Just curious - what's the difference between FARR and UltraSearch

(1/4) > >>

In speed of finding files...can FARR search this way too
I tried the widow search,FARR search and XYPlorer search but all of them are not nearly as fast as UltraSearch

C:\ - 46907 Files and 9605 Folders
D:\ - 22649 Files and 1344 Folders

69556 Files
23993 Folders
All of the programs are searching hidden/system folders too and no one of them are using any filters to make the search faster...I also restarted the PC and disable the indexing service before the test
 
Explorer -  1 minute and 47 seconds(after all of the tests I set the indexing service to manual and stop it and then the files were find for 60 seconds)
XYPlorer - 12 seconds
FARR - 16 seconds
UltraSearch - Almost 2 seconds

32 files

No matter what I try UltraSearch always find the files almost immediately(even just typing .exe)

cyberdiva:
How does UltraSearch compare with Everything Search?  I find Everything extraordinarily fast, but I've never tried UltraSearch.

vsub:
Everything is unbelievably fast(it's either the same speed or faster)
I just started the program and I didn't change any settings...the program first scanned the hdd really fast and give me a list of all of the files I have on it and then when I just paste the same name I used for the other program,the result appear in an instant

All those files and folders and the database file that the program creates is ~500kb

db90h:
The search algorithm used is most likely the difference. You see, when the data is cataloged, the efficiency of the format in which it is stored (the data tree/algorithm) determines how fast it can later be recalled. This is CS 101. A bad algorithm can take 100 seconds and a good algorithm 0.1 seconds, that is how big a difference there is. Of course, the algorithms aren't rated in 'seconds', but rather in O notation, which I'll spare you the details of (basically a way to mathematically represent how long a search takes).

That is why explorer takes so long when you turned off indexing, it is doing a linear search, the slowest possible.

Other factors can also play a role. Such as the amount of data indexed. Some of these products may index more data than others. Etc...

vsub:
Ok thanks for the explanation but why FARR is not maded to work for example like Everything(~500kb database for more than 60000 files is extremely small cost)...is there is something bad about the method Everything uses and that's why FARR is not searching that way too?
