Freeing up hard drive space

I am trying to figure out how to free up space on the mac hard drive. If my iTunes library is backed up to an external hard drive, can I delete the library from the mac hard drive? How would I re-map iTunes so it launches from the external drive?
Next question: I store all of my photos on 2 external drives, but does the mac store a copy of the photos as I am editing them in Photoshop? Would love to understand how to clean this up, as I am down to less than 1GB of space on the mac.

How would I re-map iTunes so it launches from the external drive?
Hold down the option key while starting iTunes. Select the different library. Note, your external drive will have to be on when starting itunes in the future or else it will make an empty library on your drive.
Next question: I store all of my photos on 2 external drives, but does the mac store a copy of the photos as I am editing them in Photoshop? Would love to understand how to clean this up, as I am down to less than 1GB of space on the mac.
I don't use Photoshop but it isn't unusual for applications to make temporary buffers when editing files. I don't know if you can or would want to disable that.
1GB is seriously low. You should probably have 15+ GB free.

Hard Drive Space Dilemma!!! HELP!!!

I am maxing out my hard drive space. Every time I delete something, 5 minutes later it says Zero KB available and I didnt even save anything! I have an external hard drive, and put most of my work on there so all I have saved on this Macbook is a few songs and some essays. what the heck keeps eating all of my space without my permission and how can I get rid of it? Thank you Gurus!!!

The following info might help you free some space.
The XLab: Freeing space on your Mac OS X startup disk
The XLab: Uninstalling Applications
Use either one of these too see what is taking up the most space and what all is on your system drive.

What is taking up hard drive space?

hello.
I have a power mac (pre intel) quad core desktop running 10.5.8.
I have noticed it being very sluggish lately.
From taking 5 minutes to boot up, to browsers taking longer to launch(with the color wheel spinning longer until the browser is fully ready), to inputing text into fields in a browser window(the text gets entered a second or two after typing). Even when I open a finder window, the icons for every file, as well as the size listing of each file/folder will take like 10 seconds to start loading one at a time. I never noticed that before.
So I opened disk utility, and noticed that I have filled up 160GB out of the 233GB that this hard drive has. That seemed like a really high number.
So I added up the total size of the home folders in all 4 users on this computer, and they add up to 27GB. The system folder is 4 gigs, and the main Library folder at the top level is 51 gigs. I don't think there is anything left. That adds up to 82GBs. Where is the other 78GBs coming from?
I know I'm missing something, but I can't figure out what.
Even still, I don't know that this is the reason for my computer to act sluggish, but now I'm curious how I'm filling up so much hard drive space.
Any thoughts on finding this info out, and/or fixing the sluggish issue?
Thanks!!

On the space issue, has everybody emptied trash? You each have your own and if somebody doesn't... There's varous utilities for scanning drives for space usage. Some are free, others not. I think Omnidisksweeper is free. Search the Discussions for this subject and the others will probably be mentioned.
A few GB are kind of hidden and not accounted for, I think. Some cache files, etc.
160? I mean only 160? That's peanuts by modern standards.
Slow computer. Might start by verifying hard drive with Disk Utility. Installing and using Applejack would be good too. Are you sure everybody is logged out and didn't leave a ton of applications running in their account?
I'm too lazy to remove the old formatting from my boilerplate post on this:
*Quick checks*
Have you emptied the Trash?

Need help finding lost hard drive space on my Power Mac G4

I have a Power Mac G4 that is just about out of hard drive space. Why? I have no idea. I only have about 7 MB left of the 512 MB that came on the machine. I have backed up most pictures, documents, etc... to an external hard drive and have barely anything left on the desk top. Does anyone know what might be working 'behind the scenes' to eat up hard drive space or what I can do to gain any back? I'm not a huge 'techie' so any advice past 'empty the trash' would probably be helpful.
Thanks very much for anything you can do for me.
Tony

I believe you mean GB instead of MB when referring to hard drive size/space.
Look at these links.

What is the other category on my mac book pro for hard drive space on how do I improve on it

What is the "other" category on my mac book pro for hard drive space? I found out that it is taking a whole lot of my computer's space...how do I find what it is and optimize it?

If you need to remove files for space see The XLab FAQs and read the FAQ on freeing space on your hard drive. Also see Freeing space on your Mac OS X startup disk.
Under no circumstances should you try deleting files outside of your Home folder.

Where's my missing hard drive space?

