[Solved] Using Bleach Bit?

Post by tnt2 »

I have a quick question about using Bleach Bit.
When I run the "Free disk space" utility, it creates a rather large folder in my "Home" section of my PC.
Is it alright to delete these folders?

I have never used it, but this guide says to never use it.

About once every week or two, there is somebody on the forums wanting to know how to fix the damage bleachbit did to their system. You have been warned.

BleachBit should be kicked out of the official software sources. :x

Used Bleach Bit for years, no problems. Pljotr seems to be a Mint Forum insider with conservative views.

No secure delete on Linux Mint OK. Hackproof ?

Bleachbit is safe to use, if is correctly configured. I use it almost everyday with no issues. In my opinion (as a user) Bleachbit must not be feared, is a good and useful tool to keep clean the system and free space on the disk (or SSD).

There is absolutely no need for bleach bit on Linux. It only exists to satisfy Windows users who feel a need to "clean" their computer. A legitimate concern in Windows, with that beast called the registry - but not in Linux. Linux already has cron jobs that run daily, weekly, and monthly to automatically "clean" the system of stale log files, caches, temp files and such. Bleach bit is nothing more than a Windows user's crutch, and a dangerous one at that.

Ever heard of 'dd if=/dev/zero ...' ?

First: thanks richyrich for actually answering my question. I was able to delete the files....they were huge!!
Also, thanks everyone else for replying.
I checked out the links you provided and found them very informative.
I have decided to remove Bleach Bit from my system.
Often being a danger to myself and others as far a my past experience with computer software, etc., I decided it may not be a safe bet for me.

Linking to "Google" sites on Mint ? Read this splurge before.

As regards 'dd if=/dev/zero ...' ?, very simple overwrite of 0's, not much better than Windows. EXT 4 journals record far more.

Bleach bit does the same! Bleach bit won't touch the journaling part of the fs, either. With dd, you can zero a partition or entire drive, including the journal.
BleachBit's secure erase method is a single pass with zeros, so why doesn't BleachBit use the Gutmann-35 method? The Guttman secure deletion method gives some people a false sense of security. A long time ago (in the technology timeline) the 35-pass Gutmann method was designed for MFM/RLL hard disk drives. My last computer to include a MFM hard drive was purchased in 1989. Time has passed and technology has changed. Today's PATA/IDE and SATA hard drives are much more dense, and NIST, the NSA, and other experts now agree that a single pass to overwrite data is sufficient.

So Mint has no secure erase and none is required, hackproof and ironclad ? Despite recent booboos, all is OK, bugger this for a game of dominoes, noving on.
