Finder - File extensions - strange behavior

Hi,
I have a MacBook and an Intel iMac, both running 10.5.2. I noticed that for some file types, Finder hides the file extension on the iMac, but not on the MacBook. Some examples are VMware Fusion virtual machines (vmwarevm) and Safari web links (webloc). BOTH machines have "Show all file extensions" unchecked in Finder advanced preferences.
The only thing I can think of that could be related is that Leopard has been upgraded from Tiger on the MacBook, while the iMac got a fresh install.

There is a provision to show or hide extensions on a file-by-file basis in Finder's "Get Info" window for each file. Look just below the name in the "Name & Extension" section of the Get Info window & you should see the checkbox next to "Hide Extension." (It will be grayed out if the file has no extension, otherwise it should be active.)
The global "Show all file extensions" preference overrides the individual file's setting & forces all extensions to be shown when it is checked, but it does not override files' settings when it is not checked. (Unchecked is not the equivalent of 'Show none' but of 'do nothing.')
Thus, to hide all extensions, you must use the "Get Info" window to explicitly set the "Hide Extension" option.

Lightroom can't find file - very strange behavior

I really do like working with Lightroom (2.4), even though it has several annoying characteristics (including its speed relative to Lightroom 1). But I haven't encountered anything that is as strange as this:
I sometimes will open a collection intending to select an image in order to print it, or edit it, and the intended image bears a banner announcing that "The file named "[name of image/file]" is offline or missing." I right click on the image and select "Show in Finder" and I get an alert box that says, "The photo '[name of file]' could not be used because the original file could not be found. Would you like to locate it?" Below that it says, "Previous location: ..."
("Previous location:" is followed by the original path to the file.)
Up to this point, what I have described is no different than a missing file problem described here by other users. I hope the rest of this isn't too confusing; please bear with me.
If I click the "Locate" button in that alert box, I am taken to a folder somewhere in the middle of the hierarchy described in "Previous location." If I do a search for the named file (via my iMac's file search function), I find that the actual file is in the folder shown at the end of the folder hierarchy, exactly where Lightroom says it last found it. But Lightroom won't take me all the way there.
On closer inspection, I see that the folder (as shown in "Previous location" not the actual folder) that FOLLOWS the folder to which "Locate" takes me (this is an actual example from today) is called "desktop 12:09" -- but no such name could have been used, colons not being permitted in file names. I follow the path shown in the alert box as I navigate through the actual folders. When I get to the folder one level up from "desktop 12:09" (that is, the folder to which "Locate" will take me - and yes, I could have started there, but chose to follow the entire path for purely academic reasons), I see that there is a folder called "desktop 12/9". Inside that folder is the next folder shown in the hierarchy previously referred to.
Further down in the hierarchy there are two more folders with colons rather than slashes in their names, but of course the actual folders are named with slashes. Lightroom appears to have substituted the colons for the slashes, for some reason (or lack of reason) and now can't find the file.
I did navigate down (through Lightroom) to find the original, but had to copy the path into a text editor so I could follow it. Alas, this particular file was located many layers down. Other images that have been lost track of by Lightroom (also colons in the folder names) luckily were closer to the surface.
I do regular computer maintenance, Lightroom backups, catalog integrity checks, etc. Does this make any sense at all to anyone? I can't figure where Lightroom would have gotten those colons.
I'd love to figure this out, not just for my own curiosity, but because the process of locating the files via Lightroom is quite time consuming.
Thanks.
Leonard
p.s.: I am using an iMac (1.9 GHz G5 processor), OS X (10.4.11), 2.5 G RAM
[Screen name, lkajsdt, created by randomly pressing keys. The registration system would not accept any sensible pseudonym I tried.]

Thanks, John,
I had a suspicion that the slashes might somehow be implicated, but all of the other folders in the hierarchy (as shown in Lightroom's alert box) that have dates in their names have slashes which were not somehow converted to colons (I do not use colons, nor will the Mac allow me to use them; this was all LR's doing). When actually navigating down to the file via Lightroom, not the Finder, the offending folder(s) appear with slashes, not colons -- exactly as they appear in the Finder. Where Lightroom gets the colons, I don't know, especially since they do not appear when I am navigating through the path VIA Lightroom.
I'll work with it again later. I just caught your message on my way out the door. Thanks again for your thoughts.

