Marking a file extension during saving???
Hi.
The problem is, when a file is going to be saved, how can I do such a improvisation like a "save as" dialog?
To avoid the "poor" technique of, user typing the extension, can do a something like a "save as" option in the JFileChooser saveDialog(), to offer a list of extensions and when user pick up one, to add it to the file name path, during file saving ?
Thanks!
Here is the solution I came up with. It will add the file extension if a FileExtensionFilter is selected, and you can set it to warn on write over

Rename file extension during a file upload ??
I need to rename the extension of a file at some point during the file upload. I am not sure where to do this at.
The file needs to be renamed before it is written to the directory.
Basically, the file will come in with a .txt or .doc type. Based on a users profile, I will change the type to a non-relavent number such as 1111.
Here is my upload servlet. Can you tell me where to change the type so it will write the file with the new extension?
Thanks.

Saving attachments on Snow leopard mail loses file extension when saving over an existing document
Saving attachments on Snow leopard mail loses the file extension when clicking on an existing file to copy the name. Is there something I can switch on in the preferences to fix this?
I work for a publishing company where our clients send their copy to us in Word documents. We might have several versions sent to us before the final version comes in.
It is instances like this where we want to overwrite a document on the server with the most up-to-date version (which is usually named differently to the original file). We really don't want to clutter the folder with lots of different revisions. The quick way to do this is to click on the document we are replacing (this copies the document name). Previous versions of OSX Mail used to keep the file extension but Snow Leopard seems to remove it.
It's annoying as there is no particular logic to this. We just have to manually type ".doc" at the end of the document.
Incidentally, this happens with any attachment file type. -
JFile Chooser - Add automatic file extension while Saving
Hello,
I have a JFileChooser, which I use for saving output from my program.
Problem is whenever I save a new file I have to manually specify its extension, otherwise I get an undefined file with no extensions.
I want my default extension to be ".txt".
Any ideas on what method to use? Is this a trivial issue or a complicated one?
Thank you,
BerkanWhat about this? Not tested.

File extensions and other formats
I'm having trouble with file extensions when saving AW files in other formats. I suspect it may have to to do with a recent upgrade to 10.5
I have (as recommended in the forum) deleted the AW plist files, but it didn't help.
Here are the symptoms:
1. When saving, "Hide extensions" is always checked. I remember it as always being unchecked (which I prefer) . Unchecking it every time is getting annoying.
2. If I uncheck Hide Extensions, I can save as an AW file with its cwk extension, no problem
3. If I change the File Format to something else, like Text, then the Hide Extension box (which I had previously unchecked) is now checked again. The previous cwk extension disappears, but the period remains.
4. If I then uncheck Hide Extensions, a second period appears.
5. If I try to get rid of the extra periods and add txt so that the file is filename.txt, I get an error message that says I can't use the extension ".txt", and that the required extension is "." Using both leaves me with "filename.txt."
6. The only solution has been to let it save with Hide Extension checked, then go into the finder, use Get Info to unhide the extension, and then save it with the correct extension, which is getting to be a real pain in the patoot.
Help, anyone? I'm ready to downgrade back to 10.4.
RJWelcome to Apple Discussions
Downgrading to 10.4 won't help much. The problem lies in AppleWorks being a Classic application that was carbonized to run in OS X. It just doesn't "understand" extensions. Although adding the period in Leopard is new, the problem with the error messages when you save an AppleWorks document as text or Word & add the appropriate extension is not new. I've given up & just add the correct extension in Finder. -
How do i select the file extension type?
using imovie '11.
i've finalised a project and exported it. it automatically saved as a .m4v (itunes) file.
my question is:
is there any way to manually select the file extension when saving/finalising a project?
for example, i might be required to save a project as a .mov file.
thanks in advance.Publish the movie on itunes then, drag the movie on your desktop. After right click on the movie icon and click get info. Go to name and extension and change the .m4v to .mov . This should work because, it works if you want to change from .mp4 to .3gp etc... This saves you time because you don't have to use a movie converter.
Best of luck Jono -
I want to shut off the automatic append file extension when saving a file in Illustrator CS3 to not have the .ai appear at the end of the file name. How do I do this?
In a manufacturing company where naming conventions are in place, we don't want .ai placed into the file name on certain files. I am running a Mac and never had to have an extension in the filenames before cause Macs always hid the extension? I have the Finder preference to not show extensions but since Illustrator is placing it as part of the filename in the save dialog, it shows no matter what. What does adobe expect us to do, click on the file in the Finder and get infor, then click hide extension? We are making the conversion from Freehand to Illustrator (not by choice) and this is turning into a big nightmare on a lot of issues.
Give me a lecture on the mapping issue. If I remove the .ai in the save dialog box before saving, I haven't seen any issues yet. My applescript studio applications don't save the .ai when they drive Illustrator. No issue there either. Tell me what you know about mapping issues.
Don't want the app to automatically append file extension. Can it be done.... Yes or No? -
Double file extensions keep showing up when saving a file in Illustrator CS3???
I just installed the CS3 suite and when I am saving files in illustrator I keep getting double file extensions. For example if I save a file named "filename" as a .eps file it shows up in the save window with filename.eps.eps Also, if I click through the possible file types to save it keeps adding them one after the other so if I click. say pdf eps and ai the file in the "Save As:" window looks like this " filename.pdf.eps.ai.ai" Any ideas why this is happening? I keep having to mouse click in the "Save As:" box and delete the extra extension. This is really annoying!!
I am running the design premium CS3 on OSX 10.5 on a mac pro.
Thanks.>Wade... I've seen it... and reported it originally to Adobe. I've since realized it's a 10.5.1 issue. It doesn't happen with 10.4.11, just 10.5.1
I've seen extra periods (.) and extra extensions.
then you and Dave have the same conflict with a third party software, corrupt font, corrupt preference or the like because it is not happening o my Mac Pro and I have the same model Mac as you do and I am working fine in 10.5.1 and only problem I have had with AI CS 3 is when I tried to place a 3D CAD file with the extension .dxf which is not really supported.
I have not seen this even once. Would you like to see screen shots, it honestly is not a 10.5.1 or Illustrator issue on its own. This has to be user specific. -
I save a lot of images using firefox, often times from a large batch or series of images. It used to be that I would click on a previously saved image and the entire file name including the file extension (i.e. image_example.jpg) would appear in the "save as" line. Now when I click on a previously saved file, the file name appears without the file extension (i.e. image_example). Which means I have to manually type .jpg every time. For a large collection of images that I am hoping to use the same root file name and then add chronological numbers at the end, this has become incredibly frustrating, especially as it is a previously unnecessary task.
I am using a new Macbook Pro and maybe there's something Apple related to this...? It did not happen on my old PowerBook G4. I have file extensions turned on in System Preferences.
It should be noted that I have searched high and low and have even gone into the Apple Genius Bar where they were just confused as I was and of course ended by urging me to use Safari (shocker!) as it has all kinds of new extensions and bells and whistles. I seriously feel alone on an island with this dumb, hard to google problem. Thanks so much for any help anyone out there might have.
I mean: is this as simple as changing a setting in about:config?
Your assistance is greatly appreciated.Thanks for your response Mylenium, however like I mentioned multiple times, I did change all of my trackpad/scrolling settings in system preferences. And if I wanted to use a normal mouse (or a tablet), I would've gotten an iMac instead of a MacBook Pro. I travel often and work all over the place, not always with access to a decently sized workspace that would be required for using a mouse or tablet.

