It is intended to store file info that takes a significant time to determine --- e.g., the MD5 sum of a large file, to avoid uneccessarily recalculation. This may be particularly helpful for searching across many files for some specific property.File statistics are recalculated on demand. If the file size or modification time have changed since the calculations were last made, then they will be purged and recalculated.File information is stored on a per-directory basis. Each file info file is stored in a directory; the files to which it refers are in the same directory, and are referred as names without paths.CLASS CONSTANTSTYPE_CONSTANTSAs returned by the type method. These constants are exported by request, either individually, or together with the ':types' tag.TYPE_UNKNOWNFile type not identifiedTYPE_JPEGA 'JPEG' image file.TYPE_PARA 'par' (parity archive) file.
