This is a read-only exFAT implementation based on the Microsoft-published specs (exFAT file system specification). The primary purpose of this project is to provide an unprivileged API to access an exFAT filesystem from any platform. This project also provides several tools that can be used to explore the filesystem and extract files from it.
- exfat_list_contents: List all files with or without complete directory-entry information.
- exfat_extract_file: Extract a single file to a file or STDOUT. May also be used to print all clusters and sectors visited for the extraction.
- exfat_print_boot_sector_header: Dump filesystem parameters. Largely sourced from the boot-sector header.
-
All entry-types are parsed as per the requirements of the specification. However:
-
Up-case tables, which support case insensitivity, are not read and therefore not applied. As a result, all file-operations are case-sensitive (and the villagers rejoiced).
-
Allocation bitmaps are not read, so it's not possible to know which clusters are or are not used. This is not required for browsing the filesystem or reading files.
-
-
Timestamps are accurate to one second.
