Windows Mobile: Total Commander
Total commander is a great File explorer for your Windows Mobile Device. Total commander operates much faster than many other file explorers I have tried, but not only that, Total Commander gives us many more features that you would expect only in a commercial release.
There is a search functions, an FTP client built in, and you are able to extract and create compressed files such as ZIP and CAB files. You have control of file properties and which program a particular file extension will load up in.
What more could you want from a file explorer for your Windows Mobile device? There is every chance that Total Commander has that feature covered also.
There are many versions available for various mobile and Windows platforms. I have tested the Public Beta 3 and found it to be great.
Being a beta release, you should expect a few bugs, though there are stable versions available too. The application has been around for a long time though, meaning that most of the bugs would have been sorted in previous versions.
