Image file access dates changing in mass (Windows).

In review of the access date properties for image files within a directory being accessed by Bridge within the Favorites area, they are all changing to the current time and date, even if the image is not viewed within Bridge. Why are the access dates of image files being changed even though they are not viewed? This makes it hard to determine whether an image can be archived or deleted based on last access if Bridge is always changing the access date every day. Thanks for any insight you can give on this!

Is there a way to turn off the caching of thumbs or metadata or whatever is causing the Access date to change when searching or reviewing images within a directory using Bridge?
As said, no experience with network environment. But Bridge is a browser and when you want to view things it needs to cache the file and data first.
Having said that, in normal usage (stand alone) it stores and saves this data in the cache folder and once it has done so it will not need to recache until you have made changes to the file. Check Bridge prefs / Cache/ Location to see where the data is stored when you are using this machine.
By default on a stand alone Mac (windows seems to have a similar cache file) it should be in the User Library/ caches/ Adobe/ Bridge CSxx and inhere is a plug in and a folder called Cache, containing several folders.
For Bridge CC there are 4 folders, 256 (the cache files of the thumbs) 1024 (containing HQ preview cache files) data (what it says) and full (containing the 100% previews in cache)
All files that have been fully cached (pointing to a folder the content window should show already good thumbs and the activity bar bottom left in Bridge window should not show any activity, only the number of items showing and items hidden) don't need to recache for that machine again unless you changed something to the file or added metadata.
So once cached there should be no reason for Bridge to 'access' the file again unless access means looking for the file to check if the saved data still applies to the corresponding file on your machine, but then al files should show about the same access time because this is a very fast process on a fast machine.
You can't deselect cache because as said Bridge is a browser showing the content of your files, and to show this it has to generate a thumb and if needed a preview. But as also said, once cached it normally should not start recaching until changes are applied.
You have several ways to set the quality of the cache:
There are two checker board icons top right that give you the option to set for cache. By default it is set to 'Always HQ' to have both good thumbs and a good preview when pointing to a file.
Then you also have to option to generate 100 % previews which provides you with almost instant 100 % previews for loupe in preview panel or full screen view and click. Logically this needs more time and generates a lot of big cache files, all depending on the files you start with and the size of your monitor.
Finally you have the option to use embedded previews only. This is a very quick method but provides low quality thumbs (black border around it) and when clicking on a thumb it first needs to generate a HQ preview that then will take time.
In Bridge prefs advanced there is the option to create also monitor sized previews which should provide you with good quality full screen when using space bar in Bridge to preview in full screen.
This setting also creates a bit larger cache files in the 1024 folder depending on the size of your monitor (logical).
And if you want to apply a search using the find command you also have to include non indexed files to search in all folders, including the not before cached files.
Like first time cache this first indexing takes some extra time but should only need to be done once and then be persistent until you add new files or folders that have not been cached or indexed before.
Until so far the theory for a stand alone. If you have the files stored in a Network and other stations have access and have different cache settings or monitor size settings there might be some other things going on, or someone else has changed the file on their station and then when you select that folder Bridge needs to recache the changes.
Hopefully this makes some sense for you?

Change file access date

Anyone know how to change a file's access date? There is setLastModified() in the File class but I don't see anything for access date.

a\Access date is just the date you last opened it. To set it, you can open it, and it will set it to todays date.

Student file & master data change according to authority

Deal all,
I have following requirements about student file and master data that certain IT are not displayed when i do not have authority.
for example, if A student is belong to my department, IT1702 must be dislayed but student B is not belong to my department IT1702 must be disabled or must dissappear.
if i can adjust student file & master data according authority (student belong to my department or not) it would be very nice.

