class dissect.fat.fat.FATFS(fh: BinaryIO, encoding: str = 'ibm437')¶

fh¶

encoding = 'ibm437'¶

get(path: str, dirent: DirectoryEntry | RootDirectory | None = None) → DirectoryEntry | RootDirectory¶

dissect.fat.fat.validate_bpb(bpb: dissect.fat.c_fat.c_fat.Bpb | bytes) → None¶

class dissect.fat.fat.FAT(fh: BinaryIO, fattype: dissect.fat.c_fat.Fattype)¶

fh¶

entry_count¶

get¶

chain(cluster: int) → collections.abc.Iterator[int]¶

runlist(cluster: int) → collections.abc.Iterator[tuple[int, int]]¶

Create a runlist from a cluster chain.

First two clusters are reserved, so substract those. Also combine consecutive clusters for a more efficient runlist.

class dissect.fat.fat.DirectoryEntry(fs: FATFS, fh: BinaryIO, parent: DirectoryEntry | RootDirectory | None = None)¶

fs¶

parent = None¶

dirent = None¶

ldirents = []¶

name = None¶

short_name = None¶
