How to open an RSF file

RSF file format:

Every file has a defined file format, i.e. how the data is arranged in the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. If there are problems opening a file, you must first determine the file format used. Below is our analysis of the RSF files:

You will often come across the RSF file type. This predominantly uses a uniform format. The two most popular formats are as follows:

• 70% of all RSF files use the same file format, which can be identified by the letters "êô³" at the beginning. These files contain neither text nor words, but only data. The average file size is 4 MB with most files being between 64 KB and 51 MB in size. The file type was developed only in the last few years. These files are often associated with drive, partition, lost, lostpartitionfiles, drived, media, desktop and recycle.
• 7% of all RSF files start with the bytes CMBK, which are crucial for this file format. These are binary files, so they do not contain words or text. The average file size is 2 MB with most files being between 16 KB and 43 MB in size. Certain words are almost always found in the files, such as CMBK and cstemp.rdf. A usual file name is 2020-06-01 10_30_DRW_CR.rsf or 2020-06-01 10_30_DRW_PR.rsf.

All other RSF files (23%) have no uniform format, often e.g. ZIP and RSF. Sometimes used for result, macintoshhd, drivef, last, macintosh, unknown, drivee, driveh, drivei, disco, data or disk. If you want to find out what your RSF file contains, drag and drop it onto this page.