Hi,
The authorizations checks in Campus Management consist of the basic authorization and the structural HR authorization.
The basic authorization determines whether the user is allowed to execute a certain function, while the structural authorization determines the objects for which the user is allowed to execute this function. In other words, the basic authorization defines what function the user is allowed to use, and the structural authorization defines for which objects the user is allowed to use this function.
For example, the basic authorization can define that the user is allowed to perform the create module booking activity. With the structural authorization you can restrict this activity only to modules offered by the faculty of Mathematics, for example. (The user can then access these modules whenever required; see also Structural Authorization).
Basic Authorization
In release CM 4.64, three authorization objects are used in Campus Management:
At the first level is the transaction code check. The system performs this check each time the user starts a transaction using the menu or command line. For this check to be successful, the user requires an authorization for the relevant transaction code in the authorization object S_TCODE.
At the second level, the Campus Management function is divided into two parts. The first part includes activities such as create request, create registration, create re-registration, cancel module booking, and so on. The second part covers master data like student master data and a major part of the academic structure.
When checking the authorizations for master data, the system uses the HR authorization object PLOG for master data authorization checks. A new authorization object ( P_CM_PROC) has been implemented for activities in release CM 4.64. The system now only checks whether the user is authorized to use the activity. It no longer checks if the user is authorized to read or change the data in this activity. The new authorization concept has the following advantages:
It simplifies authorization assignment. The system no longer uses the comprehensive data model with its many objects and object interrelationships as the basis for the activity authorization (authorization assignment via authorization object PLOG);
Changes in the data model have no effects on the authorization checks for activities;
It is now possible to distinguish between create and change operations, for example in re-registrations;
You can now distinguish between re-registrations and leaves of absence.
The table T7PIQPROCESS (Activities) contains all Campus Management activities. The system performs authorization checks for all activities with the exception of the ones listed below.
Authorization checkes are not performed for the following activities:
AC10 (Send Reminder for Outstanding Payments)
HSMA (Create Status Indicator Manually)
PR11 (Create Applicability List Automatically)
These activities do not contain any activity-related authorization checks.
In the standard system, the authorization check for activities is independent of the objects for which the activities are performed, and of their attributes. (The structural authorization only restricts the objects which the user can then process irrespective of the activity.). If you require additional checks, you can use the business add-in HRPIQ00AUTHORITY.
Structural Authorization
The structural authorization enables you to define the set of objects the user is authorized to process. You determine these objects using evaluation paths. You can define whether the user should only be given a display authorization for these objects or a maintenance authorization as well.
You cannot combine the structural authorization with the basic authorization. The user is therefore authorized to process the assigned set of objects irrespective of the function (s)he is currently using.
Further notes
As functions from other applications areas (Training and Event Management, Notification Processing) and from Student Accounting are integrated in Campus Management, users also need authorizations from these areas.
Campus Management contains a number of roles which you can combine with the roles of other application areas to create composite roles. You can either assign a composite role or individual roles to users.
Component Prefix of the roles provided
Campus Management SAP_CM_
Training and Event Management SAP_HR_PE
Notification processing SAP_CA_NO_NOTIF
Student Accounting SAP_FI_CA_
You create the business partner authorizations in separate IMG activities which you can find in Customizing for Campus Management in Campus Management Master Data -> Students -> Students as Business Partners -> Basic Business Partner Settings -> SAP Business Partner -> Business Partner -> Basic Settings -> Authorization Management.
In the SAP Reference IMG under Basis Components -> System Administration -> Users and Authorizations, you can find more IMG activities in which you can make general settings for authorizations.

File mod date changes on all contents of user homes

I've got network home directories shared over AFP in a small office on 10.8 mac mini server. Whenever a user logs in in the morning, all the files in his/her home directory change modification dates to the time of login. Any ideas why?
Not sure what further details would be useful here - other than that it happens to all the network users, every morning they log in.

