The other reference, to the SourceForge utility CorruptedPdFinder, is more useful, and gave partially useful results. This wastes a lot of time and processing on non-pdf files and makes this impractical to use on a large folder tree. If a file is not a pdf, it is converted to one for the analysis. But when I run it on a folder, it opens every file in the folder. I followed the instructions for that at that link. The link you provided suggests creating an action to run a Preflight analysis. This is a reply first to I'll reply separately to jphughan afterwards.

It's not clear whether installing a newer Windows Management Framework package onto an older version to gain PowerShell 5.1 will add this specific cmdlet, so if you're not using Windows 10, you might not be able to use this.

NOTE: The Get-FileHash cmdlet this script uses seems to have arrived in PowerShell 5.1, which was introduced with Windows 10 / Server 2016.
But if you just want spot checks, the script I've attached might do the trick for you. hide all identical files, or show only files that only exist on one side, etc. And you can filter the view to show your choice of those types of results, i.e. You can see files/folders that are identical, that are different, or that only exist in one location or the other. Either way, you just point it at two different folders and let it run, and if you enable Tree Mode view, it will give you a nicely presented view of the comparison results.

Its default comparison mode just compares file size and Date Modified timestamps, but you can set it to perform a full hash check. I use WinMerge when I need to compare two directories. If you want to compare all files in an entire directory (or drive), that would be a simpler script to write and customize, but it would also take longer to run, and there are already some nice graphical file comparison utilities that will do that.
Of course even using a hash to check the full contents of specific files doesn't guarantee that OTHER files in your backup are intact. PS1, read the comments above the $FileComparisonPairs variable to customize the paths of the file pairs you'd like to compare to your liking, and then run the script in PowerShell Console or PowerShell ISE - no parameters required. Change the extension on the attached file to. If not, I'll still have had a bit of fun writing it. If you want it when I'm done, it's yours. UPDATE: I'm just going to do this anyway. Might be a nice scripting hackathon task for me.
PowerShell even has a Get-FileHash cmdlet built in, so it would simply be a question of writing the "framework" to define the canary files and then compare results. If you're really worried about the integrity of your backups, I would probably even be willing to write an example script that does this for you to modify as needed based on the paths to your canary files and such.
If you want efficient and PROPER spot checks of files in your backups, I would recommend that you set up a script that will take a list of "canary files", calculate the hashes of those files at the original source location on your PC, then calculate the hashes of those same files in the backup you've decided to mount at any given time, and then either tell you they all matched each other or throw a warning if that's not the case. This is also why simply opening a document and skimming through it isn't a great test. It will just establish that the particular text string you searched was still found in there.

So my question is, is there a way to check the integrity of files on my computer and identify any that are corrupt before I perform my next backup?Įven if you resolve that issue, you'll still have the reality that finding those text strings won't actually establish that the PDF is NOT corrupt. In the meantime, the whole process of backing up is being wasted on those files, which might be useless. I need to know what they are and see if I can find any reason for the corruption, and also go back in my backup archives to hopefully find and restore good copies of them. There should not be any restricted files in this tree, so it's telling me I've got five corrupt files in there. The tree has many thousands of files and the search found two instances, but also reported "Search has skipped 5 files because either these files are corrupt or you don't have permission to open them." That's troubling and the message is not helpful without stating the filespecs of the skipped files. I did an advanced search in Adobe Acrobat, looking for all instances of a particular text string in a folder tree. This question is not specific to Reflect, but is more general about protecting the integrity of backups.
