Extract text from ES2 files
To convert your ES2 file to another format, you need E-Prime 2.0 or other Developer software.
To convert other file formats to the "Behavioral Research Script" file type, you need software like E-Prime 2.0 or a similar tool.
The .ES2 file extension represents a specific version of an experiment design script used by E-Prime 2.0, a leading software suite for behavioral research and psychology experiments developed by Psychology Software Tools. These files contain the complete structural logic of an experiment - including timing, stimuli presentation, and input collection parameters - created within the E-Studio interface.
While .ES2 files are the backbone of research design, they present significant hurdles for collaboration and archiving. The primary difficulty is the proprietary lock-in: opening an .ES2 file natively requires a valid E-Prime 2.0 license and a hardware protection key (dongle). This makes it nearly impossible for students, collaborators, or peer reviewers to inspect the experiment logic without having the expensive software installed. Furthermore, version incompatibility is a frequent headache; .ES2 files must be explicitly converted (upgraded) to ES3 to work in newer versions of E-Prime, and they cannot be opened at all in legacy E-Prime 1.0 environments.
For researchers looking to document, share, or archive their work, the best conversion target is PDF (for visual flow documentation) or XML/TXT (to expose the internal script structure). Converting to XML is particularly useful because the underlying architecture of .ES2 files utilizes XML data structures, allowing technically inclined users to parse experiment parameters without the original E-Studio interface.
Convert.Guru analyzes your ES2 file, detects the exact format, and lets you read the text inside.
Users also converted ES3, ES and PXP files.
If you want to convert ES2 file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use E-Prime 2.0 or similar software from the "Psychology Experiment Design" 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 ES2, try E-Prime 2.0 or another comparable tool in the "Psychology Experiment Design" 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 ES2 converter.
