Windows Live Messenger creates a number of files like
C:\Users\USERNAME\AppData\Local\Microsoft\Windows Live Contacts{ae86acef-5a45-4447-bc32-521fc9289e1a}\DBStore\contacts.edb
and stores contacts within. When looking on such files, it is obviouos that they have strict structure. However, I failed to find the description of contacts.edb structure in internet.
Does anybody knows this structure? Or maybe there are some parser sources available? (I do not need a exe for that, I know about NirSoft one).
There is a project called libesedb which might be of use here.
The contacts.edb file is an ESEBD file.

I have an app that imports a file (or many files) using the DocumentPickerDelegate. This means that the files imported are likely off of iCloud, Google Drive, etc. I want the app to load any previously selected files on startup, but I'm wondering if this will be possible, since it looks like you lose access to the files once the app closes.
Does anyone know a way around this? For example, are you able to actually copy the imported files to the apps local data?
Thanks for your help!
In the delegate where it gives you the URLs of the selected files you need to make local copies of the files before the delegatecall completes. This is covered in the documentation for UIDocumentPickerController.
I'm very new to using Umbraco, but I am looking for a way to sort the media files so I can see which files haven't been linked to any content yet? e.g. PDFs that are yet to be put onto any page.
Is there a simple way of doing this? Or can someone talk me through step-by-step what to do?
Thanks,
Becky
You can use an extension like https://our.umbraco.org/projects/backoffice-extensions/falm-housekeeping/ to clean out all the unused media.
When working with extensions I would make a copy of your project and test it out on there first as some extensions can be quite temperamental.
In the executable I am reverse-engineering, there are several references to a path in my D:\ drive. However, I do not have a D:\ drive connected. Is it possible that it creates a temporary storage site in the executable?
For example, there is a string:
D:\BuildAgent\...\bin\...\fileIWantToSee.jpg
IDA even believes that the symbol information is in the D drive, and attempts to look for it, to no avail. There are many instances of file references within these strings, and many of them end with a:
Line: **LINENUMBER**
Where would I go about trying to find where this storage is located? Thank you!
EDIT: Could it be in a specific section?
Is it possible that it creates a temporary storage site in the executable?
This is possible. There exists at least one product (http://www.boxedapp.com/, kind of our competitor :) that lets the application create such container -- the calls to file APIs are intercepted by the code added to the application by this product, and this added code handles specific paths in a different way (emulating file operations), letting all other calls go to Windows API.
In order to be able to access iCloud Drive from the application,
I think that we want to use UIDocumentPickerViewController from the application.
but i found following problems when i use UIDocumentPickerViewController.
Cannot upload multiple files at once.
Cannot Download multiple files at once.
When pushViewController from navigationController then display
become strange.
I want to avoid above problems, So is there any another way to get files information from iCloudDrive without using UIDocumentPickerViewController?
like Send some request or query.
I have searched lot and didn't find any query or request to get Files ,Upload files and download files from iCloudDrive.
if you have any idea about this please tell me.
Thanks,
I don't think there's any straightforward alternative, but you could think of...
...using iCloud directly (not iCloud Drive), but then users will only have access to their files from your application
...using Google Drive's sharing extension which supports uploading multiple files at once (the Dropbox SDK probably supports that, too, but their sharing extension doesn't)
...zipping all files before uploading them
...changing the file format so that it's a bundle of multiple files, if you are in control of the file format
...file a radar/feature request, and possibly wait forever ;)
Not sure if that helps, but I don't think you have much of a choice here.
I have a system where users can upload, well, anything really - and these files are available to other users.
I need to come up with a list of file types that are genuinely needed by professionals in different industries that are safe from hacking/viruses, etc.
.doc .docx .gif .jpg .jpeg .mpg .mpeg .mp3 .odt .odp .ods .pdf .ppt .pptx .tif .tiff .txt .xls .xlsx .wav
What other file types do you know of that are both useful and safe?
Clarification
Many of the comments and responses are asking for a clearer definition of 'safe from hacking/viruses' - I ask the question with precisely that level of detail because I don't have as sophisticated an understanding of file types and their risks as many of you do, and I would like guidance on 1) any file types that may keep my site more secure, and 2) if there are no 'safe' file types then any advice on how to move forward with a system that allows for flexible uploading and sharing of files.
If indeed any malicious file can be packaged as a seemingly-safe file, how can I protect my users?
No filetype is safe if the program you use to open it with is badly (or carelessly or evil-y) written.
You can't assume that all files with a given extension is safe from 'viruses'.
I can easily rename a malicious executable to .doc and 'hack' your system.
EDIT:
There is no (simple?) way to check whether a user-uploaded file is malicious or not.
The app that you're creating is no different than any other file sharing websites out there (Rapidshare, Megaupload, etc).
There is nothing stopping anyone to upload malicious files to those websites.
Safe files does not exists. The ordinary text file is safe? For example with content:
format c:
if some program can execute a content of the file... you get the idea.
So, here are not safe files - only restrictions to RUN code (programs). (And I understand if this answer does not like.) :)
For "useful" you'll need to ask your customers.
For safe, there's no such thing because a file extension is just a part of the file name that gives a suggestion of what type of file it is. It need not accurately represent the type, and is easily manipulated.
Rather than protecting based on file type. I would get a 3rd party to virus scan each file on upload. Reject those which are identified as positive.
The list is pretty endless! A quick search finds http://filext.com/alphalist.php?extstart=^A
Well you can include all data files and exlude all executable/script files.
One list of executable file extensions is here: http://pcsupport.about.com/od/tipstricks/a/execfileext.htm
you may look other sources to inprove coverage.
Edit: for second part of the question addressing sequrity-
It would be best to have bunch of anti malware software installed on the server to check each sumbission - they are designed for this specialized task, use them. Anyways no executable file is professionaly useful as long as people are not looking for crackware.
