RLT file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the RLT files looks like this:

The RLT file extension includes various formats for various programs. However, the following two file formats are common:

• 25% of all RLT files store the data in the FreeArc file format. FreeArc is a modern open source file archiver which narrowly outperformed WinZip, 7-Zip, and WinRAR in its "best compression" mode. The contents of these files cannot be read by a human; only a computer program can interpret the data. A typical file size is 43 GB. The file type is relatively new. The keywords storing and FDT} are typical for these files. Examples of file names are setup-1.rlt or setup-2.rlt.
• 20% of all RLT files start with the bytes "Test Type", which are crucial for this file format. These files are text files, so they contain words and text. The files are often between 290 bytes and 1 KB in size. The following keywords are characteristic: Method Name, Sample name, "Test Type","Tension", Instron, Tensile, User, Users, Documents, INSTRON, Company, Compression, Lab name, Operator ID and im_tens. These files can be linked to tens, comp, krit, reyhanerezaei and urchin.

All other RLT files (55%) have no consistent format, frequently e.g. DOC, RLT, Sample, PTLG and starQuiz. These files are often connected to results, text or quiz. Drag & drop your file here to see the file format and a preview of your RLT file!