So what to do about 25,500 photos dating back to 1999 all changed to Feb 2 2010?
I can't solve your underlying problem, but I wanted to point out that there probably are utilities that will - on a batch basis - change these file dates back to whatever you want.
If you lived in the Mac world, I'd point out that iPhoto - the Mac photo cataloging application - will reset the dates and times of selected photos to whatever you want. So you could select folders or groups of pictures and reset their dates.
Go to Google and see if there is a Windows-equivalent utility. When I do a search like this on Google, I try to imagine what words or terms would be used in the product description, or on the developer's web page. Here, I'd choose "reset date" and "pictures" and "file" and "Windows".
This won't help you solve the underlying problem, but it might help you afterwards.
I've started keeping an old backup hard disk in my gun safe, and only updating it in June and December. That gives me six months to discover that something catastrophic has gone wrong with some of my files - or pictures.
I keep two other backup hard drives that I exchange on a weekly basis. I could see me corrupting the relevant files on both of my weekly backup drives before I realized that I had a problem. Hence, the need for a third long-term hard drive.
Sure, an extra hard drive will cost you $50 to $100. How much time will you have to spend trying to recover from this?

When I move a file the date changes to the current date

I have old files that I moved from a pc to a jump drive then to my mac. It seems like sometimes the modified date seems to change on its own. Sometimes it changes the update date if a file is renamed, but sometimes all it takes is moving the file.
It frequently happens when I move pictures.
Any ideas?
Thanks

Trash Permission Error
Trash Permission Error (2)

Image file can't be opened by windows store app if the file is in the Ext4's external hard disk.

My question is described below:
I have two disks, external hard disk and removable disk. They are formatted with EXT4.
I put the same image in the disks, and use Ext2Fsd to mount the disks.
I open the file in win8, and it will default open by the windows store app : photos.
It will be success to open if the file is in the Ext4's removable disk.
It will be failed to open if the file is in the Ext4's external hard disk.
I don't know why it will be failed to open if the file is in the Ext4's external hard disk.
Does anyone have similar experiences?

Hi hatasum,
Thanks for posting!
Base on my experience, if installed Ext2Fsd, we can read the ext4 file system on windows system. But Which version of Ext2Fsd did you use? From my experience, Ext2Fsd is not spported fine about windows 8 version. Please refer to this software official
website (http://www.ext2fsd.com/ ) . I suggest you could post this issue to the Ext2Fsd discussion forum ( such as
http://sourceforge.net/p/ext2fsd/discussion/143329/thread/7f262ad0/ )for better help.
Thanks for your understanding.

Location of File Containing Data for "reopen all windows from last session"

I'm a heavy-duty Safari user and usually keep 100+ tabs and windows open, carefully invoking the command "reopen all windows from last session" each time I restart. Unfortunately, I screwed up today and started and quit Safari without invoking "reopen all windows from last session," and all of my open tabs and windows are gone.
I can recover the tabs manually using my history listings, but there must be an easier way: the information about the last session has to be stored somewhere. I did a Deja Vu backup on Friday and today I copied the files /~user/Library/Preferences/com.apple.Safari.plist and all the files from /~user/Library/Safari, including HistoryIndex.sk, History.plist, and LastSession.plist, from my backup to my hard drive, but the result was unchanged (that is, my 100+ tabs and windows were nowhere to be found).
Given the time it takes for Safari to shut down, I assume it's storing a large history file somewhere, if only I knew where. Does anybody out there know or could otherwise help my recover from my stupidity?
Thanks in advance.

(proud Mac user for 23 years)

I found a work-around. Since I frequently quit Safari and "reopen all windows from last session" upon restart, my history reflects all of the open tabs and windows contiguously. I thus reloaded the history file, invoked the command "History --> Show All History," found the most recent such contiguous history listing, shift-clicked and selected all relevant listings, and then double-clicked. All of my formerly open tabs and windows were reopened in tabs within a single window. I had to go back and rearrange things but it was far simpler than manually reopening all of those tabs and windows.

DNG file modification date not changed by writing metadata?

