Compressing Powerpoint files
I am trying to compress a Powerpoint file to send by e-mail. It is currently 39.7mb, but when creating an archive, to zip the file, it only reduces in size to 39.0mb. Other files reduced by a little, but not by as much as I expected. Is there something I am missing when trying to compress the files?
Thanks
You're not "missing" anything. Some forms of compression are better than others, but most importantly the content of the file will have a big impact on how effective compression is (e.g. if there are embedded video media, those will not compress much).
One possibility is to save the file as a PDF (if you just want the recipient to view the slides, not edit the file).
You could consider alternatives such as FileChute, or splitting the file before sending it (e.g. with something like Split&Concat.
Hope this helps...

HOW DO I COMPRESS 2008 POWERPOINT FILES SO I CAN EMAIL THEM?
Hi. I am new to Power Point. I spent all day making a presentation, but I was using scanned images and digital images, which I know now are very large. No one warned me to compress the files before I inserted them, so I didn't. Now, the file is too large to send via email. I have been looking for information online about how to compress the files and cant find any answers.
The 2007 version seemed to have a "compress pictures" button on the tools menu. On the 2008 version, there is no tools menu and no compress pictures button. (There is one actually in the save as menu but it doesn't compress the file at all!)
I am at a complete loss and very frustrated. I am terrible with computers. Can anyone please give me advice on what to do to solve this problem? I need it for an interview Thur!
Thank you.I had the same problem, followed the link to the horrible M****soft forum, read the following:
<<Embedded pictures are the common cause for large PowerPoint files. Office for Mac 2008’s PowerPoint has a built-in tool that can compress your embedded images and shrink your PowerPoint file:
1. With PowerPoint open, click PowerPoint on the menu bar at the top of the screen and choose Preferences...
2. Choose the Save tab
3. At the bottom of the window, check the box for "Compress graphics files". This will automatically compress all graphics in your PPT files.>>
..followed the instructions and nothing happened. Tried to leave a scathing reply about nothing happening, was asked to sign up to MSN, stopped that process when I saw that I was giving the right to send me promotional emails... yuk!
soo, did you find a solution to your compressing question?
thanks

I need to email a powerpoint file that is 288MB I need to compress it to 30MB. How do I do this?
How do I reduce a 288MB powerpoint file to 30MB so as I can e-mail it? I am working with maverick.
It’s basically impossible to compress files to that extent. Use a service such as YouSendIt, Skype, or Messages instead of email to send it.

Somehow 1500 web pages were downloaded into my iphone app! That's when the trouble began Now, I keep gettig error message"not enough room on your start up disc. "So I deleted most of theml, but when I compress/delete files, it doesn't help. Now i'm unable to back up to a disc, because I get a similar message about lack of room.. I can't download apple updates or printer updates. My computer is almost unusable. When I took it to the Apple store they had no idea what was wrong.
I bought an external hard drive-Free Agent Go Flex which doesn't seen to function, and has no user interface and apparently little tech support. My cursor is all over the place. No one at Apple seems to be able to fix this computer. Any suggestions for my next move?

