Hmmm...I did some thinking about this and made a small change in the code. Please redownload the zip and let me know if v1.1.3.2 makes any difference in your tests. Thank you.

Hi skwire, thanks for the speedy update!

Just ran up 10 instances at the same time to test and no spurious "bad" results, so it looks good!

Thanks again

Ciao

Good to know; thanks for the report back.

BTW, SFV Ninja is single-threaded so I'm not certain how much benefit you're getting from running multiple instances. Just thought you'd like to know. Thanks for joining the site!

I guess the benefit (for me) is that I can fire up a bunch of instances in one go and set them to creating/verify checksums on a load of folders, then just leave them to get on with it - eg. overnight - rather than having to do each one sequentially.

Thanks again

Ciao

I see. However, doing it that way is definitely going to very taxing on your harddrives. Were you aware that one SFV Ninja instance can load multiple checksum files into its list?

Yes, thanks

My archiving "strategy" requires separate checksum files for each top level folder though, so when creating the files in the first place it's easier to just run up a separate instance per folder

Hm, seems like a bad idea to run multiple instances at one time, at least for long-running jobs. You'll see much decreased throughput (way worse than linear degradation), and all the back-and-forth action is going to be stressful on your harddrive heads.

If I run 3 instances against folders on 3 separate physical drives it's definitely quicker than running them one after another, and I can go to bed and forget about it

As for the wear on my drives - I figure that's why we have so many backups in the first place!

Ah, that's the key. I (and f0dder, I bet) thought you were working with one physical drive. =]

Website | Download v1.1.4 - 2012-09-22 * No longer writes the Unicode BOM to checksum files.

@Cornucopiae: This version should allow you to use the Unicode version and still generate checksum files that are compatible with non-Unicode apps like QuickSFV.

Hi skwire, thanks for the new update!

In AutoHotkey, there are no native hash/checksum commands. So, you have three options: 1) Use a command line executable, 2) a DLL, or 3) use a function library that somebody has developed. SFV Ninja uses number one and three. However, I've found that the function library, while very fast and accurate, has a tendency to crash randomly and I don't know why. So, I changed SFV Ninja to only use that function when absolutely necessary where before it was using it for smaller files because of its speed.

It is unfortunate that the library has tendency to crash. I'm using SFV Ninja v1.1.2 because it's faster. I'll wait for the news.

I'm very pleased with the program anyway!

Website | Download v1.1.5 - 2012-11-14 + Added "Always on top" button to the toolbar. ! Prevented exiting the app if a save operation is in process.

Been looking all over for a lightweight, simple and free file verification program and SFV Ninja fits perfectly. ^_^ Minor feature requests:

ability to delete from the file list
check/uncheck selected items from the right-click context menu. Alternatively press spacebar

Thanks for the great software!

Would deleting to the recycle bin be acceptable?

I dont mean physical deletion of the actual files, I mean from the file listing in SFV Ninja. :3 I know it's kinda unnecessary since you can just uncheck the files you dont want to verify, having the other request would be sufficient if it's too much trouble.

Ah, if that's what you mean, simply press the Delete key after highlighting the rows you want to remove.

Give this a build a thorough beating and let me know how it works for you, please.

This build has tendency to crash, like SFV Ninja v1.1.2. But speed is OK!
Thanks anyway!

Which operating system are you using?

Cornucopiae · « **Reply #95 on:** August 11, 2013, 03:03 PM »

winxp

skwire · « **Reply #96 on:** August 11, 2013, 03:13 PM »

It would crash on me as well under XP but, in my tests yesterday, I couldn't get it to crash under Windows 7.

skwire · « **Reply #97 on:** March 02, 2014, 04:27 AM »

@Cornucopiae: If you're still using SFV Ninja, would you mind trying this version and letting me know how it performs for you on XP?

Website | Download v1.1.7 - 2013-08-10 * Speed improvements (hopefully). * Row colouring improvements. ! "Open folder location" was broken.

Cornucopiae · « **Reply #98 on:** March 09, 2014, 05:54 PM »

skwire, this version is perfect!!!

So, I'll take this to say you have tested this under XP and aren't getting the random crashes you reported a while back? If so, right on, and thanks for testing.

Uh, yeah, that would be a problem, eh?

Please try the version below:

Website | Download v1.1.9 - 2014-03-09 ! Checksum dropdown wasn't functional due to toolbar changes in the 1.1.7 version. (Thanks, Cornucopiae)
