IIL File – What is .iil file and how to open it?

CleanSweep Installation Log Files

IIL files are CleanSweep Installation Log files created by Symantec, a leading provider of security and data management software. These files contain detailed information about the installation process of CleanSweep, a popular utility software that scans and removes outdated and unnecessary files from a computer system. The log files are generated by the CleanSweep installer and record various events and actions that occur during the installation.

Content and Usage

IIL files store crucial information such as the timestamp of the installation, the installer version, the operating system version, and a detailed list of all files installed and modified. They also contain error messages and warnings that may have occurred during the installation process, providing valuable insights for troubleshooting any potential issues. IIL files are primarily used by technical support teams, system administrators, and users to analyze and resolve installation-related problems. By examining the log file, they can identify the root cause of errors and suggest appropriate solutions.

Opening IIL Files

IIL (CleanSweep Installation Log) files are associated with CleanSweep, a discontinued software utility for PC optimization. These files contain a record of the CleanSweep installation process, providing information about the installation date, time, version, and any errors encountered. To open an IIL file, you will need to convert it to a text-based format since it is not a commonly supported file type.

Conversion and Viewing

One method of converting an IIL file to a text format is through the command prompt. Open the command prompt as an administrator and navigate to the directory where the IIL file is located. Type the following command:


C:\Path\To\IIL\File>type file.iil > file.txt


This command will create a text file (.txt) in the same directory containing the IIL file’s contents. You can now open the .txt file using a text editor such as Notepad or WordPad to view the installation log.

CleanSweep Installation Log (IIL File)

An IIL file is a text file that stores the log of the installation process for CleanSweep, a disk cleanup and optimization utility developed by Symantec. It contains detailed information about the files and registry changes made during the installation, as well as any errors or warnings that may have occurred. The file is typically located in the “%TEMP%\CleanSweep” folder, and is named “Install.iil”.

Technical Specifications and Usage

IIL files are plain text files and can be opened with any text editor, such as Notepad or WordPad. They are typically divided into sections, each of which documents a specific part of the installation process. The “Date” section specifies the date and time of the installation. The “Files” section lists the files that were installed, along with their destination paths. The “Registry” section lists the registry changes that were made during the installation. The “Errors” section lists any errors or warnings that occurred during the installation.

IIL files are primarily useful for troubleshooting installation issues. By examining the log file, users can identify potential issues that may have caused the installation to fail. They can also be used to track the progress of an installation, or to verify that all of the necessary files and registry changes were made correctly.
