what is a .lrs file?

To generate an e-book used by the Sony Portable Reader, LRS files are necessary. These are files known as Librie Reader Source Files because they contain source information that are needed for the creation of a Sony "BroadBand eBook". Saved in binary format, LRS files contain descriptions of the contents and properties of an e-book. These LRS files are also useful for generating LRF files which are also supported by a Sony Portable Reader as well as they are also used to generate LRS files from LRF files. Opening LRS files is possible for multiple platforms such as Linux, Windows and MAC using the Calibre software but these files can also be opened through BookDesigner application, an exclusive Windows program used for the conversion of different contents of texts to several e-book formats. There are also other applications used to open LRS files such as Makelrf and Canon Book Creator.

a word of warning

Be careful not to rename the extension on .lrs files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .lrs. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