I posted earlier about this, it may be a bit off topic but if anyone can offer a clue, I would appreciate it.
I got my win 7 upgrade and was waiting until vista started giving me headaches or the win7 service pack1 came out to upgrade...vista got me to upgrade today and I have to admit it was much less painful than i anticipated.
My question is about the missing hard drive space on my Idea center K230 on the box and on the side of the comp it claims a 640 HD (it claims in small print that up to 18gb may be used for the service partition) I questioned this when i first got it and even after deleting all the preloaded crap it was still saying 540 available out of 580GB....then I read that Lenovo has a huge partition for backup. So when I do my upgrade to win 7- 64 bit, I do a clean install and delete the smaller partition and reformat and expand the larger but before installing the new OS it says I have 596 available, so where the hell is the other 44GB of hard drive...did Lenovo rip us off and put 600GB hard drives in the K230's or is there a hidden partition still left that I cant find?
I am running everything off of my 596GB C: drive, I have my virus stuff and video card extras loaded, everything from the upgrade and 21 available patches and new drivers for most of my stuff....right now I am at at 575gb available and if i can ever find a printer driver that works I will create a backup point or disc from there, whatever win 7 allows. I never wanted the Lenovo one button back up and thought it was stupid to put a big glowing button on the keyboard that wipes your system back to when it came out of the box...I had nightmares of someone getting curious and going "what does this button do?"
.I notice I have a program files folder and a program files (x86) folder with a bunch of redundant files. what's the deal with this is Lenovo still hiding a backup program (maybe in that hidden partition?) that fills my hard drive twice as fast or is there a purpose for the file copies?
Any info on the above questions would be appreciated, and for those of you just looking for upgrade info I have good news, when you finally get your win7 upgrade disc it is the easiest windows installation ever, almost copmpletely automated, and very fast. So far the only sticking point is finding a printer driver, but I have 3 printers i can try, maybe one is supported.

Hi wise2u!
You can read all the details about how storage manufacturers use multiples of 1000 to measure disk space, and Windows reports it in multiples of 1024, and there is some overhead for Windows, or you can just use this rule of thumb from wikipedia:
A general rule of thumb to quickly convert the manufacturer's hard disk capacity to the standard Microsoft Windows formatted capacity is 0.93*capacity of HDD from manufacturer for HDDs less than a terabyte and 0.91*capacity of HDD from manufacturer for HDDs equal to or greater than 1 terabyte.
0.93 * 640GB = 595GB, which is about what you're seeing.
I don't work for Lenovo. I'm a crazy volunteer!

I have a new Windows tablet computer with limited hard drive space, and cannot transfer my itunes library to the hard drive. Can I run t media from an external hard drive? If so, how do I transfer my files?

I have a new Windows tablet computer with limited hard drive space (32 GB), and cannot transfer my itunes library to the hard drive. Can I run itunes from an external hard drive? I have tried to follow some of the directions on this site, but am having no success. Thanks.

iTunes will run fine with the media on an external drive.
However, I suggest that a tablet computer with a tiny hard drive is not ideal as the primary computer for managing an iTunes library, even a small one. If you have another machine, perhaps a big, boxy, inexpensive old desktop with a decent amount of storage, that might be a better choice.

I HAVE BEEN USING MID 2011 MACBOOK AIR 11 INCH.I AM LOSING MY HARD DRIVE SPACE WITHOUT ANY REASON.FIRST IT WAS 84.1 GB NOW IT IS 83.9 AND SLOWLY LOSING SPACE.WHY IS THAT?? PLS PLS HELP

I have macbook air mid 2011 .. Now i am losing my hard drive space without any apparent reason..I am not downloading anything not i am adding anything still that i am losing my hard drive space for no apparent reason..pls pls help..

I have never heard of a relation between the enabled state of Time Machine, and boot. Its probably coincidental.
Try booting in Safe Mode (hold down shift key, whilst booting). Then check for apllications in your Users & Groups preferences that are starting up with login. Disable all startup apps, then eanable them one at a time, booting normall. See which app is possibly hanging.
You can also try doing a Repair Permissions and Repair Disk on your startup drive. This must be done within Disk Utility when booted to your Recovery Partition. To boot to the Recovery Partition, hold down the OPTION key while booting, and select the Recovery Partition drive to boot from. Then run Disk Utility.

Running out of hard drive space---can I use my external hard drive-??