Can't open powerpoint files in keynote since Mountain Lion upgrade
Not having much luck and not sure which forum to post in as this could be a Mountain Lion issue, an iWork issue, but is also an iWork and/or IOS6 issue!
Until last week I had Lion on iMac and IOS5 on iPad. I was able to log on to my work network server (school network, I am a teacher) and open powerpoint, word or excel files in keynote, pages or numbers on my iPad. I then upgraded to IOS6 and now none of the files will open up on my iPad. I get the open in screen when I choose a file to open, then nothing happens.
In the meantime, I upgraded my iMac from Lion to Mountain Lion. Since I was having problems accessing my work files and viewing them on my iPad, I decided to buy Keynote on my iMac in the hope that I could get on with some work on iMac rather than iPad. I logged on to my school server and tried to open a powerpoint file and for some reason it downloads it as a pptx.exe and if I try to open it I get an error message saying "You can't open the application xxx.pptx.exe because Microsoft Windows applications are not supported on OSX". It shouldn't be a .exe file it should just be a powerpoint file! When I open Keynote and look for available files on my iMac, the file I just downloaded is greyed out.
Hmmmmm so I have an iMac, an iPad, two versions of the Keynote app (plus numbers and pages on the ipad) and can't open any of my files from my school network. That seems a lot of money in one pot Apple and something has changed from Lion to Mountain Lion, and from IOS5 to IOS6 which is preventing me from doing my work. IOS5 allowed me to open any ppt, xls, doc, pptx, xlsx, docx file from my school network so why since upgrading to IOS6 can I suddenly not open them??
Now having forked out for Keynote on my iMac, I have the same problem.
I am able to open attachments in emails and I am able to log on to the school VLE and access and open files. So it is just something to do with opening from the normal file system that I can't do.
I posted in the iPad and iWork forum and had no replies. However, Apple iWork team have contacted me after reading my post re the iPad issue of opening files from my network. I've provided info to them and am waiting for a response, but in the meantime I have now discovered there is also an issue on my iMac. Hopefully they will read this too or someone else will perhaps know what is going on.
It is a worry that I can't do any work using my Apple products seeing as I have bought them! I have had to go back to bringing my windows laptop home everyday which I hope is a short term solution. I have loved the fact that I could access everything on my school network from my iPad in the past and not have to drag a laptop around. I am also worried that this means pupils can't access the files too if they are using Macs, iphones, ipads etc and have upgraded to Mountain Lion or IOS6.
Hoping someone can help
Thanks in advanceThanks for the response but I think you've misunderstood the problem. I can not open any type of PowerPoint file off my server in keynote. This includes .ppt and .pptx files. (Also includes .doc, .docx, .xls, .xlsx in pages and numbers).
Even if what you said worked it would take forever to go through every file and save them all as ppt 2007. Plus of course, I don't know what files I will need when. There are hundreds of resources I need to access when I'm at home. I need the flexibility to view the files when i need to and on the go. Normally I can download them off my school network on to my iPad in keynote and edit them then I email them back to myself ready to use the next day or to save back to my network. Currently I can not download any Microsoft office file. So I am now forced to have to lug my laptop home everyday, rendering my iPad and iMac useless. I can't pre-empt what I'll need and save it as .ppt as that is completely inflexible and that won't open anyways as this is not an issue with the version of PowerPoint file. This is an issue with how all Microsoft files are downloading from my school network to my iPad and iMac. I want Apple to allow this to work like it used to before the upgrades in operating systems. I wish I hadn't upgraded as it worked perfectly. :( -
How do I port my Windows Word, Excel, and Powerpoint files to the MAC? What software is needed on the MAC to use them? Thanks.
You can certainly use iWork, though I hesitate to recommend it to a seasoned Windows user simply because it would add another level of the unfamiliar with which you would have to gain familiarity. The iWork applications are certainly very competent and in most respects both easy to use and surprisingly powerful. They are not 100% compatible however, though that typically manifests itself in document formatting issues rather than anything more significant.
I have never attempted to import emails from a Windows system into MacOS - other than in Outlook connected to an Exchange server, thus not really an issue at all. I doubt that the Mail app in MacOS can import directly, but of course you could always set the account(s) up on the Mac and then forward emails you want to keep from the PC. Not elegant, but it works. Virtually any Windows document or file, whichever application created it, can be opened or converted for use on a Mac, and using both systems on my desk each day I rarely see any issues switching stuff from one machine to the other. You may stumble over one or two issues, but likely not significant.
In switching platforms there will be some inevitable issues, not so much with being able to import your stuff because there's usually a workaround or a utility that can help, but just with getting familiar with the platform and the differences between Windows and MacOS that can obscure their similarities. From time to time the support community here hears from a user who has found the migration very problematic and regrets it, but for the most part the phrase 'I should have done this years ago...' is rather more prevalent! -
Converting a Keynote document to Powerpoint file doesn't work
I tried to convert Keynote documents to PowerPoint files that can be viewed and edited by PowerPoint users on Windows or Mac OS computers. All I got was a error. Can any one tell me how to make this work.I did every thing that was in the instructions.
To create a PowerPoint slideshow:
Choose File > Export and then click PowerPoint.
Click Next.
Type a name and choose a location for the file, and then click Export.Hy Kyn, thank you for answering.
Every slide on my presentation has animated objekts. And every slide is linked (by hyperlink) to every slide on the presentation. So I want to give the user the chance to interrupt and to go to next slide. Therefore is an arrow to klick on, which has a hyperlink to next side (or do go to start, or to go back) - during the slide-animation is working.
That works fine in keynote, but it doesn't work after the export in QT. In QT it is not possible to interrupt the sequence of the animation. When the sequence is (performed) finalized, the klick on the arrow works, and I can go to next slide.
But interruption is not pssible.
Tanks in advance for your answer!

Trying to zip / compress a file in Windows Server 2008 & SQL Server 2008 R2 server
Hi,
We are trying to zip / compress a xml file that has been created by retrieving data from SQL Server 2008 R2 database running on Windows Server 2008.
To compress this file, we cannot use any external softwares like 7-zip or WinZip.
So, we would like to know if there is any windows default compression tool that works on command line to compress the file?
As this is a live server we cannot apply any other softwares.
Please suggest any ways to do it in Windows Server 2008 machine.
Thanks & Regards

