How to make files CONTIGUOUS

Nearly all payload files need to be contiguous (this applies to all types of E2B USB drives - Removable UFD or Fixed-disk).

If an .ISO file is below 500MB (default limit) and is not contiguous, E2B will often try to copy the contents to a contiguous file (\_ISO\CONTIG.ISO) first so that it can be booted successfully. This can be quite slow! For more details about CONTIG.ISO see here.

E2B can also boot some linux ISOs that it recognises by name, without needing them to be contiguous (ISOBOOT). For more details see here.

Persistence files (e.g. \ubuntu-rw) and .imgPTN files need to be contiguous.

Most .WIM and .VHD files do not need to be contiguous.

To avoid any 'not contiguous' error messages from E2B, double-click on the \MAKE_THIS_DRIVE_CONTIGUOUS.cmd file on the E2B USB drive to run WinContig and make all E2B files in \ and under \_ISO on the USB drive contiguous - OR - run RMPrepUSB - CTRL+F2 to run WinContig on the whole drive instead.

For more information see this page.

Tip: You can copy the *.cmd files from \_ISO\docs\WINCONTIG to the root of the E2B USB drive if you wish. Then you can double-click on any one of them to run them.

  • \MAKE_THIS_DRIVE_CONTIGUOUS.cmd (works on \_ISO and files in \ - i.e. runs WinContig twice)
