Why, when I install programs on the C drive (Windows 7), much more space is lost than the program itself weighs after installation?

Question

Computers

For example, a browser, a folder with an installed browser weighs more than 100 mb., And almost 500 mb disappears. Yes, any, even a small program, such as music. player, etc., when installed, snaps from 500 mb to 1 GB. Where does this place go?! Surely this is all garbage, where can I clean it up?

Answer 1

I will expand SergeySL's answer a little :
almost every program that you install, in addition to the installation directory, also creates a working one, since users without appropriate rights cannot write to the installation directory. The worker, respectively, is created in the user profile, and the specific user who launched the program can read and write session data.
Evaluate the space occupied by your profile before and after installing the program - I'm sure you will find your missing megabytes.
However, about "Surely it's all rubbish" - if every evening at work they take away and throw away all the results of your work, how efficiently will you work?
And if the program also stores settings, or, as in the case above, the browser, plugins, its work may not be possible after such a "cleaning".
So stop being petty, start using only the "disk cleanup" utility built into the system, which will really delete data you don't need (the "clean up system files" checkbox should be used with caution) and start worrying if after cleaning the disk with the built-in utility you have little space left .

Answer 2

In addition to executable files, there is data. For example, the browser has a log, cache and plugins. All this economy is stored in the user profile, which is located on the C: drive by default.

Answer 3

The magazine and the cache are filled when you use the browser, aren't they? But when you just installed the browser, these are empty folders. In any case, they disappear, not just 100 mb, but quite tangible numbers, from 500 to 1 GB. This is clearly not normal. A clean only reinstalled axis, 45 gigs free on disk C, every little thing such as a browser, archiver, etc. is installed, which weighs megabytes, and there are already 40 GB on the disk.

Answer 4

The previous speakers forgot to mention that almost any distribution is a compressed file. When installing any program, it is unpacked into the temporary directory of the current user and, if it is not cleaned, remains with us forever.
Also, when installing some programs (for example, avast), "snapshots" of the OS state are taken (to which, if there is a jamb in the installation, you can roll back). And he takes his place too.
Well, 500-1000MB when installing the player, you turned it down. I don't believe in these numbers. In MSOffice - quite and even more.

Answer 5

CCleaner is an assistant, but not a panacea, WinToolNet, TuneUp - help, be sure to configure, well, head and hands to boot, and you can keep both HDD and SSD in order. Well, monthly cleaning in the system will not hurt.
