Windows 10: Checking that my files are not corrupt

When I make a backup of my USB stick folder that has a few thousand personal files in it, I look at the backup I have just made and look at the folder properties and make sure the backup folder size is identical in bytes as to the original. Is this a good way to make sure the files copied over correctly? Would Windows notice if a file size is different during copying from the displayed file size in properties, e.g. due to the file being corrupt, and update the file size in properties, or would Windows only realise the different file size and update the properties after the file is opened?

Corrupted file RAR

If the archive has been created using WinRAR, why don't you try WinRAR itself? It has a built-in repair feature for repairing corrupted archive (ZIP as well as RAR). Follow the steps given below:

• Open WinRAR application in your system.
• Now click on File tab > Open or simply press Ctrl+O.
• A small window "Find Archive" will pop up. Locate the corrupt RAR archive from your system directory and select it.
• Now click Open button.
• Click Tools tab > Repair archive or simply press Alt+R.
• Again a small window "Repairing File name.rar" will pop up.
• Now click Browse to select a location to save the repaired archive.
• Check the box "Treat the corrupt archive as RAR" and click OK.
• WinRAR will start repairing of corrupt RAR archive. Once it gets completed click Close.

I hope the above steps will help you repair the corrupted RAR archive.

Thanks.
