The LPAQ5 format stores one or more files in compressed archive form. It is associated with PeaZip, which can read the format on Microsoft Windows.
An lpaq5 file contains compressed archive data rather than a document intended to be opened by a standard office or media application. The files inside the archive must be extracted before they can be used normally.
The lpaq5 format is reported as malicious software. The extension alone does not prove that an archive is malicious, but an lpaq5 file from an unknown or untrusted source should be treated with caution and scanned before extraction.
On Microsoft Windows, open the lpaq5 file with PeaZip. Use the program's archive-opening or extraction function to view and unpack its contents.
Because lpaq5 files have been reported in connection with malicious software, scan an unfamiliar archive before opening or extracting it.
An lpaq5 file normally does not need to be converted to access its contents. Open it with PeaZip and extract the files.
To create an archive in another format, extract the contents first and then use PeaZip to create a new archive in a supported format. This preserves the files but does not convert the original LPAQ5 compression directly.
