![]() The issue occurs because a ZIP archive may include a benign file (such as an ordinary. It is related to an RCE vulnerability in WinRAR before version 6.23. You might think "Well, why not just delete the old backup and make a new one which has the files you want?" That's fine until you're dealing with literally terabytes of data, at which point I'm looking at over a day's worth of transfers that I could avoid by a WinRAR-like sync feature.On 23 August 2023, NIST disclosed a critical RCE vulnerability CVE-2023-38831. Now when you go to re-back-up you still have the unwanted pictures remaining in the old backup, so you can't just copy-paste over it. Then you finally got around to deleting the ones you don't want to bother keeping. Think, for example, of a folder full of pictures which you've backed up. I have to manually sift through them and delete the old stuff.Īnd that happens a lot. That's one thing I've always found frustrating when just copy-pasting folders in Windows to back them up. The problem is, if I just use Windows Explorer for this purpose, it won't remove the old files that I've since deleted (A and B, in the above example). WinRAR's sync setting is the only thing I know of that can do that. ![]() ![]() So, like, if I have files A, B, and C in an archive and I move files C, and D into that archive, it will delete A and B, update C to the newer version, and add D. files present in destination but not source are deleted Thanks, glad it wasn't a problem on my end.īut I'd really like to be able to do what WinRAR's "Synchronize" setting does, whereby: If so, someone please explain what's going on! For all I know, this is normal behaviour. I've used this exact installation of WinRAR for literally years and have never encountered any other issues of any sort whatsoever. What that fancy thing is that it is doing I do not know, since as I said the progress window is just perpetually stuck at nothing. Yes, I get it, a 16GB archive is huge, but since it's uncompressed WinRAR ought to be functioning like a simple folder, for all intents and purposes, but for some reason it thinks it must do something fancy before adding a new file to an archive. change.Īgain, and I cannot stress this enough, the archive is uncompressed and it's unencrypted. It is not frozen I can interact with the progress window. It doesn't increase from 0% it doesn't say what it's doing it doesn't go through a list of files it doesn't give time estimations literally not a single pixel changes on the progress window until the update is complete. What's worse, the progress window that appears when it's (ostensibly) trying to update the archive is blank and stuck. To troubleshoot, I have tried creating an archive that is set to "Add & Update" (where it adds new files and updates existing ones only if you're adding more recent versions) as well as an archive that is set to "Synchronize" (where it adds new files, deletes old files that aren't in the new batch, and updates identical ones) and this issue persists regardless. Given the time this takes, I'd be more efficient to just create a brand new archive each time I want to add a single little file. Even if it's a blank text document I'm adding. However, whenever I try to add a new file to the archive (clicking-and-dragging the new file onto the archive in Windows Explorer), it takes like 2-3 times longer just to add that one damn file to the archive. It's essentially making copies of the files, and that takes time. It takes about 2 minutes for WinRAR to create this archive. For example, I have a 16 gigabyte RAR5 archive (set to storage, so there's no compression whatsoever) with 476 files in it to which I would like to add additional new files in the future.
