-### Store ZIP seek index into save file
+### Reading large files in ZIPs
 When a DOS games opens a large file and wants to read some data from near the end of the file,
 DOSBox Pure needs to decompress the entire file to do that. This can be most noticeable when mounting
-CD-ROM images from inside ZIP files.  
-Afterwards there is an index buffer which will be used to decompress random locations of the file
-and file access will be much faster.  
-This index buffer is stored into the game save file to avoid having to slowly rebuild it
-every time the same game is launched.

 ## Building
 DOSBox Pure has no dependency requirements besides a C++ compiler and the standard library.
