OS X V10.7 Lion :: Processing Large Files On Mac?
Jun 5, 2012
I need to process large files (few GB) from a measurement. The data files contain lists of measured events.I process them event by event and the result is relatively small and does not occupy much memory.The problem I am facing is that Lion "thinks" that I want to use the large data files later again and puts them into cache (inactive memory). The inactive memory is growing during the reading of the datafiles up to a point where the whole memory is full (8GB on MacBook Pro mid 2010) and it starts swapping a lot. That of course slows down the computer considerably including the process that reads the data.
If I run "purge" command in Terminal, the inactive memory is cleared and it starts to be more responsive again. The question is: is there any way how to prevent Lion to start pushing running programs from memory into the swap on cost of useless harddrive cache?Â

I have files that were created in Apple Works and Word Perfect for Mac that need to be translated. Mac Link does not make a version for Lion. What else can I use to translate these files?

I have a folder with about 600 funny photos that I randomly saved. And you know how pictures you save from sites have random long numbers as names? Well here is what I want: I want to know if there is a way to automatically number all the photos starting from 1. Any way to do it that is already in Mac OS X Lion 10.7.3 or recommend some software.

I have several hundred word processing files I prepared in MS WORD. I moved the folders containing this files from my old computer to my new iMac. Every time I try to open one of these files, I see a box on the screen saying the file cannot be opened.
This is true when I try to use MS WORD for mac, when I try Pages, and when I try other word processors.
I suspect some sort of permissions need to be set for the folders or the files. I hope it can be done in "bulk"

I recently discovered, after running Disk Inventory X, some really fat files in my Library. I haven't touched them, as I read on another forum that it could be dangerous but is there anything I can do to get rid of them? I thought maybe they were left there after a recent Time Machine backup because I read that happening to someone else in another forum...
I've attached screenshots (I think) of the two biggest files.

I'm envisioning a scenario where users can drop multi-page, image based PDF files into a shared folder. That folder is "watched" on a OS X Lion server and new files are OCR processed and then moved to another location. My googling so far hasn't showed much promise. Most solutions I'm finding are for windows. Has anyone solved this problem yet? Currently my users are doing the processing in Adobe Acrobat X Pro by hand. It's crushing their laptops and proving to be quite inefficient.

I do a lot of work that involves advertising, photography, video editing, DVD authoring, photoshop and illustrator files. The illustrator vector files are fairly compressed but the photoshop raster files can be extremely large. Sometimes, I have someone wishing to send me a large portfolio folder, or I find I may want to send a big file to someone else. As an example, I recently had an artist send me a hi-res portfolio of his book covers to be made into a promotional DVD for comic-con. One of the CD's he sent me had the wrong pics on it, so I had to wait for the correct pics to be sent, which delayed the project several days. I can compress a single file for emailing, but can not drop the resolution as a way to minimize folder size if the file is going to be printed. I work predominantly on a mac, but many of my customers use windows based operating systems.
What is the best method for sending and receiving large digital files from a variety of customers? If I get an FTP site, can I keep one client from accessing someone else's folders? I noticed that Skype allows for file transfer... is VOIP practical for sending large files? This month's macworld made mention of a bit torrent program for such a chore. What about using a bit torrent program such as Transmission for creating a bit torrent folder for moving large files to a single customer? Are paid services available? Is a paid service the best choice? I am looking for a method that I can both send and receive these large files. It should be easy enough for a less than tech savvy customer to send me files after I give them a minimal explanation of how to do it. Preferably, it would involve no cost to a customer, and no need for them to install software.

I needed to make 40 dvd's. My burner is burnt out on my mac. I've created all the dvd's as iso files with iDVD. Now I need to transfer them to my PC that has a functioning burner. SOOOO... transferring 81.5 GB of data over a network will take days. Having said that, I'm using an unsecured network that drops out frequently. (I just moved in, it'll be weeks until the phone company can hook up my internet... we just had a hurricane and they're busy with repairs). Next idea, use a flash drive. Most of the iso files are bigger than 4Gb - so FAT32 is out. What's left?
which sounds promising, but once the files are split, how do I join them back together on my PC? Oh, and did I mention that this job is for a client and they're waiting on it. STRESS!!

I have a brand new unibody macpro which came with 10.6. I am unable to print large files onto my HP z3200 (500 mb or greater) with Photoshop CS3. I can print the from LightRoom 2.5 with no problem but would far rather print from Photoshop. HP doesn't seem to have much of a clue about this.

I have large archive files from work (each ~10-20 GB) that we'd like to just backup onto DVDs and store in a safe. Obviously, each individual file is too big to fit on a DVD (even the double layer ones). Is there a "compress and split" sort of software that could be used for this?

I recorded a movie with isight-a very long one at that-around 3 hours. When I try to play back I receive error message "The movie is not in a format that QuickTime Player understands." How to play? I have Quicktime Player 10 running from Snow Leopard. Inside the folder for the event in imovie it shows the movie file but with a zero kb size. Also has an imovie cache folder.

I'm new to Mac and not sure how to do this. I have a several large (1.5GB each) iso files that are named like this: "filename.iso.0aa", "filename.iso.0ab", "filename.iso.0ac", etc. Is there any way to join these and burn them to DVDs? I've tried S&C but it doesn't work.

