OPR file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. Below is our analysis of the OPR files:

OPR is not a common file extension and does not have a uniform file format. The following file formats are most commonly found in OPR files:

10% of all OPR files use ZIP compression, so several files are combined and compressed into one OPR file. 3 to 14 compressed files with names like RDMetaLog.txt, Reports.zip, info.ini, info.txt, msg.txt, stack.txt and stamm.zip are common. If you'd like to see the images and files included, just rename the file extension to .zip and double-click. The files are on average 120 KB in size and range from 24 KB to 57 MB. The keywords stamm.zip are typical for these files.
7% of all OPR files start with the magic bytes OJPR, which are always the first bytes of this file format. If you open these files in a text editor, you can view the contents and find segments of text. A typical file size is 2 MB. The files contain the following words: OJPR and java.io.FileInputStream.open(java.lang.String)void*,java.io.FileInputStream.read()void*,java.io.FileInputStream.readBytes(byte[],int,int)int*,java.io.FileInputStream.skip(lon.

The remaining 83% of all OPR files are files with no common format, such as JetDB and GZIP. These files are often connected to opro. You can get all the details of your OPR file by dragging it onto this page or by clicking the button "Choose your .opr file to analyze" above.
