so what is a file system which are the most important characteristics
and which are the most popular out of them let's get started
hello everyone really nice to meet you michael with recovery and this is the youtube channel
of one of the most popular and effective data recovery solutions what we usually do is to
present you easy to follow and easy to implement practical data recovery solutions today's episode
is going to be a bit different because we're going to talk about one of these things that
many people don't really understand well but we're somehow engaged each and every moment when we are
accessing some kind of data namely that's the file system structure definition and features
most likely you've heard the term file systems but you're sort of unaware of how exactly they work
which are their most important characteristics and generally how to troubleshoot them and the more
we know the greater the chances are that we might recover some accidentally deleted or damaged files
so let's not waste any further time get subscribed to the channel and let's get started with the
topic now coming from definition perspective a file system and maybe to put it into simple words
it is a method that a computing system is using in order to manage store and access files the
file system handles everything right from naming the file to deciding its logical data structure
it's also responsible for retrieving the data from a particular file basically the file systems allow
us to control the data which is stored on our drives or whatever the storage we use could be
hard disk drive and ssd flash storage micro sd card and many many others in most cases the file
system allows us to manipulate these files in the way we want as long as it is supported by the file
system like copying moving renaming deleting etc etc so in short yeah this would be the part of the
operating system which is allowing us to handle and manage the files which are stored on the
drives this leads us to the next important characteristic and that would be the type
of the file system it's a fact that most different operating systems support different variety of
file systems and it could be that for instance if you use an apple device and they have their
own proprietary apple file system it wouldn't be accessible or readable on a windows workstation
so how all of that really works well you could consider the file system as an index
for all the data which is stored on a storage device the file system specifies
the naming structure and the rules to name different files some file structures are case
sensitive in nature which means that you can't use upper case characters to the file name the
file system also defines the character length of a file while naming the files you can't go beyond
the specified character limit otherwise the file system automatically triggers an error message
apart from the basic information the file system also holds advanced details such as the size of
the file its attributes and its target location all these details are starting the metadata which
is a separate block on the storage devices your system uses to fetch data from the file this
metadata also stores the directory arrow key to pinpoint the exact location of a particular file
on the storage device now coming to the types of the file systems and as we mentioned a bit
earlier certain operating system have access to certain file system types some oss could support
a wider variety of file systems some not really i guess we're going to start with the most popular
one and that's related to the microsoft windows operating system it's called fat so popular fat
file system it's probably one of the oldest file systems which are supported by multiple
operating systems including windows f80 stands for file allocation table in many situations a
file is broken down into multiple sections that are scattered across the hard drive of a system
the fat file system is responsible for keeping a track of these sections to make it easier for the
system to fetch the data when requested ideally the file system supports up to 8 characters and
the name should always begin with an alphanumeric character ok going further with fat32 or 532
it's the advanced version of the original fat file system so it's an improvement and
it's mostly targeted at customers running windows 2000 and older meaning that you can still find it
well supported with some computers that are being utilizing a newer and fresher versions of windows
it's very suitable for devices coming from a size of 512 megabytes up to 2 terabytes and they
do support a much greater amount of files to be stored fab32 makes disk utilization more effective
as it can access files more rapidly across different storage devices continuing with ntfs
and i remember it's something that was presented for the first time with windows xp and there was
the way to upgrade and actually convert the file system from fat32 to ntfs but going backwards
was a no-go anyhow so with ntfs everything is a lot more advanced and the file system is no longer
case sensitive meaning that as a user you have the liberty to name the files the way you want
next apfs that's the apple file system it's something that the company has developed back
in 2016 in order to strengthen its position and to also improve the performance on its
various devices but the thing is it only support it on i devices on macbooks iphone
ipod etc the thing is that if you format a flash drive into apfs it's only going to be
accessible by operating systems which are capable freeing apfs so understand ios or mac os therefore
in order to read and write data to the very same flash drive and this to be accessible by
another operating system you have to reformat the drive into ntfs or fat32 kind of awkward
since we talk about apple here's something else you might come across hfs plus it's another
invention and development by the cupertino-based company something they presented back in 1998.
it was considered a revolution as it replaced the conventional hierarchical file system
used by apple computers hfs plus enhanced the performance and made file accessibility
more rapid even in 1998 hfs plus supported up to 255 character limits so this concludes our journey
across the most popular file systems of course there are a lot more and we've tried to narrow
down the most popular ones i guess you might look around for more information about ext3 and 4 which
are popular linux related file systems the best news for you is that our award-winning solution
recover it is capable of recovering damaged or accidentally deleted files from most of
the popular file systems and in the comments below you can let us know which are your favorite file
systems and why if you find this video insightful then please make sure to subscribe to our channel
i'm michael look forward to seeing you in our next practical data solution tutorial bye
