Sending attachments the file extension is dropped, using Mac?

When I send attachments (various file types) the people receiving the file does not have an extension. Is there a setting on my Mac or Thunderbird that is hiding the extension??

It's more likely that your recipients have their systems set to "hide extensions for known file types", which is the default Windows setting. Although, it's also possible, for some file types, that TB fails to properly encode the attachment.
What happens when you send attachments to yourself, or receive attachments from others?

What is the file extension for photoshop for the blanks following the period in "photoshop,___"? I have an older desktop which includes older photoshop files which I have asked a technician to extract for me. He asks for the extension. I can't

I ned the extension for the photoshop program, that is, the letters following the period as shown by the blanks in this: "photoshop.____" I cannot find the extension in my laptop. The photoshop program is a couple of years old and my files are in a desktop out of use for a couple years. I brought the desktop to a technician, asking him to extract the photos. He asks me for the file extension.

If you using Windows you can use the control panel Folder options or from Windows File explorer menu tools>Folder options view tab to change what Microsoft hide on you. Have windows display extension. Apple hide information from users also.

On ESR 17, the DOCX attachments in my e-mail (I use Optonline) ignores the file extension. (my e-mail works fine with IE). This was fine with Firefox 10.0

I have been using Firefox for a long time. I installed ESR 17 recently. Since then I can't open DOCX files in my e-mail (optonline.net). It comes up as "eFax Messanger files". It obviously does not reconginze the file extension because whe i try to open it using Word it reads it as if it was a text file. If I use IE I have no problem opening the same attachment in my e-mail. I know atleast two other people who have the same problem.

Batch Rename with additional "."s, drops the file extension. Request for "Keep File Extension" option...

I NEVER name files with extra "." s in the name. I realize that all OS's (even Windows) will recognize it, but I haven't gotten out the old mindset of 8.3 filenaming... Although I do use longer names. So... I was surprised to see that when I was renaming files as per a clients naming preference to add a period within the name, the file extension is removed.
For example:
original file - 2014_10_31_1643.CR2 when batch renaming to "2014.31" + sequence, drops the "CR2" extension.
but.... if I change it to "2014_31" + sequence, the ".CR2" remains
Since adding multiple "." is a legitimate naming convention, shouldn't the file extension remain? Or, possibly this could be made more flexible by adding a check box "Keep file extension"
just a thought.

The finder will only select the filename only for "known" file types.

Why do the file extensions (.jpg .gif .png) no longer appear when I click on a previously saved image to use that image's file name (particularly important when saving a series of images using the same root name)?

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.

Pse 7 changes the file extensions, by using a -1 up to 6 times on a photo, how to stop this problem.

I cannot keep up with my photos, they somehow change the file extension by adding
a -1 over and over, how can I stop this process
to keep a single file extension?

I checked out the backup/sync, it is not turned on after checking. Also I do not have a second computer as a backup, I use an Esata drive of 1 TB.
I have a photo called Rose.jpg, later I try to open the file and it tell be its lost. I try to reconnect, no luck, then I manually try to find the file and its called Rose-1.jpg or up to Rose-1-1-1-1-1-1.jpg or Rose-1-1-1-1-1-1_edited.jpg. I do not understand what is taking place in my computer with my photos. I have about 17,000 photos and I am having a real problem.
Any help would be appreciated. sghmotorhome

Can the file extension be removed when using the File Special Field?

I placed a Special Field on the top of my topics that gives
me the filename for that specific topic. I used the Insert >
Field > Special Field > File and the File Name is inserted
where I want it. The problem is that i don't want the file
extension to show, just the name. I can't figure out how to do
this...Any suggestions....anyone? Maybe a Script or an applet? Any
input will be greatly appreciated...

Thank you for your response. I did try something similar to
what you suggested but the problem is that whatever I modify it
automatically puts it back like it was as soon as I try to save it.
This is probably because I used the Insert Special Field commands
from the Menu. It automatically places this on the code:
017.htm
Where 017.htm is the actual name of the file for the specific
topic. This means that it's apparently doing this on the background
somewhere I can't see and inserting the value on the code for the
topic...
I hope that made sense! Again, I thank you in advance for any
suggestions...

"Could not save x.jpg because the file is already in use or was left open...

