Organize all your files on CDs/DVDs: music, photo and video, downloaded archives... and browse your collection offline! This application is a powerful tool for catalogizing all CDs, DVDs, floppies, ZIP disks, or other removable media, hard drives, network drives, or even FTP servers on the Internet (they are called volumes). Entire structure of volumes can be catalogized as well as internal structure of various archive files (ZIP, RAR, ARJ, LZH, CAB, TAR/GZIP, 7ZIP, ACE, JAR and others) including self-extracting installers (EXE). The application can work with any type of files, be it programs from the Internet, CD magazines, music collections (e.g. MP3, OGG WMA, VQF or WAV), photo-albums, or anything else. The application can automatically include contents of various commonly used files (such as readme.txt, file_id.diz) entirely or just in part into a catalog (called a database). Files can be processed by filters that can extract file summary or even create a thumbnail of the file. The current version is equipped with 17 filters which can extract for example song/interpreter/album name from MP3 or OGG files; size, bit-depth, format and even thumbnail from images of over 40 file formats (JPG, GIF, TIF, PNG, BMP, PCX, CDR etc.); properties of various sound files; obtain title, keywords, author, statistics from office documents (such as MS Word and Excel); or just copyright holder, name and version from executables. Comments can be added to any volume or folder. Files and folders can be searched in the database even if the original media (or Internet connection for FTP servers) is not currently available and this works really fast. Disk Explorer Professional comes with a royalty-free viewer that can be used for free distribution of self-view databases created using a full version of Disk Explorer Professional even to users that do not have a copy of Disk Explorer Professional.
