How to split a large file when disk space is limited

I have a long (200 minutes) DV clip which uses up most [40 GB] of my external hard drive. The last 90 minutes of the clip is blank, and I need to delete the corresponding [18 GB] filespace to free-up space on my hard drive for editing.
How do I delete a portion of the file without having the 22 GB of free space Quicktime seems to need to temporarily store the new (smaller file).
Thanks,
David

I modified the program as follow:
ZipEntry entry = new ZipEntry(file.getName());
entry.setTime(file.lastModified());
zip.putNextEntry(entry);
byte[] bytes=new byte[1024];
int len;
while ((len=in.read(bytes))>0) {
zip.write(bytes,0,len);
And now it is working. I can zip a file with 125MB size.
Thank you for your help.

My C drive is 19.5 GB. xp sp3 took 5.05 GB.Firefox also installed here . There's no room for new downloaded files.So I changed the save to option in another drive. Still when downloading large files 'low disk space' message shown.

suppose I want to download a 4 or 5 GB file,in C:/ there is usually 2 or 3 GB left.So I changed the directory of saved files to E:/.Still low space problem occurs and the newly downloaded file is not saved.A low disk space message is shown.Why is this showing?How to resolve this?

in options under the "general" tab change the download folder,if that does not help change the option to "ask every time".I recommended to use DAP to download your files its great and accelerates your speed quite a lot.

Combining several iMovie projects when disk space is limited

I have searched the Forum but cannot find a precise solution to my problem. If it already exists, could someone kindly point me in the right direction?
I have created three separate iMovie 06 projects which need to be combined into one continuous movie of about 40 min. duration. Each of the three projects is 11 - 12 GB in size, and I have only 6.5 GB space remaining on my hard drive.
Is there any way to combine the three projects? Or perhaps some way to import them all into iDVD to make a single DVD?
Thanks in advance!

Computer Rule No. 23: There's No Substitute for Disk Space
Computer Rule No. 24: You Never Have Enough Disk Space
Plan A) copy files to an external, MacOsExtended formatted harddrive.. erase originals; 6GB is dangerous little disk space, iDVD will freeze your whole system while working immediately ..
Plan A2) .. in case you have access to a 2nd Mac, you can launch that device in 'Target Mode' and connect it via firewire ... for 'abusing' it as an 'external drive'..
Plan B) playout finished projects to camera, erase projects, import from tape straight into iDVD.. but probably, again, not enough disk space for those 'hidden' temp files, iDVD has in use (=10-15GB free is min. rec. AFTER importing files/tapes .. )
Plan C) .. no, I don't think there's a 3rd plan .. aside purchasing disk space..

File Splitting for Large File processing in XI using EOIO QoS.

Hi
I am currently working on a scenario to split a large file (700MB) using sender file adapter "Recordset Structure" property (eg; Row, 5000). As the files are split and mapped, they are, appended to a destination file. In an example scenario a file of 700MB comes in (say with 20000 records) the destination file should have 20000 records.
To ensure no records are missed during the process through XI, EOIO, QoS is used. A trigger record is appended to the incoming file (trigger record structure is the same as the main payload recordset) using UNIX shellscript before it is read by the Sender file adapter.
XPATH conditions are evaluated in the receiver determination to eighther append the record to the main destination file or create a trigger file with only the trigger record in it.
Problem that we are faced is that the "Recordset Structure" (eg; Row, 5000) splits in the chunks of 5000 and when the remaining records of the main payload are less than 5000 (say 1300) those remaining 1300 lines get grouped up with the trigger record and written to the trigger file instead of the actual destination file.
For the sake of this forum I have a listed a sample scenario xml file representing the inbound file with the last record wih duns = "9999" as the trigger record that will be used to mark the end of the file after splitting and appending.

In the sender file adapter I have for test purpose changed the "Recordset structure" set as "Row,5" for this sample xml inbound file above.
I have two XPATH expressions in the receiver determination to take the last record set with the Duns = "9999" and send it to the receiver (coominication channel) to create the trigger file.
In my test case the first 5 records get appended to the correct destination file. But the last two records (6th and 7th record get sent to the receiver channel that is only supposed to take the trigger record (last record with Duns = "9999").
Destination file: (This is were all the records with "Duns NE "9999") are supposed to get appended)

I ve tested the XPATH condition in XML Spy and that works fine. My doubts are on the property "Recordset structure" set as "Row,5".
Any suggestions on this will be very helpful.

Hi Debnilay,
We do have 64 bit architecture and still we have the file processing problem. Currently we are splitting the file into smaller chuncks and processsing. But we want to process as a whole file.
Thanks

How to send a large file in XI ?

How to send a large file in XI ?

hi,
use a splitting mechanism to convert large files into smaller files and process them as if they where independent.
You can use the "Recordsets Per Message" parameter in the File Adapter sender comm channel by using File Content Conversion, to create a new message for each 1000,10000,etc records in the source file...this could be a way of splitting.
If you scenario works ok for small files, maybe you can develop another scenario that runs previous the current one, that only splits files (e.g. File-XI-File) and then puts the output smaller files in the directory that your current scenario monitors.

I'm a new Apple user - when I deleted some large files the available space didn't increase - I emptied the trash - am i missing a step to tidy the hard drive?

I'm a new Apple user - when I deleted some large files the available space on the hard drive in the activity monitor
didn't increase - I emptied the trash - am i missing a step to tidy the hard drive?

Open the Finder.
From the Finder menu bar top of your screen click View > Show Status Bar
You should now see the the free space available at the bottom of any Finder window and that should change after you empty the Trash.

How do I move large files from a Windows computer to my MacBook Pro? There are a lot of photos (tiffs

How do I move large files from a Windows computer to my MacBook Pro? There are a lot of photos (tiffs, jpgs, some photoshopped files), iTunes library, word docs. Is there a particular type of external hard drive that can be used or am I limited to copying stuff onto z-drive and moving that way?

If both computers are on the same network, you can share the files from the Windows host using SMB and mount the share on the Mac. Otherwise, the Mac should be able to read (not necessarily write) any storage device formatted in Windows.

Don't use the Secure Empty Trash option on items which don't contain sensitive data. If the Trash is always doing it, create two folders with the same name in different locations, drag the files into one, and move the other into the folder which contains the first.

Why does a mail-merge in MS Publisher split into multiple files when printed as a pdf file?

Why does a mail-merge in MS Publisher split into multiple files when printed as a pdf file?

'Cuz that's what mail merges do. They create multiple documents based on the parent doc and all the names/addresses in your data tables.
Perhaps if you describe exactly what you're trying to do & why you need PDF, we can point you to relevant tutorials.

How to edit the nbu file when the mobile device is...

How to edit the nbu file when the mobile device is not connected?
That software that is available in the nokia site “nokia phone browser” is not useful! Why?
It is not working unless the mobile device is connected (attached)
It is quite slow when editing the contacts! (attached)
Then why the nokia doesn’t offer a simple software that enable us to edit and explore the content of our nbu files?
Is there some workaround in this regard?
Is there some software the can edit the nbu files?
Thank you for the help,