Sufficient free storage.... tried the reboot and install... Just received an iOS update I'll install tonight and do another reboot...see what happens. Going to have to start saving double..

I have the new Snow Leopard system on my iMac. I saved several images from an art site. The file extension on each image is "htm". when I try to open each image all I get is gibberish tpye text.
Can convert these "images" to jpeg files so I can view and edit them?
thanksIf the images have a .htm(l) file extension then you need to rename the files and give them an image file extension like .jpg<br />
That should be sufficient to make programs recognize them as images. -
Does anyone know how OSX can create a file with the ending ".saved"?
Background:
Somehow my inlaws deleted their Mail.app preference file (mail created a new one and became defaulted, losing their mail accounts) but the old one was still in the Library with an added extension: "com.apple.mail.plist.saved". I can't figure out what they did, nor how to recreate this event. Using Copy or Archive do not create this extension. I deleted the new preference file, removed the .saved extention from the old one, and the Mail was back to normal. All I know is it happened while working on a Pages document that they were intending to email.Thank you so much Andy. That really takes all the mystery out of it and now I know exactly what happened, as all the pieces and the things they said are now making sense.
After Mail crashed and got defaulted it asked for the password for their defunct .Mac mail account (automatically imported from the .Mac prefs). They went to the Keychain to find the password and somehow ended up deleting the password to iChat (and .Mac) as well.
I told them it's time to upgrade to Leopard so I can get TimeMachine up and running. I also may make them write their passwords in a .... BOOK .... and hide the Keychain app!
Thanks BDAqua. The first thing I did was a permission repair and restart. -

Did you format your hard disk on that Mac any differently? -
Support for file extensions with more than three characters when saving - I want my FLAC!
Why does the Wave Editor still drop characters from filenames with more than three character extensions when you save a file? But since -opening- a FLAC file with an extension of ".flac" doesn't get chopped to ".fla", why does Audition still chop off the extra character when -saving-?
It gets old quickly when you have to save, close and reopen files in order to get Audition's Multitrack editor to play nice and be able to find files when you reopen the Session.
Given that the FLAC filter is open source, I may just have to modify the code and recompile it to force a save to ".fla"... But of course, ".fla" is a Flash file extension, which I also use, so that is a crude hack for me.Hi bro...
use in BYTE mode in place of in TEXT mode. and at the end of each line give some special charactor so as to distinguish between lines.This is effected by unicode check too

I received an email containing a spreadsheet created using Mac Office 2004 on my new MacBook Air equipped with Mac Office 2011. When I saved the document, my Finder lists the document without the .xls file extension. Why?
All other .xls documents created by Mac Office 2004 retained the .xls file extention when I migrated them over to the new MacBook Air.I know what happened. When I saved the document I somehow hit the Hide File Extension box. Sorry to trouble this group. I simply resaved it w/o activating the Hide File Extension feature.
