Help Super odd file sizes

My Galaxy S4 Play edition has gotten a bit slow. While I do have a good number of apps on the phone, I was still surprised to see only 1.4GB free space on internal storage. So I fired up DiskUsage and found really odd size apk files. Can anyone explain the file sizes? I have attached the screenshots.

While I have a few books in Kindle app, they are certainly not of 131mb and apk is 85mb? What made apk to swell up to 85mb?


Chrome apk, 73mb?


Facebook apk 171mb?


Skype, Amazon apk, more than 50mb?


You got the idea. Whats going on here?

Thanks in advance.

Edit: I checked the app storage sticky, but I am not very clear on that, hence keeping the question as it is.
Storage Truth screenshot, if it helps in addition.

Actually, I did clear the data, but its still 151mb.
(there is a typo in OP, it was 151 even then, I typed 171)

 
Hi

The apk files that you see in diskstorage (which I consider to be a great app) are not the files that you downloaded from playstore when installing the app. Those original downloads are saved in /data/apps which you (and diskstorage) cannot see unless your phone is rooted. The bigger files are .apk files (actually .zip files by another name) which contain the expanded working files and libraries needed for actually running the app. I think they get bigger when you select options in an app, install extra (google) accounts etc. Several of the same apps on my phones are bigger than you are seeing... If you really want to see whats in them, copy them to a pc, rename from .apk to .zip and unzip them.