My IPod no longer shuffles songs within playlists that are clearly set to shuffle. It is about 3/4 full so I thought of maybe compressing the files to get more space. Do you think that is the problem and if that might help?
Storage space on the iPod would not affect shuffled playlists or playlist shuffling, though substantially full iPods may wind up skipping songs on larger playlists after a while, and require a restart. As for compressing the files themselves, you can automatically re-encode files to a lower bitrate by checking the box on the summary page when your iPod is connected to your PC/Mac.
As for the shuffle problem, after restarting your iPod (hold the center button and Menu for a few seconds, until the Apple logo appears), make sure you're telling the iPod to shuffle the songs in a playlist by repeatedly clicking the center button until the Suffle Menu comes up, then scroll to the right to turn it on. From that song forward, the playlists' contents should be shuffled every time the playlist ends, or is accessed from a new song.
Shuffle does sometimes turn itself off, I've found, so double-check the setting is still on. Also, iPods shuffle by randomly assigning a playlist order for your songs, which is different from traditional shuffle (on, say, iTunes or Windows Media Player, where the new song is determined at random upon the current track ending. The iPod only chooses a random order of songs when you shuffle, to conserve battery life and queue up songs coming up on the playlist in the event of a shock). -
I'm trying to invoke EXCEL or POWERPOINT file into the browser IE 6.0. The
I'm running TOMCAT locally on my PC (running Windows NT).
I'm trying to invoke EXCEL or POWERPOINT file into the browser IE 6.0.
The output is coming out all scrambled (almost like ASCII code or something),
where it seems like the applications are not firing up.
However, an MSWord file shows up fine. So I go to the WEB.XML file in the TOMCAT\CONF
folder and notice that a MIME type has been set up for MSWord and not the other two.
I set one up for EXCEL and POWERPOINT but the XLS or PPT files still don't work.
So, just for kicks, I comment out the MSWord MIME definition but the MSWord file still worked!!!
I can't figure out what's going on here.
I'm stopping and starting the TOMCAT service each time I make changes to the WEB.XML file,
but it seems like none of the changes are taking affect.
I install all the viewers for MS-Word, ppt, and excell.

Today i was transfering a few folders with pictures and videos over to another mac and I noticed that before i sent the file iChat would compress it. Now this is understandable because they were fairly large files, over 2GB, and this would make them transfer faster. The problem is that I was transfering the files because my mac is low on hard drive space and I was trying to free some up. By compressing the files first it was using up more space on my hard drive and I quickly cancelled the compression. I soon realized though that my hard drive space was still disappearing into thin air. I only had 6GB left and was running out fast. As it reached 2GB I began to quickly delete large files I no longer needed hoping that I wouldn't run out of space. It dropped all the way down to 12.4MB before it finally stopped, even with me deleting files. I'm not quite sure what was happening to all of my hard drive space, but was wondering if maybe iChat continued to compress the files even after I cancelled the compression. Anyways if anyone knows why this happened or where iChat stores the files it compresses that would be greatly appreciated.
Hi,
I have heard of this before.
One report suggested it was only PDF files their case.
I cannot replicate it with any pic files (Over 2Gb) PDF or otherwise or files and folders combos.
My tests were from Lion/iChat 6.0.3 to Snow Leopard (iChat 5.0.3)
I would have thought iChat would have created the Zippped/Stuffed files in the same folder as the original items
(i.e pic in the pictures folder (or relevant subfolder) and other files and documents in the Documents folder.
With any application that does Stuffing/Zipping it will create temporary space for doing so.
Much like the way a graphics app creates a Scratch file to keep the 20 or so Undos it works with. (with graphic Apps you can make the Scratch file on another Drive if you have one which can help)
Do this:-
with iChat Open go to the Window Menu.
Select the File transfers item
In this Window (that pops up) select the File that was going to be Transferred.
When it is highlighted then do a Right-Click or Control Click and select the option to Show in Finder
Does it list the zipped file ?

KB2878233 corrupts PowerPoint file type associations (bis).
Dear,
I posted the question below a week ago in the Office forums on answers.microsoft.com, but did not receive any reaction. Allow me to repeat:
Installing the KB2878233 security update corrupts the file type associations for PowerPoint files in the following environment: Windows XP SP3 ("fully" updated) / PowerPoint
Viewer v. 14.0.7015.1000.
PPT files get associated with MOC.EXE for opening them. Uninstalling the update does not restore the original associations. The problem can be alleviated by repairing the PPT Viewer installation manually.
Question: can this High Priority security update please be re-released through Windows Update without the corruption effects?
TIA.
Kind Regards,
Jan J.
Brussels, BelgiumHi,
We can try to change the file associate in Registry key:
For all users on this computer, please change associate program of the .doc or file type you would like to under
HKEY_LOCAL_MACHINE\Software\Classes.
For current user account, please change associate program of the .doc or file type you would like to under HKEY_CURRENT_USER\Software\Classes. If there is no such extension, please create new keys for it.
Hope these could be helpful.

How to view Powerpoint files without Office
Hi,
I just need to view a .ppt file on my Macbook (os x 10.5.2), and I tried to use the Powerpoint Viewer 98 for Mac from microsoft, but it is a classic application that is not supported on leopard. I also tried openoffice.org, but it converts the file poorly and leaves a lot of things out. Is there any other way to simply view a powerpoint on a mac without buying office or iwork?
ThanksLooks like you have done your research and know what to look for. You are right, I couldn't find anything that would run under Leopard and view Powerpoint files unaltered.
If possible then have the sender of the file convert to it to a .pdf (Powerpoint 2007 can do this under windows).
