What is an MCA file?

MCA files mostly belong to Minecraft by Mojang. An MCA file is a virtual world in Minecraft world construction video game. MCA (Minecraft Anvil) format was introduced in Minecraft 1.2.1 update to replace MCR (Minecraft Region) format. Compared to the older MCR world file, MCA supports double the maximum build height (previously 128), dynamic loading of world sections, and increased block ID size. Another type of MCA file contains GPS data used by PC Navigator software. MCA is also the filename extension of an audit cost report created by Medicare Auditor.

How do you open MCA files?

You need a suitable software like Minecraft to open an MCA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MCA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MCA file directly in the browser:.

MCA format details:

To find out what program is needed to open MCA files, you need to determine the file format. The file format can be determined based on the file extension and the signature (the first few characters of a file). 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. Our evaluation of the MCA files is as follows:

The MCA file extension is used very often and includes many different file formats. The following file formats are most commonly found in MCA files:

8% of all MCA files have the same signature <<PMCA SPECTRUM>>. The contents of these files are partially readable by a human. The file size is in the range of 3 KB to 11 KB. This file type is new and state-of-the-art. The following keywords are characteristic: <<PMCA SPECTRUM>>, REAL, LIVE_MODE - 0, DESCRIPTION -, TAG - live_data, SERIAL, GAIN - 2, THRESHOLD - 0, PRESET_TIME - 0, 000000 and START_TIME - 09. Files like these are sometimes connected to group and dist.
6% of all MCA files use the same file format, which can be identified by the letters "00 01" at the beginning. The contents of these files cannot be read by a human; only a computer program can interpret the data. A typical file size is 4 MB. Some examples of file names are r.0.0.mca or r.-1.-1.mca.

The remaining 86% of all MCA files are different files with different signatures, such as MADP. They are often associated with sounds or archivetempr. Just click the "Choose your .mca file to analyze" button on this page to find out what your MCA file is.