Win 7 pro 64, CS5.0 using InDesign 7.0.4 and Photoshop 12.0.4 x64.
Using InDesign to create a manuscript with images. Right click on image to "Edit Original"
Opens image in Photoshop. Make changes, go to save.
Error message "Could not save x.jpg because the file is already in use or was left open by another application"
Using a free utility called Unlocker Assistant, it shows that the file has been locked by InDesign
The workaround is to then use Unlocker Assistant to unlock the image in in the Links folder, but this is a pain and it is happening too frequently.
Putting in that error message I get no google matches.
Anyone know why Indesign is locking the image, when it is the InDesign program that is supposed to be sending it to Photoshop for editing so it can be changed and then overwrite the original image?
Note that it is not consistent but I cannot find any pattern to determine why it sometimes fails and other times allows the altered image to be saved.

Cannot save as PDF - "Could not save a copy as (filename) because the file is already in use..."

I have a number of PSD files I've created and I'm trying to save them as PDFs.
I can Save for Web and Devices, I can save as a .gif, .eps., and every other format I've tested, but I cannot save as a PDF. I get the error:
"Could not save a copy as (filename) because the file is already in use or was left open by another application."
I'm running Adobe Master Collection CS5 with Photoshop CS 5.5 (12.0.4 x64) on a Windows 7 64-bit machine.
I have a 928 GB HD with 697 GB free.
I have rebooted and tried saving the files immediately after I reboot. I have killed my virus scanner. I have killed a number of other possible culprits including Acrotray.exe and CS5ServiceManager.ext
I have run Process Explorer as recommended by Microsoft and found no applications using the file. I've also tried saving the file to my external hard drive and/or renaming the file with only rare luck.
Nothing seems to fix it.
The boards seem to suggest Adobe isn't taking responsibility for this and pointing it back to the OS or other software. I'm willing to believe them if someone can show me how/where to kill whatever process it is - but at this point, all my indicators point back to Photoshop.

Here is a clip from a past post where user could not drag and drop files to hard drive.
To my great relief I have now sorted this issue and offer the following as the Correct Answer. My sincere and grateful thanks go to Curt and Yammer, above, who have helped me so much in sorting this Windows 7 issue which is clearly very relevant to Bridge users also. Any slowness to grasp what they have been saying is down to me!
The key to solving this issue lies is understanding that in terms of Windows 7 Security, every internal or external hard drive, plus folders, sub-folders and files thereon has an OWNER. Also each OWNER has a certain level of PERMISSION to do things such as moving files to a different folder, deleting or re-naming them etc. If you try to do things that you don't currently have Permission to do, that is when you get an ‘Access Denied’ error message. Also your system has an Admistrator or Administrators and at the outset you need to ensure through the Control Panel that you are listed as one of them. .
If, like me, you didn't realise these things, (and why would you if Microsoft or your computer or hard drive suppliers couldn't be bothered to really make sure you knew about them), then trying to fathom the ‘Access Denied’ problem becomes a stressful and frustrating nightmare as I can testify having spent a week at it!
The steps that I took to resolve the issue and which I believe now constitute the 'Correct Answer' are as follows:
First make sure that you have Administrator rights on your system via the Control Panel
Next ‘right click’ on the Drive whose files you want to gain full access to, for example the drive that your pictures are stored on, and click on 'Properties'.
Under the Security tab you will see a list of Groups and Users on this drive and the Permissions that they have to do things.
Before doing anything to edit these Permissions, first click on the Advanced button. This opens another window with a tab showing the Owner of this drive.
Click on the Owner tab and if you are not already listed as the owner, make yourself the owner by selecting your name from the list. I believe it should appear there if you are an admistrator or user. (In my case at this stage the owner was initially shown as an obscure string of numbers and letters which I believe identified the drive when it was connected to the lap top I was using before I upgraded my machine)
Now be sure to check the box that says "Replace Owner on Subcontainers and Objects" and the click Apply. On completion of this step, the drive in question and all the folders, subfolders and files thereon should now be 'owned' by you. You could check this out by right clicking on a particular folder then clicking Properties > Security > Advanced > Owner. Your name should appear. So far so simples!
Now go back to the Security Tab for your drive (Step 2 / 3 above) and look at the Permissions you currently have. Your aim now is to allow yourself 'Full Control.' If you don’t currently have this level of permission click Edit, select your name on the list, check ‘Full Control’ and 'Apply' the change.
I think I'm right in saying that at this point whilst still working in the Drive directory you are now given the option of ticking boxes which allow you to, in effect, cascade the permission you have just granted yourself to all the files and folders on that drive. Tick the box to allow this and Windows should then take care of the rest.If I'm not quite correct here then in my particular case, for example, all my images were stored on my external drive. The top level, or 'parent' folder in which all my pictures could be found was the 'My Pictures' folder and I had created a number of folders and subfolders ('child ' folders) within that folder. The permissions I gave to the Parent folder – My Pictures – were cascaded down through the Child folders.
On completion of the above step I tested the result in Windows Explorer by dragging a few files back and forth between folders and it now worked perfectly - I was now able to move / delete / rename etc all files without now getting the dreaded access denied message. What a sense of relief! This meant that I could now open Bridge normally rather than having to right click it and 'Run As Admistrator' - albeit that is a very useful thing to do until you get the problem sorted as described.

