I have a data file with 2 time epoch and i am successful in finding the difference in seconds and i saved that difference in seconds a different file they are in float and only 1 column. So now i have to find the CDF and CCDF of that time difference. – Phani.lav Jul 8 '14 at 18:27.
Examines a CDF file and provides methods to access its records.
Constructing an instance of this class reads enough of a file to identify it as a CDF and work out how to access its records. Most of the actual contents are only read from the data buffer as required. Although only the magic numbers and CDR are read during construction, in the case of a file-compressed CDF the whole thing is uncompressed, so it could still be an expensive operation.
For low-level access to the CDF internal records, use the
getCdr()
method to get the CdfDescriptorRecord and use that in conjunction with knowledge of the internal format of CDF files as a starting point to chase pointers around the file constructing other records. When you have a pointer to another record, you can use the record factory got from getRecordFactory()
to turn it into a typed Record object.- Since:

CdfReader
- Constructs a CdfReader from a buffer containing its byte data.
- Parameters:
buf
- buffer containing CDF file- Throws:
java.io.IOException
CdfReader
- Constructs a CdfReader from a readable file containing its byte data.
- Parameters:
file
- CDF file- Throws:
java.io.IOException
Method Detail |

getBuf
- Returns the buffer containing the uncompressed record stream for this reader's CDF file. This will be the buffer originally submitted at construction time only if the CDF does not use whole-file compression.
- Returns:
- buffer containing CDF records
getRecordFactory
- Returns a RecordFactory that can be applied to this reader's Buf to construct CDF Record objects.
- Returns:
- record factory
getCdr
- Returns the CDF Descriptor Record object for this reader's CDF.
- Returns:
- CDF Descriptor Record
isMagic
- Examines a byte array to see if it looks like the start of a CDF file.
- Parameters:
intro
- byte array, at least 8 bytes if available- Returns:
- true iff the first 8 bytes of
intro
are a CDF magic number

What is a CDF-MS file?
Cdf-ms File Reader
Files with the .CDF-MS extension contain properties – namely parameters such as app name, version, description, implementation options, and relations needed to launch the Windows system app using the ClickOnce technology. CDF-MS files are compiled versions of MANIFEST files, which makes the use, processing, and analysis of the data they contain quicker.
The ClickOnce technology, developed by Microsoft, uses these supporting CDF-MS files to launch Windows software simply by having the user click on a certain link located on a webpage. Manually modifying or deleting CDF-MS files may therefore decrease the stability of the ClickOnce tool.
Program(s) that can open the .CDF-MS file
How to open CDF-MS files
If you cannot open the CDF-MS file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports CDF-MS among those that are installed on your device.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the CDF-MS file can be found in the table. Now just download and install the appropriate application.
Possible problems with the CDF-MS format files
The inability to open and operate the CDF-MS file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the ClickOnce Deployment Binary Manifest Format file. Below is a list of possible problems.
- Corruption of a CDF-MS file which is being opened
- Incorrect links to the CDF-MS file in registry entries.
- Accidental deletion of the description of the CDF-MS from the Windows registry
- Incomplete installation of an application that supports the CDF-MS format
- The CDF-MS file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the CDF-MS file.
- Drivers of equipment used by the computer to open a CDF-MS file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the CDF-MS file should operate with your programs without any problem. If the problem with the CDF-MS file has not been solved, it may be due to the fact that in this case there is also another rare problem with the CDF-MS file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.CDF-MS) you have two ways to do it. The first and the easiest one is to right-click on the selected CDF-MS file. From the drop-down menu select 'Choose default program', then click 'Browse' and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the CDF-MS file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. CDF-MS) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
