Most of the portable electronic gadgets use different types of memory cards such as SD, XD, and MMC etc. Before, older cameras were making use of smart media(SM) cards, which are still available but, these memory cards can store only less amount of files therefore, they are replaced by XD and SD cards. JPEG and JPG are the two file formats used for saving pictures in memory cards. JPG extension is used in Windows operating system whereas JPEG is used in Mac platform. In most digital cameras JPEG file format is by default made use for saving pictures. Generally, memory cards are used to store photographs in digital cameras. Although the memory cards posses several advantages over other type of storage devices, they are more prone to loss of data during image transfer from memory card to system. You can easily undelete JPG files, using some memory card recovery software or image recovery software.
Professional digital cameras capture pictures in different file format. The image format used by professional digital cameras includes SR2, SRF, ORF, NEF, CR2, CRW, RAF, ARW etc. There are probabilities of photo loss due to some logical failures in memory cards.
