Such as allowable characters in the ++directory entries, length of the file name, length of the ++pathname, size of a single file, and number of files, etc. ++ ++Resources limitations ++~~~~~~~~~~~~~~~~~~~~~ ++ ++The lack of memory or disk volume would lead to decompression ++failed. For example, decompression bombs (aka `ZIP bomb`_) apply ++to zipfile library that can cause disk volume exhaustion. ++ ++Interruption ++~~~~~~~~~~~~ ++ ++Interruption during the decompression, such as pressing control-C ++or killing the decompression process may result in incomplete ++decompression of the archive. ++ ++Default behaviors of extraction ++~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ++ ++Not knowing the default extraction behaviors can cause unexpected ++decompression results.