Could not save because the file is already in use....

For the last couple of days I have gotten this error message several times. It seems it only happens when I do a 'Photo Merge' initiated in Bridge.
I have Adobe CS4 Extended on Vista.
In my 18 years of working with PS I have never gotten this before. I have tried everything, closing all applications, except PS, changing the file name, changing the file extension, nothing works.
I have also researched this topic in the forums. They pertain mostly to Apple computers, and I have not seen a satisfactory solution, explanation, or 'workaround.'
I sure hope hope somebody can help me with this.
Many thanks!

Hi
I have run into this a couple of times, though not in a while.
I believe I got around it by selecting Save AS and saving the file with a new name i.e. Panorama B.tif or something to that effect.
That seemed to convince it that I wasn't trying to save something that was in use someplace else.
Mike

How do I make the file extension (ie: .tif, .jpg, .eps) in OS 9.2 visible?

I'm trying to transfer files from an old G3 (OS 9.2) to a new G5 (OS 10.5.8). Most files do not show the extension in their name. For example, an Illustrator eps has the file name "layout_final". When I transfer it to the new machine, it recognizes it as an .EXE file and cannot open. If I type in the .eps file extension, where is now reads "layout_final.eps", it then opens in Illustrator. I don't want to have to resort to manually adding in the file extension to every file. Is there a way in OS 9.2 to automatically show/turn on the extension in the file name?
Thanks for the help!
Steve

How are you transferring the files ?
It sounds like you're going through some sort of Windows / DOS formatted media.
If you can network the two Macs together instead, do so.
If you can burn a CD or two on the Mac G3, do so.
If you have to use a USB stick, format it to Mac HFS Extended (aka HFS+) on either and use that.
The key is that if you transfer the files using something formatted for Mac, the file metadata should not be lost, and the files will appear on the G5 as expected, assuming that you have suitable apps to open the files in OSX 10.5

Changing the file extension by entering a "?" in JFileChooser

Hi,
I've encountered a weird thing in JFileChooser. If you open the chooser, type at least one "?" in the field for the filename and then hit the approve button, the file extension will change to the text you entered as the filename.
To reproduce this problem, simply launch the JWSFileChooserDemo hit the "Open a File..."-button and as the filename enter something like "?deadbeef". Now click the open button and you will see that the file extension changes to "?deadbeef".
This is a really strange behaviour in my opinion.
I'm using Windows 7 with java 6u16, but the issue is the same on windows xp sp3. Perhaps on linux too. I'll give it a try as soon as I can.
Has anyone else encountered that problem?
Best regards
Edited by: Wurstsalat on Mar 23, 2010 10:30 AM

To reproduce this problemThis is not a problem but rather a feature. I did not know of this till now. Thanks for informing.
As Kevin pointed out this is related to filtering of files.
?deadbeefThis will match all the files which start with any letter followed by "deadbeef". So, ? is a wildcard meaning any one character. Other wildcard can be *, which means any number of characters. Try this:
*.txt
a*.txt
*.jp*g
??.txt I don't know other wildcards...
Thanks!

Changing the file extension in Oracle Spool

How can I get a filename without the file extension?

I using a JFileChooser to select and read a file. Now I want to get the filename without the file extension
JFileChooser j = new JFileChooser;
String file = j.getSelectedFile.getName();
At the moment I get this result "file.dat". I need only the filename.....
Thank you
Thomas

It's quite that.
Here is the code to do that (and the method to get only the extension):
     public String getFileName(String text) {
          int ind = text.lastIndexOf(".");
          if(0<ind && ind<(text.length()-1)) {
               return text.substring(0, ind);
          return(null);
     public String getFileExtension(String text) {
          int ind = text.lastIndexOf(".");
          if(0<ind && ind<(text.length()-1)) {
               return text.substring(ind+1).toLowerCase();
          return(null);
     }(I used 0<ind instead of ind>0 because with the code formatting there is a bug with > )
I hope this helps,
Denis
