LAR file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the LAR files:

The LAR file extension is used very often and mainly uses a defined LAR format. But the following two file formats are common:

• 85% of all LAR files use ZIP compression, so several files are compressed and saved in one LAR file. Most often they are 2 to 140 compressed files. File names are e.g. manifest.xml and \group\. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The file size is in the range of 2 KB to 17 MB. The following keywords are characteristic: group, liferay, portlet and model. Files like these are about portlet, pages, public, content, admin, data, licenses and dynamic.

All the rest of the LAR files (15%) have different formats. Often described as lists, private, display, forms, oris or journal. Drag & drop your file here to see the file format and a preview of your LAR file!