I use LR 2.7 on Windows XP.   To my surprise, I just noticed that writing metadata updates (e.g., new keywords) from LR to the DNG files does NOT appear to update the file modification date, which suggests obvious issues for backup strategies (yes, I understand that a changed modification date introduces other backup issues).   I have verfifed that the metatdata does indeed change in the DNG files, so I am mystified.   Can someone shed some light on this?   Thanks.
js
www.johnshorephoto.com

Yes, I explicitely invoke "save metadata to file".   Furthemore, I have checked the behavior by (a) modifying DNGs in LR; (b) saving the metatdata to the DNG; (c) creating a new LR catalog and importing the revised DNGs.    The metadata changes do show up in the re-imported DNGs (and the metadata field "Metadata Date" correctly shows the recent change). Morevover, the file sizes do change (wth the metadata changes) even though the modification dates shown in windows explorer do not change.
However, I just redid the experiment to double check, and discovered an important clue - the mysterious behavior occurs when the DNG files are on a NAS device (in particular a Netgear ReadyNAS Duo.   To summarize:
     - When the DNG files are on a local hard drive, the file modification dates change as expected
     - When the DNG files are non local (i.e., on the network but on a NAS device), the file modification dates do not change even though the file sizes do change;
What's more, I see the same behavior when accessing the DNGs via Adobe Bridge (CS5) - i.e., if I change the metadata, I'm asked if I want to apply the metadata changes to the DNG, and I say yes (and confirm by looking via Bridge at a copy of the changed file).   On a local disk, the file modificaiton dates change (as do the modification date displayed in Bridge), but if the files are on the NAS, the modification dates do not.
Any additional thoughts?

Finder "modified date" changes whenever I view a file

I prefer to list files by date in the finder windows.
Whenever I just open a file without modifying it, the Finder changes it's modified date to Today.
Is it possible to set the Finder to only display actual content modification dates rather than any activity with the file?
Thx,

i've got the same issue....a huge pain. one way to "look at files" without changing the date is to hit the space bar in finder when you're on the file. that will launch the quick look feature and you can see if that's the file you want to open. i know its not the best solution, but a small step. if you find a real way to fix this... let me know.

Dates change from Numbers generated xls file when copy/pasted

I've saved a Numbers '09 file as xls and sent it to an Excel 2003 for Windows user. The file looks great when they open it in Excel 2003. But, when they copy and paste data into a different Excel 2003 file, the date changes about 4 years, which seems to make this a 1900/1904 issue. But why? If Excel 2003 opened up the original xls file generated by Numbers ok, why can't the dates be copy and pasted into another Excel 2003 spreadsheet?

Apple uses a year pattern that starts with the first day of the first leap year in the 20th century.
Microsoft originally adopted a year pattern that began with the first day of the last year of the 19th century (1900) which, although it was a year divisible by 4, was not a leap year.
Later, MS added the 1904 start pattern, but kept the1900 start pattern as well.
What is likely happening in the case you describe is this:
When Numbers traslates the document into Excel format and saves it, Numbers apparenly includes the flag that tells Excl 'use the 1904 start for dates.' Excel open the file, reads the code, and sets the calendar accordingly.
When the Excel 2003 user then copies the data frm that document, the copy picks up only the date serial number(s), and does not get the coded flag identifying which date system is in use.
That data is then pasted into the new Excel document, and with no flag to tell it different, Excel uses its 'normal' setting—the calendar starts on January 1, 1900—and all dates are interpreted as being four years earlier than they were in the original Numbers table or in the first Excel sheet.
I'd assume there is a setting that can be changed in Excel. Where to find it/how to use it would be a good question for an Excel community discussion site. (Although it's possible an answer might arrive here as well.)

Barry

Can I Use Time Machine To Back Up a FAT32 Disk Containing Image Files?

New iMac User Here. I just bought a brand new but mid-2010 27" i7 iMac. Although I've used recent MacBooks when traveling I've got no experience with Time Machine or other similar third party back up software.
I moved to the iMac from a desktop PC running Windows XP Pro SP3. I use the computer(s) mainly for photo image storage and processing. My workflow is based upon Adobe Lightroom (now v3.4.1) and I plan to stick with it. In the PC I had three internal hard drives, 2 of which were dedicated to image files. They were formatted as Windows NTFS. In preparation for the switch I formatted an external drive as FAT32 and copied all the image files to it. Now with the iMac I have Lightroom installed on its internal hard drive but keep the image files on the external hard drive and access them as needed. So far, so good.
The problem arose when I tried to set up Time Machine to back up both the internal hard drive and the external external drive. It will back up the former but not the latter. It tells me it does not interact with FAT32 disks.
Any thoughts, explanations and/or solutions for establishing a simple, single back up routine for both internal and external drives will be most appreciated.

