Looking for a search string to find corrupt files

[Grumpy John]

I recently had reason to do a clean install of windows. Initially this did not concern me as a regularly do a backup of my system files and C: drive using Acronis True Image. Unfortunately all the files Acronis restored corrupted extensions, a tilde (~) followed by eight random alpha/numeric characters (see attached screenshot), so I had to reinstall all my programs manually.
The issue is I now have a computer full of useless files, I have managed to find and delete a few thousand files using Everything and search for extensions with a tilde. I have managed to find and delete most of the common extensions such as .exe, .wav .dll etc. but there are still many files to remove.
I need help creating a search string to look for files ending with a ~ and eight random alpha/numeric characters.

Please try the following search:

regex:~[a-z0-9]{8}$

regex:

= enable regular expressions

~

= match a literal ~

[a-z0-9]

= match a-z, A-Z, or 0-9

{8}

= match the previous element 8 times

$

= match the end of the filename

Thank you, that search string worked perfectly.
