Are you facing any problem in splitting large size of PST files such as 2 GB or 20 GB files? MS Outlook is used worldwide for storing all your email messages and other items of mailbox in an Outlook data file, which is also known as PST or Personal Storage Table. MS Outlook uses two types of PST files: Unicode PST and ANSI PST. ANSI PST is used by the MS Outlook 2002 or earlier versions of it. File format for these Outlook versions is ANSI and the size limit is 2 GB. It means that more than 2GB of data cannot be stored in ANSI PST FILE. And if the file size exceeds this limit then chances of it getting corrupted increases. For UNICODE PST file also the issue is same. UNICODE PST file is used for MS Outlook 2003 and later versions. And UNICODE is default file format for these versions of MS Outlook. But the file size limitation for UNICODE PST is upto 20 GB and for higher versions like MS Outlook 2013 limit is upto 50 GB.

In UNICODE PST file the corruption chances are very low because of its high file size limit; but on exceeding the size it may become corrupted. And if a PST file gets corrupted then you may lose all your crucial emails, and other items of your mail box, that’s stored in the file. In such unfortunate situations corruption of the PST file can be avoided by splitting it into several small sizes. Or you can also compress it for decreasing its size. But what if the PST file will get corrupted before splitting or compressing. Here’s the way to know how to deal with a corrupt PST file of Microsoft Outlook.

Ways To Split Large PST Files

MS Outlook does not provide any function for splitting or breaking large sized PST file into smaller parts. But this action can be performed using “Archive” and “Import and Export” features of MS Outlook. Apart from this MS Outlook also provides “Move to Folder”. This feature is not useful for splitting large files but it can help in moving some items from one PST to other. For eg; an Outlook email consists of thousand emails and you want to split it into smaller parts. So you can move hundred emails into a PST file that will create a new PST file and same thing can be done with remaining. Therefore by doing this ten PST files will be created. And this function of moving PST files into new PST file is considered to be very safe and effective, but good technical knowledge is needed.
