Extract text from Capture One session files (COSESSIONDB)
To convert COSESSIONDB session files to another format, you need Capture One or other Database software.
To convert other file formats to the "Capture One Session File" file type, you need software like Capture One or a similar tool.
The .cosessiondb file is a database utilized by Capture One (originally developed by Phase One) to manage professional photography sessions. It stores vital project data, including parametric image adjustments, color grading settings, metadata, ratings, and relative file paths. It operates in tandem with physical folder structures (Capture, Selects, Output, Trash) to keep commercial photo shoots organized.
A major disadvantage of the .cosessiondb format is its strict dependency on Capture One. It is a proprietary data structure that requires an expensive software subscription to open and utilize properly. Furthermore, users often mistakenly believe the file contains actual photographs. It does not. It only holds the parametric edits and database pointers. If you attempt to send this file to a client without the accompanying RAW files, they will see nothing.
Because of this closed structure, standard online image converters will fail to process a .cosessiondb file. They look for pixel data, which this database entirely lacks. Converting the actual image edits to another raw processor like Adobe Lightroom usually requires native import plugins, and even then, proprietary color grades are often lost or poorly translated. If you need to extract the raw text data, target formats like SQLITE, CSV, or TXT are the most realistic options, though this will only yield database tables, not rendered images.
This file format is difficult to open or convert because only the original software's proprietary image engine can properly read or export the visual data. Because it is built on a standard SQLite architecture under the hood, our tool can inspect the internal file structure and show text or internal database content. If our analysis detects a supported underlying format, viewing tables or extracting metadata text may still be possible.
Convert.Guru analyzes your COSESSIONDB file, detects the exact format, and lets you read the text inside.
If you want to convert COSESSIONDB file to DB, SQLITE, SQLITE3, MDB, ACCDB, DBF, ODB, FDB, GDB, MYD, FRM or SQL, you can use Capture One or similar software from the "Photo Session Database" category. In the File menu, look for Save As… or Export….
To convert NDF, SQLITE3, BAK, RDB, SQL, DB4, MDF, MDB, LDF, DB, DB3 or SQLITE files to COSESSIONDB, try Capture One or another comparable tool in the "Photo Session Database" 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 COSESSIONDB converter.
