SelectRandom - a script command which allows you to randomly select items by type, count, size, total-size or some other filters. Results can be selected, dumped to console, copied to file collections or returned in env/tab-variables.
"SelectRandom" is obsolete and won't receive any updates.
The functionality of this command has been moved into "SelectEx". Find it here:

If you have trouble using it, the script config section offers a trigger to enable some console output, if that does not help, just ask! o)
For selecting a single item out of many, it is recommended to run "ScrollSelectionIntoView" after running "SelectRandom", to scroll the selected item into the visible area. Find it right here:
Examples - Usecases:
Select 10 random music albums folders and add these to winamp:
SelectRandom FOLDERS ITEMCOUNT=10 COMMANDS=WinampAddItems
Select a random file, run the doubleclick action and make item visible (chooses a movie and autom. launches player eg.):
SelectRandom FILES ACTION=dblclck COMMANDS=ScrollSelectionIntoView
Select 20 images and start slideshow:
SelectRandom FILES ITEMCOUNT=20 COMMANDS=Show SLIDESHOW
Select 1 file out of an "external" folder and provide result in an env- and tab-var called "Result.SelectRandom":
SelectRandom FILES PATH="C:\Items" ITEMCOUNT=1 SETTABVAR="Result.SelectRandom" SETENVVAR="Result.SelectRandom"
Examples - some more:
Select a random item:
Select 10 random items:
Select 10 random folders:
SelectRandom FOLDERS ITEMCOUNT=10
Select 50% of files:
SelectRandom FILES ITEMCOUNTPERC=50
Select a random number of random items:
Select 1-5 random items:
SelectRandom RANDOM ITEMCOUNT=5
Select a single file, or a single folder if there are at least 3 subfolders present.
This creates a button that when repeatedly pressed, opens random folders and eventually "doubleclicks" a file
SelectRandom FILES SINGLEFOLDER ACTION=dblclk
Select 50% of items
