PREFETCH folder

You need to understand the purpose of the prefetch folder (C:\WINDOWS\Prefetch):

When you launch a program, it does: processing ---> disk loading ----> processing ---> disk loading, etc.

On the first launch of the program, Windows will analyze (for 10 seconds) which files the program accesses and note them in a file in the prefetch folder.

On subsequent launches, during the program's processing phases, Windows will use this information to pre-fetch the files that the program will need.
The result: a faster launch of programs.


In addition to that, the prefetch system is also active during the startup of Windows, in order to track the file loads at startup (and optimize Windows startup).

Finally, the Windows defragmenter can also use the information from the prefetch folder, to place the most used files at the beginning of the disk at startup, further improving performance.

It is unnecessary to clear this folder, as Windows limits it to 128 files anyway.

Deleting the contents of this folder will therefore only reduce Windows performance.
Disabling the prefetch function will also deprive you of the performance improvements it provides.

Hello, the work is already done, since I've run CCleaner and also Cleanup 4, the latter by clicking directly on "cleanup," without any further checks, I noticed it was still bringing in some stuff. Thank you.

No idea, it depends on what this "error correction" is.

Hi,

No, it doesn't matter at all.

"fixing the errors": simple cleaning of the registry ;-)

See you++

Practice makes perfect ;-)

And it's in "search" that we need to type C:\Windows\Prefetch?

What you must not delete will not be deleted.

Use the software I gave you, why are you trying to understand what you don't understand?!

Ah, I hadn't read it completely, not only if there's something that really shouldn't be deleted you won't be able to delete it, but also, the layout.ini file can be deleted without any problem.

It's important to understand what the prefetch folder (C:\WINDOWS\Prefetch) is for:

When you launch a program, it does: processing ---> disk loading ----> processing ---> disk loading, etc.

On the first launch of the program, Windows will analyze (for 10 seconds) which files the program accesses and notes them in a file in the prefetch folder.

During subsequent launches, at the processing phases of the program, Windows will take advantage of this to retrieve in advance the files that the program will need.
Result: Faster program launches.


In addition, the prefetch system is also active during the startup of Windows, to track the loading of files at startup (and optimize Windows startup).

Finally, the Windows defragmenter can also use the information from the prefetch folder to place the most used files at the beginning of the disk during startup, further improving performance.

It is unnecessary to purge this folder, as Windows limits it to 128 files anyway.

Deleting the contents of this folder will only reduce Windows' performance. Disabling the prefetch function will also deprive you of the performance improvements it brings.
