I did a search for it on Google, I got a ton of hits for porn sites.
So was this file put in there by a porn site? I can't find any other info
on what this might be.

in windows XP if you delete the file ....when you reboot
it will re-appear. if you don't reboot and some function
needs the file it should warn you it is missing. restore
from recycle bin.

Besides wasting space, these files can be used to spy on you.
Each of Internet Explorer's primary folders (directories) - Cache, Cookies and History make use
of an indexing technique to maintain information. The index information is contained in files named
Index.dat.
For Cookies and for Cache, the Index.dat files are basically URL entries and pointers to the
associated real files.
URL is an acronym for Uniform Resource Locator which is geek for an Internet Address.
For History, no files are referenced (this is the collection of URL entries used for
AutoComplete and for controlling the highlighting of imbedded links on the Web pages). All three
contain the actual URL plus date/time stamps and reference counts.
