LFS file extension is used by Samsung in its mobile devices. LFS file is a type of log structured file system. In this format the original data and its related metadata is written sequentially in log.
The log structured system the data is treated as circular log and due to this reason the new data is written to the head of the log in a sequence. This technique allows efficient writing to the file and recovery from system crash is much improved with this method. In case of flash media the performance of this method is low. LFS files are used by Samsung as system files.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .LFS file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .LFS file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .LFS file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
