Hi,
seems, I'm number three with this file. The facts:
- I'm running WinXP.
- aux.txz has been created 29.June2003, half a year after I bought the computer.
- It resides in system32.
- It gets changed (I guess extended) every time I connect to the internet.
- It's got 34,197 KB (!) right now.
- It's attribute is only "A", no system, no hidden...
- It has NO entry in the Explorer's column "owner".
- Deleting isn't possible. Seems to be locked by a process (don't know yet which one).
- Trying to move it leads - INDEPENDENT of the destination dir - to the response:
..'This directory already contains a file "aux."
..Do you wish to replace the existing file 0 byte
..by this one 'icon' 0 byte ?'
- There is NO string "aux.txz" in the registry.
- But there are a lot of keys mentioning "txz", e.g.:
..HKCR/.txz/(standard) of the type REG_SZ and the value "txz_auto_file",
..HKCR/txz_auto_file/shell/... ,
..HKCR/txz_auto_file/open/... and some others
..connecting ".txz" to notepad.exe .
- Opening Notepad and loading aux.txz results in 'access denied'.
- Trying to store some information using the file name "AUX.TXZ.txt" gave me the following response:
..'This file name is a reserved device name.
..Choose a different name.'
- I never installed any game. So that's no possibility of the origin of aux.txz .

Anyone out there, who is able to help in any way?
Thanks so far...
