[x] I performed a cursory search to see if the feature request is relevant, not redundant, nor in conflict with other tickets.

Is your feature request related to a problem? Please describe. Since both DirListData.EntryName and TempName are both OS_MAX_PATH_LENGTH, and and the os_dirent_t FileName is limited by OS_MAX_FILE_NAME, the first condition below can never be false: https://github.com/nasa/FM/blob/9210c2d314d3506fb50560d9bc6513c2b7fb4983/fsw/src/fm_child.c#L1496