Strange behavior of std::string find method in SS12

Hi
I faced with strange behavior of std::string.find method while compiling with Sunstudio12.
Compiler: CC: Sun C++ 5.9 SunOS_sparc Patch 124863-14 2009/06/23
Platform: SunOS xxxxx 5.10 Generic_141414-07 sun4u sparc SUNW,Sun-Fire-V250
Sometimes find method does not work, especially when content of string is larger than several Kb and it is needed to find pattern from some non-zero position in the string
For example, I have some demonstration program which tries to parse PDF file.
It loads PDF file completely to a string and then iterately searches all ocurrences of "obj" and "endobj".
If I compile it with GCC from Solaris - it works
If I compile it with Sunstudio12 and standard STL - does not work
If I compile it with Sunstudio12 and stlport - it works.
On win32 it always works fine (by VStudio or CodeBlocks)
Is there any limitation of standard string find method in Sunstudio12 STL ?
See below the code of tool.
Compilation: CC -o teststr teststr.cpp
You can use any PDF files larger than 2kb as input to reproduce the problem.
In this case std::string failes to find "endobj" from some position in the string,
while this pattern is located there for sure.
Example of output:
CC -o teststr teststr.cpp
teststr in.pdf Processing in.pdf
Found object:1
Broken PDF, endobj is not found from position1155
#include <string>
#include <iostream>
#include <fstream>
using namespace std;
bool parsePDF (string &content, size_t &position)
    position = content.find("obj",position);
    if( position == string::npos ) {
        cout<<"End of file"<<endl;
        return false;
    position += strlen("obj");
    size_t cur_pos = position;
    position = content.find("endobj",cur_pos);
    if( position == string::npos ){
        cerr<<"Broken PDF, endobj is not found from position"<<cur_pos<<endl;;
        return false;
    position += strlen("endobj");
    return true;
int main(int argc, char ** argv)
    if( argc < 2 ){
        cout<<"Usage:"<<argv[0]<<" [pdf files]\n";
        return -3;
    else {
        for(int i = 1;i<argc;i++) {
            ifstream pdfFile;
            pdfFile.open(argv,ios::binary);
if( pdfFile.fail()){
cerr<<"Error opening file:"<<argv[i]<<endl;
continue;
pdfFile.seekg(0,ios::end);
int length = pdfFile.tellg();
pdfFile.seekg(0,ios::beg);
char *buffer = new char [length];
if( !buffer ){
cerr<<"Cannot allocate\n";
continue;
pdfFile.read(buffer,length);
pdfFile.close();
string content;
content.insert(0,buffer,length);
delete buffer;
// the lets parse the file and find all endobj in the buffer
cout<<"Processing "<<argv[i]<<endl;
size_t start = 0;
int count = 0;
while( parsePDF(content,start) ){
cout<<"Found object:"<<++count<<"\n";
return 0;

Well, there is definitely some sort of problem here, maybe in string::find, but possibly elsewhere in the library.
Please file a bug report at [http://bugs.sun.com] and we'll have a look at it.

Dreamweaver CC and Windows 8.1 - Can't Find A Valid Editor For This File Extension

Was running the latest version with no issues and then I loaded Office 2013 .. Now when I am in the remote site and try to double click on a .cfm file, I get a dialog box..Can't Find A Valid Editor For This File Extension..
I tried the support chat and they said Dreamweaver support was not available, try again later???
So I thought I would reinstall the CC version and now I can see the Dreamweaver icon next to the files but still ... can't open the file..
Any assistance would be appreciated?
Leo

The issue is only in Windows 8.x where when Dreamweaver CC is installed, it is not able to turn on the file type associations by default. The workaround for now is to manually add the extensions both within Windows and then within Dreamweaver CC itself.
Go to Control Panel > Programs > Default Programs > Set Your Default Programs and select Dreamweaver CC and then select 'Choose defaults for this program' and Select All or the extensions you want to open in Dreamweaver CC
Start Dreamweaver CC and go to Edit > Preferences > File Types/Editors and add '.cfm .cfc' to the extensions and then add C:\Program Files (x86)\Dreamweaver CC\Dreamweaver.exe then click on Apply and Close
That should be it.

