Xsparse is an auxiliary program that expands condensed sparse files back to their original state. You will need this utility if you have a POSIX archive, created by GNU tar, which contains sparse members and need to extract files from this archive using a third-party tar, that does not support sparse extensions.


The utility is distributed in source form: xsparse.c.


To compile the utility, run

cc -oxsparse xsparse.c
