Batch hash checker? : Othor Games

Is there a freeware that can check entire folders of files, and generate a txt file and saves it in the folder? CRC or MD5 are all fine.

It copies to clipboard so you have to manage the save file manually.

for today's oses and hdds, how unlikely is data corruption? I just checked some files burnt on to dvds and moved to external hdds months ago, and they all matched. This is after I defraged the HDD inside my pc that the file was created on. 4 copies of the same data on different media, all passed.

So long as everything is going fine, the risk of data corruption is minimal.

Things like network hiccups, system freezes, damaged hardware, power outages/surges, etc are what'll increase the chances of file corruption.

Is that for active files only?

So if for any file you don't have the MD5 info on the original version/copy, is there any way you can try to "test" if a file is corrupted?

Applications may be unable to run, but for images, videos and raw audio, is there any way to probe for signs of corruption?

Like Defron said watch out for power outages. I had one last weekend (I have generators in my neighborhood but the power will still cut out for about 5 seconds before popping back on)
It corrupted a fairly new install of Windows on my SSD. It would boot fine. But any program I would try to run would result in an error saying missing or corrupt .dll files.

I only backup important data usually such as my documents folders and files. I keep an encrypted hard drive with all my backups at an offsite location.

I wrote a program to do MD5, SHA1, SHA256, SHA512 hashes and verify on an individual basis and have been meaning to implement batch functionality soon. College and life just got in the way but I think I will pick the project back up in the near future if you still need something when I get it done.
