How do i free disk space on my macbook air

Is there a simple way to find and delete duplicated files and folders.I need to free up much needed disk space,
or there an app that will do it for me ?

Well, iTunes is a start. It duplicates your songs. (at least with me) try looking for the duplicates and deleting them. Second, iPhoto is the DEVIL!
I have a MBP mid-2010 with 250g hard drive, and i freed 30g of space cleaning out duplicate pics that iPhoto makes. There is another 10 I have an option of cleaning, but those are very important to me, so I chose not to.
That's about it.
Btw, check your applications folder and delete anything uneccesary.

You need to change the premise of your SSD use.
see here:
Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

How do I free up disk space on my MacBook Air

Hi,
I have a MacBook Air with a 128GB disk. I recently noticed that I seemed to be using up 74% of the disk capacity so thought I would try and remove some old video files from iTunes. When deleting the files I was prompted to remove the files from the file system which I did. I then empted the trash. But that seems to have very little impact on the disk space used. Considering I must have deleted about 20-30GB of files I would have expected the disk usage to come down a fair bit (I have a 128GB SSD).
Any idea how I can get my disk usage back down?
Thanks
Andy

My macbook air hd is full after installing windows, how I could free disk space?

My macbook air only has 25GB left of HD after I did install parallels and windows to use the machine at work, how I could release some space in the HD without uninstall windows and parallels?

Hi Laiwin,
What did you delete? Did you by any chance delete anything out of the /Library or /System folder off the root level of the drive? Probably the best option is startup the computer and then immediately hit Command + V. This will boot into Verbos mode. When does the boot process stop? What does it say? This will help tell us where it is failing in the boot process.

No free disk space on my Macbook Pro- why?

Hi, i'm having a lot of trouble trying to free up disk space on my mac!
I have 120g HD with 8G RAM. I'm using OS X 10.8.5
Disk Usage on Activity Monitor says i have used 110.29G and only 10.18G free, which i find ridiculous! I have backed up my computer with an external hard drive, have deleted all of my unused apps (like Photoshop and some Microsoft office programs), movies, work, and most of my photos to free up space, leaving only photos, music and a few small word files here and there on my computer, yet i still have no space!
'About this mac' shows 62.97G of 'other' storage being used.. what could this be??
I have used apps like Trash It, CleanGenius and AppTrap to free space, but nothing seems to be working! The app CleanGenius enabled me to get rid of duplicate files and i managed to get 17GB free, but after i restarted my computer it went back down to 10GB! Why?!
On Disk Utility i have used the verify disk permissions, repair disk permissions, and verify disk functions but to be honest i don't think it made any difference.
I have used terminal to free cache's and clear the sleep-mode file that the mac makes.
Any suggestions would be fantastic as i don't understand why i still don't have any space!! I've been trying for weeks! Fr
Please help!!

How can I permantely delete photos from iPhoto in order to free up space on my MacBook Air?

I am trying to delete photos (which I have backed up on an external drive) from my MacBook Air in order to free up storage space. When I simply drag the photos into the trash and empty, I see no difference in the amount of storage. I also read somewhere that they are also stored in iPhoto, so I have tried to delete them in small batches, only to return to the trash bin and find that the remaining (undeleted) ones are missing. What's going on with this?
I have a MacBook Air (late 2010)

Are you aware that iPhoto has its own trash area? Find it on the left sidebar. Go there and empty the iPhoto trash.

Disk space usage on MacBook Air 256 GB

I have a MacBook Air 256 GB version (summer 2011). I only have abot 15 GB stored under my personal data and about 30 GB on a partition for Fusion under which Windows 7 is installed. Other major applications are MS Office 2011, nothing else much, other than what came with the laptop. I've cleaned the browser cache.
However the system information shows only 10 GB free on the Serial ATA; where do I find the files that are clogging up the disc? With files mentioned as above, I would expect at least 150 GB to be free.
Thanks!

I'm still betting on the Time Machine backups being the issue. Apple sometimes "adjusts" reported free space to try and remove this space, though I've seen it get (temporarily) fouled up about this number. So, for instance, Finder does not count such space as used, but Disk Utility will show it as used.
Those backups are written to "/.MobileBackups" which (kind of) shows up as the "MobileBackups" drive you will see from time to time. Although items are written out to it and some deletion compression takes place, like your external Time Machine the general rule is that this thing will continue to grow until it (eventually) fills all available space. That is by design.
The MobileBackups disk you see in OmniDiskSweeper is the mounted version, and it doesn't appear you will get useful information if you "size" that volume. However I believe you can get the "real" size of the MobileBackups from a couple of places.
Officially, About This Mac->More Information and then Storage will tell you about the backups on your flash drive. That's *usually* correct, though I've seen it get lost on the machine I'm writing this on. I suspect that's because the machine had been set up using Migration Assistance from a MacBook Pro that had been running Lion for a while and some of that information may have "tainted" the starting point. Now the system appears to have finally figured out the real space used :-) .
I'm not sure it's more reliable (since now everything appears to work fine), but you might also get some information if .MobileBackups is involved by running the command in Terminal to show the size of that directly (Finder won't show because only root has permission to look at it).
I first fired up Terminal to get a command prompt. From that prompt I entered the following:
sudo du -sk /.MobileBackups
You will be asked for your password to authorize the command, but by the Terminal (not the standard OSX dialog).
When it ran (took a short time) it output the following:
2728912
/.MobileBackups
Which basically agrees with the 2.8GB of backups that About This Mac's More Information screen comes up with now. And which Finder totally ignores and treats as not used.
If your drive has as much free space as you expect it should have and either you've had the machine for a while, or you've downloaded and deleted a buch of videos in a directory that's not excluded from Time Machine's backup routines, I could see those "there but not really" files (at least as OSX seems to view them) easily growing to be a pretty good size. As I noted, if this is the problem OSX will kick parts of that backup off the drive as more space is needed--it's holding them there "just in case" you might want to restore them.
Have you actually had OSX complain about not having enough free space on the boot drive?
What I have found with Lion is that trying to reconcile various utilities views of free drive space can quickly drive you crazy :-) . The cause always seem to involve accounting for that mobile version of Time Machine backups.

How do i create disc space on a macbook air?

I have been trying to download photos. Have been messing around with icloud and then had iphotos update. Now I keep getting messages that I don't have enough disc space. Can't update any apps. Becoming paralyzed. How do I make space. What can be deleted? HELP

Backup your system and files to drive #1
Off-load files to drive #2
MBA internal drive is not likely to be user upgradable but that would be best solution.
