is there a utility to check the integrity of a file anywhere. I think I have a bad set of files on one laptop but don't want to overwrite good with bad when I try and consolodate several machines.

currently searching the topic but so far no answers.

it'll be personal files.

I use several machines depending on what I am doing so tend to cross deck files between them every few weeks then back up to the NAS but don't want to back up bad files.

Open the "Computer" window
Right-click on the drive in question
Select the "Tools" tab
In the Error-checking area, click <Check Now>.
I didn't think that checked the contents just the shell? I know I'm probably going to end up opening lots of files but wondered if there was a prog I could use. similar to the video and music file checkers.

chkdsk will look at all files, best to see if there are anymore, its pretty simple it will fix em and you can carry straight on
Chkdsk does not look at file level integrity, it just looks at the NTFS structure. You can have a zip file which will not open, but chkdsk won't tell you that.

not sure what got them but I did have a bad ram dimm in the laptop in question so I could have had copy errors. daftly I was trying to get everything sorted to cut down on duplicates within the directories so I could have a master backup. the idea is to make a good backup then backdown to the machines I use.

most copy utilites only tell me if the file is newer or a different size.

Why not just back up your back up first. Note the date of your suspect backups so you can see what's left of them after your next one or two backups, and check if they're corrupted when they are reduced to a number to make the job quick 'n easy.

teracopy came up with a load of errors when moving a few folders about, I was bouncing files in and out of external drives when upgrading laptop drives and have had the odd copy error come up and scrambled picture or cannot open pdf file sort of thing

If you have a NAS box, then put the backups into separate folders and when you come across a corrupt file, write the known good one over the duff one.
