Strange files

[Smurre]

Hi there

Ive received a folder from a friend called "Win" in it there are a lot of files with the extension of .cab
What he wanted me to do is to check these files for specific lost items.

Many of them popup and error once clicked, and some have strange extensions added to their regular extension
like example myworddocument.docx_1063

Ive attached a picture on how the folder looks, and in these rar files there are many files like dlls, docs etc some does not have any extention

How would i be able to check these files?

Cab files are normally a compressed windows archive but can be opened with winrar you would need to open each one or extract the files to find what you want

Ive opened some one by one but they are strange, some can be fixed by removing extentions, and some folders says that they are corrupted and it's not possible to open.

Others i don't know what they mean they are letters and numbers etc.
