When Acronis Agent for Windows is installed, a folder Itzam is created on the following location:
- Windows XP/2003: C:\Documents and Settings\All Users\Application Data\Acronis\Temp\
- Windows Vista/7/2008: C:\ProgramData\Acronis\Temp\
The purpose of this folder is to store a temporary database which contains information about files/folders tree during file-level operations. This database is stored in .dat~ format and ensures quick and proper access to the respective data.

You may want to change this if the capacity of the disk with the ProgramData folder on the affected machine (Agent or AMS) is an issue.
