How to password Protect PDF Documents & increase their value

July 1st, 2010 admin

PDF is a file format for the long-term archiving of electronic documents. Portable Document Format (PDF) is a file format created by Adobe Systems. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a fixed-layout 2D document that includes the text, fonts, images, and 2D vector graphics which compose the documents.
A PDF file may be encrypted for security, or digitally signed for authentication. The standard security provided by PDF consists of two different passwords, “user password” and “owner password”.

A PDF document may be protected by password to open (‘user’ password) and the document may also specify operations that should be restricted even when the document is decrypted: printing; copying text and graphics out of the document; modifying the document; and adding or modifying text notes and form fields (using ‘owner’ password).
However, all operations (except the document open password protection, if applicable) which are restricted by “owner” or “user” passwords are trivially circumvented by many commonly available “PDF cracking” software and even freely online, and thus these restrictions are obviously ineffective in letting the author control what can and cannot be done with the pdf file he or she created, once it is distributed. This warning is also displayed when applying such restrictions using Adobe Acrobat software to create or edit PDF files.

Even without removing the password, most freeware or open source PDF readers will ignore the digital rights management “protections” and will allow the user to print or make copy of excerpts of the text as if the document were not limited with such anti-features.The big advantage that PDF documents have over image files like TIFFs or JPGs, is the ability to secure the document. You can secure PDF documents by password protecting the PDF files or documents. You can also limit a user’s ability to copy text from a PDF document and even prevent a user from printing the PDF document.PDF Protect-Unprotect Tool is a similar kind of software tools which helps users to implement various protections on their PDF files.

How to Convert Microsoft Outllook non-Unicode (ANSI) PST file to a Unicode PST file

July 1st, 2010 admin

Outlook files created with MS Outlook 97-2002 versions are non-Unicode PST files, which don’t support multilingual data. MS Outlook 2003 & above versions offer greater storage capacity for Outlook items and folders and hence supports multilingual Unicode data.

There is no automatic way of converting a Microsoft Outlook 97-2002 Personal Folders file (.pst) to a Unicode-capable Microsoft Outlook Personal Folders file (.pst) file. The easiest way to convert a non-Unicode .pst file is to create a new data file in the Microsoft Outlook Personal Folders file (.pst) format that supports Unicode and then import items from the old data file to the new Microsoft Outlook Personal Folders file (.pst).
Create a new data file

1.    On the File menu, point to New, and then click Outlook Data File.
2.    To create a Microsoft Outlook Personal Folders File (.pst) that offers greater storage capacity for items and folders and supports multilingual Unicode data, click OK.
3.    In the File name box, type a name for the file, and then click OK.
4.    In the Name box, type a display name for the .pst folder.
5.    Select any other options you want, and then click OK.
6.    The name of the folder associated with the data file appears in the folder list. To view the Folder List, on the Go menu, click Folder List. By default, the folder will be called Personal Folders.

Import items to the new data file

1.    On the File menu, click Import and Export.
2.    Click Import from another program or file, and then click Next.
3.    Click Personal Folder File (.pst), and then click Next.
4.    In the File to import box, specify the path and file name of the old non-Unicode Microsoft Outlook 97-2002 Personal Folders File (.pst) file you want to import and click Next.
5.    Select Import items into the same folder in: and select the name of your new Unicode Personal Folders File (.pst).
6.    Follow the remaining instructions in the Import and Export Wizard.
Another way to convert non-Unicode data file (.pst) to Unicode data file (.pst) is to use third party software tool which efficiently convert non-Unicode PST file to Unicode PST file without getting corrupted.
PST Upgrade and Downgrade is the best utility to convert PST file format, i.e.  Non-Unicode PST files to Unicode PST files or vice versa Unicode PST files to Non-Unicode PST files.

Compress or shrink my huge pst file used by Microsoft Outlook

July 1st, 2010 admin

Microsoft outlook is a very popular program from Microsoft office and it used as Personal Information manager worldwide. It can also be used in collaboration with Microsoft exchange server and Microsoft share-point server. MS outlook stored its data in PST (personal folder file).

Over the time PST file become very large and after years of usage it becomes huge. Huge PST file start to develop many more complications despite the robust file format (PST). These complications are as follows:

1. Slow performance of MS outlook as it needs to parse huge PST file.
2. Chances of becoming corrupt due to many reasons which can be a small disk failure or use of any malfunctioning software or virus.

Now you must have understands that there a urgent need to compress the size of MS outlook PST file as critical mails and other information is stored in it and lose of data is painful as it costs a lot of money and time. Slow performance has a very low weight-age as compare to previous issue but still it exists.

Now we come to the point as how to reduce the size of PST file. As all we know that most e-mail’s size usually has 80% data as attachments rest 20% is email content. Now we can hit this portion. There are two methodologies by which we can compress the size of huge PST file.

1. Activate the compression scheme built in MS Outlook PST file. This is very useful in general and easy to deploy but for that one must have some knowledge of internals of PST file or MS Outlook. If you want to know how then go Microsoft knowledgebase and check it alternatively you can find information here. But this might be not as helpful as all attachments will remain inside of PST file.

2. Another process seems more tedious and messy but this will help you most to reduce the size of PST file. This include optionally process of first methodology then open your MS Outlook and manually remove all your attachments from mails to a separate folder to your disk and remove them from your mails. You have to do this for all your emails and all objects of Ms Outlook where attachments can be embedded. Alternatively you can remove them compress them by using zip software and then re-attach them. After completing this process again perform the first method.

