.I01 file format is used by DVD Shrink software application. It is a freeware application which is DVD transcoder that is based on DVD ripper.
This application is used to back up data on DVD. The application stores data in number of files which have extension name given to define their sequence. The whole data is divided into several parts depending on the size of the data. The second file in this series of backup files is given extension of I01. These files are created to reduce the size of the data on DVD with minimum possible loss in quality. The software uses VBR encoder and DeCSS decryption algorithm.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .I01 file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .I01 file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .I01 file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .I01 extension. Directly on this website you can find a solution of the most common problem with the .I01 file – that you do not have on your computer the appropriate program to open the file.
