I host a Minecraft 1.8.8 server and I checked my world folder. I went into the DIM and DIM-1 folders and I see .mca
files and .mcr
files.
What is the difference between these two file extensions?

.mcr (McRegion) files are part of the older format, where as .mca (Anvil) is a newer format and was introduced in 1.2.1 update to the Java Edition. Main differences are:
If you see both files, what this means is that your old world files were converted to the new format, but in compatibility mode (hence why old files are left behind). If you wish to save space or reduce backup size, you can delete old .mcr files.