Strange behavior of WindowsIntune / Win8.1 : Repetitively launch C:\Program Files\Microsoft\OnlineManagement\Updates\Bin\omupdclt.exe

Hi,
After moving from Win8 to Win8.1 (using WindowsStore update),
I observed sometimes that some command prompt Windows (ugly black MSDOS Windows) opens / closes Repetitively in my desktop.
At a moment where the computer was really busy, I was abble to see the title of this black window :
It was : C:\Program Files\Microsoft\OnlineManagement\Updates\Bin\omupdclt.exe
Can someone tell me how to prevent this strange behavior ?
Thanks in advance.
AC Soft.

I have also openned a case at WindowsIntune support, and up to now, they replyed me this :
We have been able to reproduce this issue ourselves. We are currently working with our engineers to identify if there is a way to prevent these command prompts from launching.
So, while waiting, I Tried your solution.
On the Win8.1 computer that had the problem, i found an AccoundID value, with { }, and all letters in Uppercase, as described in your solution. So, the problem for me is not that AccountID is not populated...
When I looked at another Win8.1 computer that had not the problem, i found an AccountID value
without { }, and with all letters
in lowercase.
So I looked at a Win7 Virtual machine that was enroled into intune too, and that obviously didn't had the problem, and I found there an AccountID value without { }, and with all letters in lowercase, same as on the working computer.
So on the computer that had the problem, I removed the { }, put all letters in lowercase, then run
%ProgramFiles%\Microsoft\OnlineManagement\Updates\Bin\omupdclt.exe /agentupdatenow
I rebooted the computer, and now, I wait to see if the problem is solved...
I will tell you what happened in some days...
AC Soft.
That process will not fix this issue. We have a fix coming in an upcoming service release.

Permanently Hiding a specific File Extension in Finder

Hello peeps,
is what I'm asking for possible? What I have in mind is having it so that all images (png, jpg, etc.) in the Finder don't show their file extension. Is there a way to do this?
Thanks, -temhawk

It doesn't seem to be possible. I will have to hide my extensions manually, although that is easy and quick in most cases.

Changing file extensions disables any finder keyboard input

Hi all,
Well, i just said it. Oftentimes (very often) when I change a file extensions, after clicking yes to the most annoying confirmation dialog a web designer can find on OSX, the finder stops receiving any input from the keyboard.
What happens is that after the extension change, I can select file names and do everything the mouse can do in the finder, but no keyboard input is received, I just cannot type any character whatsoever.
Anyone with the same problem? A solution? A hint?
I'm on Tiger 10.4.5, xtools2 installed.
PowerBook G4 15'' 1GHz (512MB RAM) Mac OS X (10.4.5) iPod 3G (40GB), External FireWire HD (20GB)

Have you tried trashing Finder prefs? Navigate to ~(yourhome)/library/preferences and trash these two files:
com.apple.finder.plist
com.apple.sidebarlists.plist
Then log out and back in again. Or restart.
(You will have to reset a few finder prefs the way you like them.)

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?

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.

DW CC: Can't find a valid editor for this file extension

Hi,
I am using dreamweaver cc for 1 month now. I have been having difficulty opening .asp file.
In the File panel, when i click on one of the asp files, the error message is 'Can't find a valid editor for this file extension'.
To solve this problem, I will right click on the file and choose Open with > Dreamweaver.
However, this is very inconvenient. Someone pls help!

You can configure that in your Operating System. In my version of Windows XP, open any folder and select TOOLS/FOLDER OPTIONS/FILE TYPES then scroll to the asp file type and select DW as the editor.

Can't find a valid editor for this file extension

Support for ColdFusion and other databases were removed from DWCC. You can add them back with the Legacy Extension, or adding a paid extension from DMX Zone...
About 1/2 way down this page for the legacy extension: http://blogs.adobe.com/dreamweaver/
It's a paid extension, but adds back a lot of the things that were removed...

.jpg file extensions - how to find/add?

Hi, all:
Kind of a noob question... when I switched from the Dark Side, I imported all of the photos that were on my PC into my Mac. For whatever reason, the .jpg file extension was not appended to those photo files, and so iPhoto does not display them in its "Info." I only see the filename itself, not the ".jpg" part (iPhoto does display the .jpg extension for all photos I downloaded into iPhoto).
So, my two questions are:
1) Where/how can I find the individual files that are in my iPhoto library, so that I can see which ones do not have the extension?
2) Is there an easy way to add the .jpg extension to each file that doesn't have it, an app, or shareware, or something? Renaming 2,000+ individual files does not appeal to me...
Thanks!
Bill in CT

You can't add the jpg extension once the photo has been imported into iPhoto. It needs to be done before you import. If you add the extension to photos already in the library that's the same as changing the file name and will break the file path to the original file. You will get the dreaded "!" if you try to edit or use the photos in a book or slideshow.
You really don't need to add the extension for iPhoto to operate correctly. If you need the photos outside of iPhoto and need them to have the extension you can export them out of iPhoto via the File ➙ Export ➙ File Export menu option. Set the Format = JPEG with the other settings as you see fix and you'll get the new files with the .jpg extension.

