Well, the darned easiest thing would be to use my most beloved Utility: (that's right: capital U) Windows Commander. )
It does about everything you'll ever want and more.
Download Windows Commander
Find an appropriate keygen at Astalavista.
Have a look at the WinCommander revision pages to see what's possible with this baby:[list=1]Click on the "display" tab and check the third check thingie (Show hidden/system files) Don't worry, after you've deleted a few system files you'll become an expert soon enough!
[li]Hit + on the numeric keyboard, press enter (thus selecting all files) or enter any selection (*.jpg) and you'll only select jpg files.
[/li][li]Select several directories and go Files/calculate occupied space. You'll find that WinCommander is always exaggerating filesize. That's because it measures files in bits, and Windows does it in bytes.
[/li][li]You can doubleclick on any packed file (ZIP, ARJ, LZH, RAR, UC2, TAR, GZ, CAB, ACE ) and see it as a directorty, but you can also add, edit remove files from the archive!
[/li][li]Click on the 11th icon on the menu bar an you'll open the notepad: very easy for editing HTML files!
[/li][li]Add any program you want on the menu bar!
[/li][li]You can also FTP with it! (although Leechftp is better)
[/li][li]Select a few files/directories and go Files/Pack, choose your favourite packer and you're on your way!
[/li][li]For archives that use passwords, you will need the original packers, rather than the .dll's Wincommander uses.
[/li][li]Download the .exe's and copy them 2 the WinCommander directory, then go Configuration/options/packers and click on the button to show WinCommander where they are.
[/li][li]Associate filetypes with programs
[/li][li]Remane a bunch of files easily
[li]Install Windows Commander.
[/li][li]Startup WinCommander (click the correct number button), hit enter on the options menu.
[/li][li]Use the left window for the next operation: doublecklick the file that you found in Astalavista and copy (F5) the .exe (serialkey generator) file to the directory where u installed the Wincommander program (go to the directory where u installed the Wincommander program in the right window)
[/li][li]Select the keygenerator file in the right window and hit F5 (copy) and enter.
[/li][li]Doubleclick the keygenerator in the right window and CLOSE WINDOWS COMMANDER. Fill in anything u want in the keyGen and hit register.
[/li][li]Restart WinCommander (regged this time) and go configuration/options/layout, check "show Drive buttons" and "show 2 drive buttons bar"
[/li][li]Then click the "operation" tab Choose how you want to select multiple files: the upper one has u select (and unselect) by dragging with the right mousebutton depressed, the second one as Windows does it normally (with shift and Ctrl)
[/li]Also check the fourth check thingie (Also select directories)
Go to the windows/system directory and look at all the hidden and system files (they have an exclamation mark before the filename)!
