Extract text from Logikal or JRockit files (OPR)
To convert OPR files to another format, you need Logikal or other Data software.
To convert other file formats to the "Project Archive" file type, you need software like Logikal or a similar tool.
The .opr extension is most commonly associated with Orgadata Logikal, a specialized software suite for window, door, and facade construction. These files serve as compressed project containers - essentially ZIP archives - that store technical drawings, calculations, and reports. A significant friction point for users is the proprietary nature of Logikal; without a paid license, stakeholders (architects, clients) cannot view the contained estimates or cut lists. However, because the underlying structure is a standard ZIP container (often holding a stamm.zip and XML data), users can frequently access the raw contents by simply renaming the file extension from .opr to zip.
A secondary, legacy use of the .opr format is for profiling data generated by Oracle JRockit (specifically the Mission Control tool). These files contain serialized Java objects recording server performance metrics (heap usage, method profiling). These are strictly for developers and require the Oracle JRockit Mission Control suite to visualize; they are not human-readable in raw form. For archiving or sharing, users typically extract Logikal contents to PDF or Excel, or export JRockit data to CSV or XML.
Convert.Guru analyzes your OPR file, detects the exact format, and lets you read the text inside.
Users also converted DEFI, ORC and EXEC files.
If you want to convert OPR file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Logikal or similar software from the "Construction Project Data" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to OPR, try Logikal or another comparable tool in the "Construction Project Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our OPR converter.
