How to uninstall apps?

Is there a way to uninstall multimedia applications, or business?
I can't find how to locate e.g. mplayer, gnumeric etc, in package manager.

Try the utility "Remove builtin packages".

If not there, you're stuck with manual uninstall.

I just had this issue recently with Firefox: viewtopic.php?p=7779&i=1

utility Remove builtin packages.

Be very careful of what you do with this program.

Something you uninstall may be used by some other program.
Select only a known named program that is listed in the main menu.

If you uninstalled all the programs that come installed in Puppy.
You would only free up about 150MB of space.

Remove builtin packages does not actually uninstall anything.
It white lists it, so it is no longer seen by the file system.
A remaster of the Puppy version iso is the only way to not have it in the Puppy version.
Why?
Because the Puppy version main sfs is never loaded so it can be written to. Only read from.
So, you can never remove from it by uninstalling something.
You must remaster it, leaving out what you did with Remove builtin packages.

Thx!
I'll try out with both ways/solutions.

dunno if I'm right with how the puppy works:

Removing some programs(e.g. mulitmedia applications) with the utility remove built-in packages, does it actually remove from loadin into memory, at the system start?
I've had initial ram usage with 330, after I instlled chromium it goes to 380,
so does it mean if keeping installing programs (e.g. openoffice), the intial memory usage,
after OS start, is increasing.

I've 1 gb ram, so I thougt to bring down initial ram usage to 250-200 mb ram.

Yes.

after I instlled chrome it goes to 380,

That seems to indicate Chrome is loading something that is always running.
Example:
why do i have 4 software reporting tools running using up 40% of my cpu

Installs of added programs go into the save file/folder.
The save is only mounted into the file system, not loaded into RAM.
Programs in the save do not load into RAM, until you start running the program.

@bigpup why for example will my 2gb ram machine provide 1gb of volatile storage, yet the task manager still reports I have 2gb of ram?

Related understanding: Does storing your favorite browser in a pupsave save session ram vs installing it from .deb or .pet each session?

Live, the installation uses up storage capacity, and that strongly appears to be ram.

[bigpup]

A live session of Puppy, not using a save, is running in pupmode 5.
It uses a set aside amount of ram, as a ram disk, to act as a storage device, when you install something.
What you install goes into the ram disk.
So, yes it uses up ram.

Well you still have 2GB of RAM.
What is being done with it is constantly changing.
It is normal for running in pupmode 5 to take half the RAM and set it aside for a RAM disk. (the highest amount it will ever use)
However, the amount that has not yet been used, can be released for normal RAM usage, if the demand is high enough.
There is a lot of automatically, under the hood stuff, going on with controlling RAM usage.
All kinds of factors are constantly evaluated and adjustments made.
Constantly changing balancing act.

With RAM usage. A amount can be flagged to be used for say cache, buffers, Puppy save ram disk.
But it is still free memory, to grab and use, if it is really needed for a higher priority function. (run a program)

[JASpup]

I understand what you wrote, but it's difficult to grasp in concrete terms.

The necessity would be, a) falsely reported available ram upon ramdisk usage, & b) an inherently performance-limited machine with a full ramdisk.

[bigpup]

RAM usage and control of it, is one of those things that will just give you a headache, if you think about it too much.
Just know that what needs to be done is automatically being controlled.

Reporting programs are only giving you info for a specific point in time.
