About EXD files
The .exd extension represents a collision of three distinct, incompatible formats, creating significant confusion for users. Primarily, these are Control Information Cache files generated by Microsoft Office to store internal data for ActiveX controls. These files are notorious for becoming corrupted after Windows Updates, leading to 'Object Library Invalid' errors in VBA projects. They are binary system files, not documents, and attempting to 'open' them in a text editor results in illegible garbage. However, in scientific and industrial contexts, .exd files are valuable data containers. Heidelberg Engineering uses this extension for ophthalmic retinal scans (often disguised ZIP archives), while Chopin Technologies uses it for Alveograph flour analysis data stored in legacy JetDB (Microsoft Access) databases. Practical constraints are high: the Microsoft files are useless outside the system cache, the Heidelberg files require proprietary viewers or manual archive extraction, and the Chopin files require outdated database drivers to access. For the Microsoft cache, the 'conversion' is actually deletion - forcing the system to regenerate a clean version. For Heidelberg files, renaming the extension to ZIP often allows for the extraction of raw TIFF or JPG images. For Chopin data, treating the file as an MDB allows conversion to CSV or XLSX for modern analysis.
Convert.Guru analyzes your EXD file, detects the exact format, and lets you read the text inside.
If you want to convert EXD file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Microsoft Office or similar software from the "ActiveX Control Cache" category. In the File menu, look for Save As… or Export….

The EXD Converter Story
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 EXD converter.