Thanks very much for the quick response. You confirm my intial suspicion, but your suggestion relies on my memory to accomplish on a regular basis (not the best of solutions) and further would be an extended disk run every night because it would not just be backing up new additions but the whole large disk, right?

How can add a images file to anothere image file

hi
Requirement is: i have one image in data base , i is show to user in my application
know we want add another image file in to a current image file (just append)
at end .
i was tried with following code below
i was read the previous(Old) image content from the data base and placed into c:\\ReArchive\\test_content.tiff
ResultSet rs2=dbBean.getSQLRows("select binarycontent from ContentVersion where contentindex="+IndexValue+"");
byte[] bTempData_content=new byte[65536];
while(rs2.next()){
File f = new File("c:\\ReArchive\\test_content.tiff");
f_content.delete();
f_content.createNewFile();
FileOutputStream dest_contentVersion = new FileOutputStream(f_content);
while(rs2.next()){
InputStream is_content=rs2.getBinaryStream("Binarycontent");
nActualRead_content=is.read(bTempData_content,0,65536);
while(nActualRead_content>0)
dest_contentVersion.write(bTempData_content,0,nActualRead_content);
nActualRead_content=is.read(bTempData_content,0,65536);
Then i was took New image file from data base and place in to c:\\ReArchive\\test.tiff");
int nActualRead=0;
ResultSet rs1=dbBean.getSQLRows("select * from Object_Store where Barcode_ID='"+strBar_Code+"'");
byte[] bTempData=new byte[65536];
File f = new File("c:\\ReArchive\\test.tiff");
f.delete();
f.createNewFile();
FileOutputStream dest = new FileOutputStream(f);
while(rs1.next()){
InputStream is=rs1.getBinaryStream("Obj_Content");
nActualRead=is.read(bTempData,0,65536);
while(nActualRead>0)
dest.write(bTempData,0,nActualRead);
nActualRead=is.read(bTempData,0,65536);
then i tried add two images by converting InputStream to String and i am trying add to images
but i was failed ,i think i am in not correct way , how can i solve this problem
thanks advance
gss

File access denied

I'm not really a computer savy so can someone help me please! I tried to install a dvd photoshop cs4 extended and all I got was a pop up auto play window that said " file access denied". I have windows 7 and reading some posts I tried to right click on the .exe to run it as an administrative mode but nothing happens when I right click it. Can someone help ?

You say "nothing happens" when you click on the .exe file, do you not get a context menu popping up?
You could try copying the installation package from the DVD to the desktop and trying from there.

When situation causes Firefox cache file to have Windows modified date more recent than the access date?

I'm reviewing a report from a forensic examination of a hard drive from a Windows machine. In that report are Firefox 3.x cache files where the Windows modified date is more recent than both the Windows created date and the Windows accessed date, with the latter two dates the same. For instance, the modified date might be March 23, 2011 at 10:30 am, and the created and accessed dates might be March 17 at 9:50 pm. What actions, by Firefox, a user, or some other program (other than a date-modification tool) would cause this state of affairs? I'm generally familiar with these dates and under what conditions they change, but have found no doc explaining this particular situation...

In your example,
*the site was originally visited on March 17 at 9:50 pm and the cache entry was created; at that time all three dates should be the same
*the user visited the site again and the information in that cache file was modified on that second visit, March 23, 2011 at 10:30 am
*my experience makes me agree with the first answer in the first link below that accessed timestamp on Windows system is not always accurate; '''''AND''''' accessed timestamp differs for files and folders as defined in the third link below
*See:
