Long file names in C:\windows containing WiseCustomCalla.dll??

[frozenreads]

I have noticed I have a number of long (looks like hex folders) file names contained in my C:\windows directory each containing a file WiseCustomCalla.dll. I was just curious as to what they were. I assume its some lazy install software leaving things behind. Can anyone confirm this and are they safe to delete?

Those look like leftover files which should have been deleted after something was installed. They can probably be deleted, but to be safe I would move them to a separate folder and leave them there for a few days just to make sure something doesn't need them. Try making a folder, give it a name you'll remember, then cut/paste them over. If nothing goes amiss after a few days, delete the folder.

Thank you you for the informative and swift response, I know that Wise produce an installer so it looks like something left behind.
