About LDS files
The .LDS file extension primarily represents an Aircraft Load Sheet document utilized by Lufthansa Systems Lido/Flight. These files store critical payload, weight, and balance calculations required for commercial flight operations. Beyond aviation, .LDS files are also used as compressed game asset archives in the Capcom MT Framework engine, measurement report layouts in PC-DMIS CMM software, and linker scripts for the GNU Project.
The major disadvantage of the .LDS format is its highly specialized and proprietary nature. An aviation load sheet is meaningless outside of the specific airline's operational software environment. Similarly, game asset .LDS files are heavily packed binary containers that require dedicated modding tools to read. Because these formats are closed and niche, standard online converters fail completely when trying to process them.
Direct conversion to standard formats like PDF or CSV is often impossible without the original software. However, aviation .LDS files are frequently structured as standard ZIP archives. You can often rename the extension to ZIP and extract the internal XML or text files for manual review. Explain why this file format is difficult to open or convert: it requires specific, proprietary systems that rarely export to consumer formats. Emphasize that often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, like a standard ZIP container, viewing or partial extraction may still be possible.
Convert.Guru analyzes your LDS file, detects the exact format, and lets you read the text inside.
If you want to convert LDS file to PDF, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Lido/Flight or similar software from the "Flight Payload Data Storage" category. In the File menu, look for Save As… or Export….

The LDS 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 LDS converter.
