Win 7 user here. I have a bunch of photos and videos that I want to compress to save space. I thought about adding them all to a 7zip file.
But is it possible to open the 7zip file and see thumbnails of all files inside, without decompressing them first? I tried this with Winrar but it didn't work.
I know I can make a separate folder with the thumbnails of all files and store it there, but I was looking for a simpler work around.
Thanks for any ideas!
I agree, unless OP wants to store RAW images or the video equivalent, compression will probably not make a noticeable difference. – cascer1 – 2016-09-21T11:36:53.807
You're right, even though a regular zip folder saved me some space (around 5%), it's just not enough to justify the hassle. I'm probably better off leaving it like it is. Thanks for the tip and for the answer! – flen – 2016-09-21T13:08:36.540
No, the idea of a zip file is to have a directory which behaves like a file for all purposes except exploration. – 7vujy0f0hy – 2017-05-10T18:47:24.217
@7vujy0f0hy I'm really not sure where you got that idea. It might be a scenario for you but the format is meant to compress files. It's a solid stream, it will handle significantly different from a directory. While you're correct that you might do minor changes in a fast way the usual implementations decompress and compress on changes in order to free up the space and optimize the compression.

But what I meant is that it's still a continues filestream (hence you handle it as a file) with the directory at the end of it. Even if you're able to easily list the content of a zip to actually make the data readable to "non zip aware" applications you need to extract it as it is not just part of the filesystem (in most cases).
