คำแปลของ "sparse file" เป็น ไทย

A file that is handled in a way that requires much less disk space than would otherwise be needed. Sparse support allows an application to create very large files without committing disk space for those regions of the file that contain only zeros. For example, you can use sparse support to work with a 42-GB file in which you need to write data only to the first 64 KB (the rest of the file is zeroed).
