Improve Explorer File Copy Cache Size

[The One]

When I copy large files explorer *seems* to read x MB of the file, then
write x MB of the file.

This is OK when copying between different media/hdd, but a problem when
copying between different partitions of the same hard disk.

Is there any registry tweak to adjust the value of x to a bigger number? I
have 3 gigs of RAM and would like to utilise them.

Thanks.

Hi,

The amount of installed ram is not the issue here, what is the issue is the
copy process. Is the target partition using FAT32 or NTFS?

Hello, I understand that RAM is not a issue, but it will sure help if
Explorer can copy the file(s) to RAM first, then write to the destination.

the source/destination varies, from FAT16,Fat32 to NTFS.

Hi,

Understand that the FAT32 file system has a size limit of 4GB, so if the
file is larger than that you cannot make the transfer. It wouldn't matter if
the entire file were written to ram first or not.

I know that .. what I am suggesting is to make the File Copy process faster
by copying the whole file to RAM first, then writing it to the destination.

Because the HDD cannot access two places at one time, when I make a copy of
a 1GB file in the same folder, explorer copies X MB to RAM first, then
writes to the HDD, then reads the next X MB again .. My initial post is to
ask how to increase the value of X.

Thanks for the help.

Hi,

I understand what you're asking, but you are thinking in linear terms and
that is not how a processor works - at least not in the simplest definition.
It doesn't do one task to completion and then move to the next, but rather
does several parts of different tasks in rapid succession. It wouldn't
matter how much is copied to ram, as the processor works in time slices for
each process, and the time between each slice is plenty to allow for ram to
be loaded with new information (remember, with dma devices do not have to go
through the processor to load data into memory). Changing x is not the
solution you think it is, you'd be better off checking out background
processes.