How to find files by extension in Finder or Spotlight?

Hi.
This is shame but I was faced with problem which I can't solve in Finder/Spotlight — I can't search files by extension. May be I don't know something? Keyword "Kind" too abstract for this and searching not by exact extension. Wildcards never worked in spotlight. Thoughts?
P.S. Yes, I can do for example in terminal 'find . -name "*.txt" | xargs open -a BBedit' but this is not working for all apps and I don't want to return to eighties

dusty thread, but for those arriving from google, it is (supposedly) possible to add File Extension to the search options available:
in Finder hit Cmd+F to open the Spotlight interface (without requiring a string to search for)
Hit the search parameter dropdown (by default "Kind")
Select 'Other'
Find and tick 'File Extension' from the list to have it show up in the short list.
I say 'supposedly' because its not working for me when i search for 'psd' on 10.8.2
Hope it helps someone, Cheers, Tim

Strange behavior with csv flat file integration

Hi,
i've a real strange behavior with csv flat file integration.
I've defined the file inbound with | as separator
Here is the sender payload result, extra columns appears !
<row>
<VAL1>D</VAL1>
<VAL2 />
<VAL3>01</VAL3>
<VAL4 />
<VAL5 />
<VAL6>003160000</VAL6>
<VAL7 />
<col>003160001</col>
<col />
<col>2</col>
<col />
<col>91200604212</col>
<col />
<col>VIRTUAL DJ HOME EDITION</col>
<col />
<col>2</col>
<col />
<col>2</col>
<col />
<col />
<col>2</col>
<col />
</row>
When i changed the separator to ; in my file and in the file inbound it gives the following.
Everything is ok.
<row>
<VAL1>D</VAL1>
<VAL2>01</VAL2>
<VAL3 />
<VAL4>003160000</VAL4>
<VAL5>003160001</VAL5>

<col>VIRTUAL DJ HOME EDITION</col>
<col>10</col>
<col>10</col>
<col />
<col>10</col>
</row>
Why using a different separator would change the payload ?
It will be a good thing for me if I could use the pipe separator.
Thanks

Can you give the steps you're using to get this error? I'm not seeing any problem here.
1) Create a new audio project (44.1 KHz).
2) Arm the record head in track 1 by pressing the "R" button in that track. Verify audio levels.
3) Record by pressing the record button in the audio controls.
4) Stop recording by pressing the stop button.
5) Play back the resulting audio. Sounds fine.
6) Select File > Export.
7) Change the file format to WAVE file. Change the bit depth to 16 bit, change the sample rate to 44.1 KHz.
8) Type the name SAVETEST.wav and click on the Export button.
9) Play back the resulting WAV file in QuickTime Player, Apple Loops Utility, etc. and it seems just fine.
What am I missing that you're doing?

Smart Folders - Finder - multiple file extensions

Hi All,
I'm only a couple of years into iOS so please forgive me if this is a really dumb question but:
When I create a smart folder in Finder I can't seem to add a second search criteria without the original information disappearing.
As an example: If I search for 'file extension' and '.docx' over the past seven days the search functions correctly.
If I search for 'file extension' and '.doc' over the past seven days the search also functions correctly.
If however I try to add both searches together for the same smart folder so that I can see both document types i've been using over the past 7 days then it returns a blank folder. Surely i'm doing something wrong and I don't have to have two different smart folders for each file extension?
Thanks in advance!

Create a new smart folder by going to "File > New Smart Folder" or pressing "⎇⌘N" and create the first parameter.
Hover your mouse over the ( + ) button on the right.
Hold down the Option "⎇" key and the ( + ) turns into an ( ... ).
Clicking this allows you to change "All" to "Any" and enter the file extensions you want.

Need help " Can't find a valid editor for this file extension" not sure why I am getting and this or what to do.

also say explorer not reading SWF files and I have to reload them? Not sure what that is either,
