Tried out the system and I like it as it is free from unnecessary interface clutters. Noted on one thing: it does not support mixture of characters such as chinese, arabic and english together. Sometimes, there are files containing such situations. I tried to change the character sets in \quixplorer4.0beta\_lang\en.php (line 5) from iso-8859-1 to utf-8 and it seems to work initially. All the web interface looks nice.
But when I tried to view the file naming at the OS level, it seems like it is jumbled up (with weird characters)... then I tried to have a multilingual character filename placed into the folder directly (not through the web interface) to see if it reads well, but it ends up gaving me read failure... php problem or OS problem?
