The pcmanfm filemanagerdoes not have some of the system integration that nautilus, Vinux's default filemanagerprovides such as send to and UbuntuOne functions, but its feature set is flexible enough that many users find that pcmanfm meets almost all of their file management needs.
Pcmanfm's main advantage is its speed. You can browse even very large directories as soon as you open them with almost no lag in orca response.
PCMANFM was included in most Vinux3.x releases. To install pit on Vinux4, Ubuntu, or many other Debian based distros type
sudo apt-get install pcmanfm
in a console or gnome terminal.
For good accessibility set the default view to detailed list.
This is done in the general settings tab of the window that opens when you enter on preferences found under edit in the main pcmanfm menu-bar. It can also be set temporarily in the view menu. In the display tab icon size can be changed to improved visibility for those with some sight. Preferences are organized in four tabs: general, display, volume management and advanced. Most defaults should be good for most users, but take a look and decide for yourself.
Many pcmanfm options are only available in contextual menus that can be opened with the menu-key or by using numpad star "*" or its laptop equivalent. In the contextual menus you can choose which program to open a file with, see and change file properties, and do things like extract or compress files. When no available option does what you want, but you know how to do the deed on the command line; choose the open current folder as root option found in the tools menu, (f4 is keyboard shortcut for this). If you have bookmarked directories in the nautilus file manager they will appear in pcmanfm, and any you add with pcmanfm will show up in nautilus.
Tip: Set orca to read tables by cell and use left and right arrows to hear name, file size, date modified, etc one at a time. Toggle between read by cell and read by row with orca-key f11.
