Should I remove CONTIG.ISO from Easy2Boot?

As you may know, \_ISO\CONTIG.ISO is a 500MB blank file which is included in the Easy2Boot download.

The CONTIG.ISO file is only used when a payload file is not contiguous but when E2B needs it to be contiguous. E2B will then copy the entire original payload file to the CONTIG.ISO file. This can take some time and it is done each time you boot to that same payload file.

I never actually use this feature and I suspect most Windows users do not use it either.

When you first make an E2B drive, this large file needs to be copied over to the USB drive and this can take several minutes on slow pen drives. The file also takes up 500MB of space on the USB drive which is never used as long as you always run \MAKE_THIS_DRIVE_CONTIGUOUS.cmd first.

So, my proposal is to remove the CONTIG.ISO file from the E2B self-extracting download file in the next version of E2B (v1.99c).

However, the .zip E2B download file (which is used by linux users to prepare an E2B drive) will still contain a 500MB CONTIG.ISO file.

If a Windows user still wants to use the CONTIG.ISO feature, they simply have to create a \_ISO\CONTIG.ISO file (I can provide a small batch file which will create a file of any size).

Please let me know if you think this is a bad idea ASAP, otherwise I will remove the CONTIG.ISO file in the next version.
