InocuLAN AntiVirus renamed data
File type: Various data file
An in2 file is a file renamed by InocuLAN AntiVirus, an antivirus application for Novell NetWare and Windows NT servers.
The .in2 file extension replaces the file's original extension when InocuLAN AntiVirus quarantines a potentially dangerous file.

The in2 file extension is associated with InocuLAN AntiVirus, which was designed to protect LAN servers running Novell NetWare and Windows NT.
When the software detects a potentially dangerous file, it quarantines the file by changing its original file extension to .in2. This breaks the usual Windows program association and prevents the file from being executed or launched through its associated program.
An in2 file is therefore a renamed quarantined file rather than a separate document format. InocuLAN AntiVirus is obsolete.
An in2 file is not normally opened directly. The .in2 extension does not identify the file's original type, so it cannot be opened reliably as a distinct format.
If the file is known to be safe, restoring its original extension may make it usable with the appropriate program. Do not restore the extension or launch the file unless it has been checked for malware.
There is no meaningful conversion for an in2 file. The .in2 extension marks a quarantined file rather than a standalone format.
If the file is known to be safe and needs to be recovered, restoring its original filename extension may make it usable again. This is a rename, not a conversion, and should be done only after appropriate malware checks.
