WinRAR 5.30 Beta 2 发布，更新内容如下：
SFX module sets sfxstime environment variable, which contains the module start time in "YYYY-MM-DD-HH-MM-SS-ms" format. You can specify it in Path command if you need to generate a time based unique installation path, such as "Path=myapp-%sfxstime%".
在下列“转换压缩文件”命令的情况下，更少的密码请求：
if "Convert archives" is applied to archive with encrypted file names, which contents is currently displayed in WinRAR;
if archive produced by "Convert archives" includes encrypted file names.
Bugs 修复:
RAR volumes renamed from standard .part1.rar, .part2.rar to .001, .002 are recognized and processed correctly now. Previous beta opened them as set of usual split files, not as RAR volumes;
reports produced with "Generate report" command contained invalid CRC32 checksums for non-archived files;
"rar x arcname.rar d:" command unpacks files to d: current folder. Previous version unpacked them to d: root folder;
archive comment was not encrypted if added to archive with encrypted headers using "c" command without -hp switch. This beta encrypts an archive comment in such case.
