Ram problem

[q7x]

tinycore load in ram. after copy file ( for example 100 MB) into hard disk (/mnt/hda1) memory used = x + 100 MB
is there any method for copy file into hard disk and not use ram capacity.

How do you measure RAM usage?

size of backup.tar : 602 MB

before copy backup

free

cd /mnt/hda1/
cp backup.tar backup2.tar

This is normal, in a LINUX system usually you see low free memory size with command 'free'. After some use you can see increased number of buffer; it is not a lost memory, just allocated and will be reused when needed.

Better to use 'df -h' command and look for tmpfs available space mounted on / before and after.