When I tried to copy a large file to a new drive I got Error Code 1309 which shows I have the wrong format on the drive. Checking out Disk Utilities I see I can erase and format. I should choose Mac OS Extended, right, and when I click erase it reformats to my chosen option, correcto?

I am having another problem transferring some larger folders from my old MacBook to my new MacBook. I am trying to move some very large folders and individual files from my old Mac to my new Mac, both running the latest Lion. I have tried this with both USB Flash drives and with external hard drives. Whenever I drag and drop from Finder to either the flash drive or the hard drive, the copying begins, but always gets stuck with the pinwheel at almost exactly 4.17GB. At first I thought that the formatting of the flash drive might be the culprit, but it also happens on the external hard drive that is formatted for Apple Extended.Â
A very "time and effort" intensive workaround is possible if I just copy fewer than 4 GB at a time, which is what I have been resorting to. But this won't allow me to transfer my Windows 7 Parallel virtual machine, since that one file is over 90GB. As additional information, it appears that Time Machine isn't bothered by this limitation, since I can backup and restore these huge files from a backup. Unfortunately, Migration Assistant doesnt seem to permit the granularity of restoring just one file. why the system hangs at 4.17GB of transfer? By the way, this happened with Snow Lion too. It didn't just start with Lion.

I am currently working on an IMac Quad Core Processor W / OS X Mavericks 10.9.5, with 16GB of RAM and 8GB video Card and a 1TB drive (512 Solid State/512 Hard Drive). I am using Final Cut Pro X version 10.1.3.Â
I am pretty new to a MAC system and still learning the in's and out's of the system and how to use it. I have done 4 projects in FCP X and I have around 28GB of data storage left on my 1TB drive. When I looked up one project that is 54 minutes long, it says that file is 500GB and it is not loaded with special effects at all? I cannot believe that it would take that much space. Â
Here is some information on how I start a project...
I will create a new Library, then I will import media into separate events such as Camera 1 video, Camera 2 video and such.Â

Final Cut Pro X, OS X Mavericks (10.9.5)

I think I have found a bug in Finder where I cannot copy large files from a bus powered USB external. I get this error:
"The Finder cannot complete the operation because some data in "..." could not be read or written (Error code -36)"
I think I have eliminated hardware as an issue:
1. The problem is repeatable (and always happens) on my Intel Macbook Pro, Intel Mac Mini and G4 Mac Mini
2. The problem happens whether I have formatted the external as HFS+ or NTFS (I can't use FAT32 for files over 4GB, e.g. VMWare disk images)
3. I can copy the files off the external with my Windows Vista machine (mostly dormant these days) and an XP laptop (I use for work), using Explorer.
4. The same problem happens with two different external enclosures (An Xtatix Portadrive and a Beyond Micro mobile Disk). I have also tried 3 different 2.5" drives in these enclosures.
5. If I boot my Macbook Pro into Vista using Bootcamp, I CAN successfully copy the files using Explorer.
6. I CAN also copy the files OK if I use Terminal and the 'cp' command (it works for all 3 machines)
7. I have NO problems with large files and Finder if I use a powered external with 3.5" drives via USB or Firewire (HFS+ or NTFS) on any of the Macs.
As you see, I think I've been pretty thorough. It seems as though Finder must be at fault when used with a bus powered USB external.
I should also mention that all 3 of my Macs are on Leopard 10.5.3, though I did also boot a my Intel Mac Mini into Tiger with the same result (Finder failed, 'cp' worked).
I have reported the problem to Apple, but wondered if anyone else has had a similar issue...and hey, a solution would be a great bonus!

I recently deleted my Bootcamp gaming partition so I could make it smaller. I then realized I need more space and so later on I deleted it again and tried to make it bigger. I got the infamous "files cannot be moved" error which is Apple's nice way of saying "sorry we don't build in good defrag tools for large files, just small ones". Suffice to say, I cant install Windows without either doing a bootdisk defrag of my system using a third party tool like iDefrager or doing a fresh fromat of the hard drive.
I think I would like to do a fresh format as its quicker and cleans out your system but my problem is thus: I dont know if I should back up my mp3s, pictures, aim convo logs, etc. to an external and just recopy them over with fresh installs of all my apps or if I should do a Time Machine restore (either the restore in the system disc or a restore after a fresh format and install of OS X). I have a Time Capsule so lag is a factor there. Which is the best option for me to pursue!?

I am moving a few folders which are in excess of 4 gig each from one hard drive to another to try and free up space, of course I am aware that one is formatted for mac and the other is ms dos but I already have stuff on it and can't take it off in order to reformat it (or I do not want to). Is there a program that exist that will allow me to do this, I was only thinking in regard to programs such as Senuti for backing up an iPod. Since an iPod is so huge, you tell the program where to put the songs and regardless of the space it will do it, no questions asked. If you understand what I am on about can you please assist me in any other way in regard to solving me problem.

I recently picked up a USB Hard Disk, I plan on copying large files to it (for example 20gb VMs), I am wondering whether or not finder can copy files as large as 20gb one at a time because the last time I tried to do this on a USB Stick, the file transfer would either freeze or would end up taking way too long to transfer and in the end I had to pull it out and having to reformat it. DOes anyone here know if such things will happen again copying these files?

So, its come that time where I am starting to get the "your startup disk is almost full" messages, and I was wondering what software you guys use to identify the biggest files on your computer to efficiently delete and make more room?
