WinRAR properly recognizes archives with a wrong file extension, containing an archive in another format stored without compression.
For example, if host.rar, storing nested.zip inside, was renamed to host.zip, WinRAR 7.20 could display nested.zip contents when opening such host.zip. This version displays host.zip contents.
Similarly to Windows Explorer, the first click on size and time columns in WinRAR file list sets the reverse sort mode with largest and latest files at the top.
Switch -s=e performs the case insensitive file extension comparison in Windows. Unlike previous versions, solid statistics isn't reset anymore for file extensions differing only by case.
If self-extracting archive attempts to extract files to a folder requring administrator rights and elevation prompt is cancelled by user, the archive quits silently instead of issuing the folder access error.
Bugs fixed:
WinRAR 7.20 could produce a broken archive when deleting files from solid archives in old RAR4 format. As a result of this fix, deleting files in solid RAR4 archives now involves the full archive repacking, similar to WinRAR versions preceding 7.20. It doesn't affect archives in the modern RAR5 format;
with a rare combination of source data type and compression parameters, WinRAR 7.x could crash when compressing source data. Such crash was more likely when processing large amount of poorly compressible data;
WinRAR 7.20 couldn't unpack ZIP archives containing file comment fields;
switch -tl didn't set the latest time when used with RAR 7.20 "ch" command;
extraction command didn't automatically replace device names like "aux", when unpacking archives containing such reserved names;
if folder shortcut was double clicked in "Save WinRAR settings as" dialog when exporting WinRAR settings, folder shortcut itself was overwritten with settings data instead of opening a target folder.