I have a 16GB iPod nano. I hope I can explain my problem well enough.
My laptop computer has the iTunes that I use for syncing my iPod. It has over 25gb of songs in it, but my problem is that it has completely run out of hard drive space, and I don't think I can delete anything else.
I have a 250 GB external hard drive that also has all my songs backed up on it, that has hard drive space left on it.
Is there a way to load new music into the external hard drive, that will sync up to the iPod when I connect it to the laptop, WITHOUT putting a copy of it into the laptop, and taking up space-?
The way it appears to me, and I may be wrong, is that there are 2 copies of eaxh song on my laptop---the one in my music folder, and then the one in the iTunes folder. Is that correct-?
OR, is there a way to remove some of the songs from the laptop, and put them into the external hard drive, but will still sync up to the iPod-?
Thanks for any help that anyone can offer, I'm desperate ~!
I'm not sure if this can be done, but I'd hate to think that I cannot put new music onto my iPod.
Thanks~!

Hello melbernai,
I think your best move would be to the move the entire iTunes library including of all of its file to your external hard drive and running your iTunes from there. You can even have it so that all newly imported music is saved to the external drive as well.
For more help on how to do this, I would check out this article on how to move and run your iTunes library from an external hard drive.

HT201250 I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them?

I had files stored on a hard drive that were not on my Mac. I used the hard drive for my first Time Machine back up, but it was not enough hard drive space to finish. Now those stored files are gone. Is there any way I can recover them? No, they were not part of previous Time Machine backups, and I have checked both the hard drive the documents were lost on and the new one that I now use for backups. Any suggestions would be helpful, as the lost files are old pictures that are gone forever. :[ Thanks!

1. Yes, if both drives are formatted as Mac OS Extended (Journaled).
2. Reformat the drives if needed, open the Time Machine pane of System Preferences, and remove the drive with the pictures from the list of items set to be excluded.

Can I connect an external hard drive to my time capsule to add virtual hard drive space?

I would like to make a 4 TB external hard drive available wirelessly on my home network. I have heard that I could connect it to my router or my Time Capsule to do this. Is this possible? Is there any special setup I need to do to enable this to work?
Additionally, I have two Macbooks in the house and have recently purchased a second Time Capsule. I would like to back up each computer to its own Time Capsule. Is there a configuration that would make this possible?
If the two Time Capsules are connected together via an ethernet cable (in extend the network mode), and one elects to back both of their computers up to the primary Time Capsule, does the primary use the secondary Time Capsule's hard drive space to continue backing up once it becomes full?
Thanks in advance for any advice you all may have for me in this situation!

How do I get more hard drive space for my Macbook Pro?

I am losing hard drive space and I don't know why? Is something writing or copying on my Macbook Pro?
Thank you...

The Hatter..This may be helpful information. I go to force suit and there is both Safari and "Safari web content not responding in red" and this may
be the problem. I delete files and I get up to 50 to 50 MB and then it goes right back down to zero with no use on my part. I made a mistake by
viewing **** on a CHatterbate site and I think that this may be the problem. How do I get rid of this virus, if that is what is happening> I ran Clam X and
it did not find anything...Thank you, again.

What is using my hard drive space on my macbook pro

Something is using all my hard drive space and I cannot figure out what. Yesterday I had 120GB and now I have 120MB free and got a disk warning. I have noticed this past week that my space has been eaten up. My Mac Book Pro is 2 months old and I have not put any big or fancy programmes on it as I am still getting used to this being my first Mac. One of the selling points for getting a Mac is I heard its programmes took a lot less space. My previous PC that I had for 2 years had a 130GB hard drive and I had 20GB free when I gave it away. I cannot believe I have used all my 500GB hard drive space when I have only installed a few programmes on this one such as Notebook, Pages, and some accounting software. I cannot seem to find details of where the space is being used. Please help.

"iTunes Media" file in "Previous iTunes Library" taking up 50Gb of much-needed hard drive space. Can this be safely deleted?

Hi everyone,
My 3.5 year old 15" Macbook Pro is running out of hard drive space, so I have been trying to clean out some of the dross. I recently found that there is a file called "Previous iTunes Library" in my iTunes folder that is taking up approximately 50Gb of space. I would love to delete this folder and reclaim the space, but I am not sure what it is or where it came from, and I don't want to lose music files accidentally. Can someone tell me (1) what this folder is and (2) if I can safely delete it?
Here is a screenshot of these folders and their sizes:
Thanks for the help!

Hello facetious1212,
Take a look at this part of the article named iTunes: What are the iTunes library files? Found here http://support.apple.com/kb/ht1660.
Tip: New versions of iTunes sometimes include enhancements to the iTunes library. When you open the new version of iTunes, iTunes upgrades your existing library to the new format and places a copy of the old library in the Previous Libraries folder. If everything goes fine during your upgrade to the latest version of iTunes, you can delete the older iTunes Library files.
All the very best,
Sterling
