The Dolphin have the ability to compress /uncompress file, and I find that if I need to compress a big file ,to several packages, I can't do it in Dolphin, in fact I don't know how to do it in linux, so I think the compress tool should provide some configure to user, so they can compress in several packages.

Have you tried using Ark?
Can you please provide more details on the precise error messages or problems you are facing compressing large files?

Native linux file systems are more than capable of storing very large files so this should not be a problem.

For example, I need to compress the file 'webOS-V1.0.pdf' file to .rar format, and need every generated .rar file should no more than 500kb, in the Ark ,there is no configure to let me do like this.

you can do this with the rar command using the volume size switch: v<size>[k,b] Create volumes with size=<size>*1000 [*1024, *1]

so for your example it would be

Code: Select all

rar a -v500k webOS-V1.0.rar webOS-V1.0.pdf

Yes, maybe I can try to read the code to design a UI interface, thanks .

you could do this with a service menu

this is basically copied verbatim and adjusted from something that's on my system and neither tested nor guaranteed

service menu (placed in ~/.kde/share/kde4/services/ServiceMenus:

Code: Select all

[Desktop Action compress_RAR-500k-chunks]
Exec=~/bin/compress_RAR-500k-chunks.sh %U
Icon=application-x-archive
Name=Compress to rar in 500k chunks

compression script (placed in ~/bin/compress_RAR-500k-chunks.sh )

Code: Select all

#!/bin/bash

dir=$(dirname "$1")

cd "$dir"
files=""
y="0"

for i in "$@";do
file=$(basename "$i")
files="$files"" \"""$file""\""
y=$((y+1))
done

if [ $y -gt 1 ];then
name=$(archname_dialog.sh "$getname")
  if [ "$name" == "" ];then
  compress_cancel_dialog.sh
  exit
  fi
else
name=$(basename "$1")
fi

archname="$name"".rar"
exec="rar a -v500k -o+ ""\"$archname\"""$files"

overw="0"

if ( [ -d "$archname" ] || [ -f "$archname" ] ); then
echo "file/folder exists"
overw=$(overwrite_compress_dialog.sh "$ow")
fi
echo $overw

if [ "$overw" == "0" ];then
echo "$exec" > .comparchive.sh && chmod a=r+w+x .comparchive.sh
sh .comparchive.sh && rm .comparchive.sh