The second method is more effective and useful as it can reduce the size of your PST file up to 80% and by combining both methods you can reduce the size of PST file up to 90%. It sounds impossible but it is.

Compress is a unique tool to compress PST files in a fast and efficient manner. PST compress is an award-wining and most widely used software for the purpose of shrinking PST file.

What to do when partition table goes wrong.

May 10th, 2010 admin

This topic contain the information about the partition table and how to perform recovery when partition table goes wrong and your hard disk become inaccessible.

Windows operating system from microsoft allows you to divide your hard disk into various partitions. These partition behave as a seperate disk that can be used to install operating system, other programs and data. Partition table is located at the first sector of hard disk(i.e cylinder 0, head 0 and sector 1). Partition table contains information about sizes and location of partition of hard disk. This partiton table is read by operating system to identify or access the partitions. First sector called Boot record of partition contains information about itself. Each partion entry in partition table is 16 bytes long.Total partition table 64 bytes long. These 64 bytes are the last 64 bytes of the first sector of hard disk. Partition table is limited to a maximum of 4 entries. This represents there is maximum of 4 partition that are primary and can be created on hard disk if number of partitions exceeds than 4 then rest of the partitions are extented partitions. This type helps in minimizing the risk of data loss in case of corruption or malfunctioning of operating system. But sometimes it may happen that partition table goes wrong due to any reason.Under such circumtances partitions and the data present in them become inaccessible.

The 16 bytes of one entry are as follows:

OFFSET    BYTE    DESCRIPTION
0    1    Boot label. Tell computer toboot from this partition

1    1    Starting head

2    1    Lower 6 bits (bit 0 to bit 5) isstarting sector.
Higher 2 bits (bit 6 to bit 7) is the higher bits of starting cylinder
3    1    The lower 8 bits of starting cylinder

4    1    Partition type

5    1    Ending head

6    1    Lower 6 bits (bit 0 to bit 5) isending sector.
Higher 2 bits (bit 6 to bit 7) is the higher bits of ending cylinder

7    1    The lower 8 bits of ending cylinder

8    4    Leading sectors of this partition

12    4    Number of sectors of this partition

Partition table corruption can create many hardships to an individual or organisation when it comes to loosing all the important data that can happen due to various reasons such as virus infection, hardware problem, improper shutdown, human errors etc. Microsoft windows shows various error messages indication corruption of the partition table like boot time errors, boot failure, Blue screen of death(BSOD). some of common error messages that are encountered when the partition table is corrupt are:-
Missing operating system.
Invalid operating system.
Unable to read operating system.
Error loading operating system.

When partition table get corrupt computer does not boots up and all your partitions and data present in partitions become inaccessible . At this point you have two choices one is to replace your corrupt partition table with new one by again installing the operating system but this require formatting of hard disk which will erase all the data present in the hard disk. Another way is to use Windows data recovery software and recover data of every partition . Windows data recovery software do not perform any write or deletion operation on your original data it performs recovery in read only mode and makes the fresh copy of data. And after recovering all data reinstall the operating system.

Windows data recovery software from SysInfoTools is a best software for this and many other type of situations. using this software you can recover data of hardisk having FAT16, FAT32 or NTFS file system easily.

what to do when ZIP File get corrupted !

May 3rd, 2010 admin

Zip file is a most popular file compression file format in use. Zip file helps in saving the storage space and also helps in sending the large file over internet through mails. Zip files are created using WinZip utility. It can Compress files upto 50 to 90 percent depending on the file type. When dealing with large file people generally compress them to save save space or to send file through email overinternet. Zip file are easily transfer over internet in less time through this the recipient of the zip file also posses the benefit of instant download. But the recipient must have the software to unzip the zipped file. However, Zip files are benificial from every aspects but the drawback is that sometimes zip files gets corrupt and files or data present in the zip file becomes inaccessible. When you try to extract data from corrupt zip file the extraction process get terminated in the half-way showing some errror message like “The Compressed (zipped) Folder is invalid or corrupted.”.

A zip file can get corrupt due to many reasons and one of them is oversizing of zip files. When a zip file is created exceeding size limit of 2GB problem occurs the data or files present in zip file become inaccessible due to corruption of zip file.  WinZip allows creating of zip files of maximum 2GB size and when this size limit exceeds Zip file becomes corrupted and the data or files present in zip file become inaccessible. Usually this problem does not occur at the time of creation of zip files and there is no error message showing exceeding size limit. The problem occurs when zip file having size more than 2GB is sent to other and when they extract the zip file they fails.

There are numbers of other reasons for the corruption of zip file such as application malfunction, virus infection, CRC errors, improper compression and many other similar reasons. When the corruption of zip file occurs because of any of reason it becomes inaccessible because WinZip cannot verify stored data and thus cannot extract it. Corruption generally makes the file header corrupt and thus the archive become unreadable. If ZIP file is damaged, CRC values of the original files of an archive don’t match the extracted ones, the standard tools won’t extract them.

Corruption of zip file is a very critical situation as it may contain valuable data. To overcome this type of situations Zip Repair tool can be used. This tool uses the high end scanning algorithim which scan each and every file present in the corrupted zip and extract them at user defined location.

Zip repair tool from SysInfoTools can handle all type of zip file that are corrupted because of any of reasons.
