So I can’t test this for you now. (I do most everything on a Mac.)I’ve done a quick Google and a couple of ext2/ext3 drivers for Windows. One seemed open source and current <https://sourceforge.net/projects/ext2fsd/ >. One seemed low-cost and current <http://www.partition-tool.com/easeus-partition-manager/linu >. There might be others.x-partition-manager.htm They look simple to install and use.The other alternative – which is what many of us have on our Mac and Windows systems – is to download and install the free and open source Virtual Machine Manager “VirtualBox", then install the free and open sourced “Ubuntu" Operating System. Suddenly you are a Linux person. It may not be the thing to do now as you are trying to finish a project, but it only takes a few minutes to install each, then open the Terminal and put in the commands. It will take a few seconds with a hammer figuring out how to steal the USB drive from the Windows system to allow the Linux system to write to it, and another few to figure out how to create a share folder on your Windows drive to the Ubuntu, but it isn’t rocket surgery.My actual recommendation is to find a friend who can do this for you. Or wander the local college with a sign on your chest. It will take them seconds, plus the few minutes to transfer the data from one drive to the other.How big is your DCP that you need to put on the USB drive?C J FlynnOn Jan 10, 2017, at 19:48 000PM, Joseph Verrico <jjverrico@gmail.com> wrote:Thank for the information. I was hoping I could format a USB memory stick to EXT2 on my Windows machine and then copy the DCP file structure onto that EXT2 formatted USB memory stick. I don't have Linux on my Windows machine. I don't know Linux.

But there are some that don’t and the festival seems pretty specific about what they want. They do that because there is only one formatted drive specification that all cinema systems must use.That is the EXT2 that Leslie mentioned.And, make certain that if someone makes this drive for you that they make the inode size 128, since that is in the DCI and ISDCF and SMPTE specifications.And, if the drive was originally formatted in FAT32, you’ll be limited to a 4 Gig file size, regardless of the size of the drive. First format in exFAT, or leave it with NTSF if that is what it was bought as.Here is what I do.The ISDCF document gives the following command line in a linux type system.
mkfs -t ext3 -I 128 -m 0 /dev/xddN
with xddN being the drive ‘name’, which is most often something like ‘sdb1’ – you can find that name by the command
Then unmount withsudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL sudo umount /dev/sdb1And here are two other formatting commands that work. Myself, I prefer the last one since it allows me to name the partition as it is being made.
sudo mke2fs -t ext3 -I 128 -L DCPs 0 /dev/sdb1 – slightly different command set
sudo mkfs.ext3 -I 128 -m 0 -L your-chosen-name-of-drive /
dev/sdb1 – this one adds a disk name (change "DiskName" to 'my_dcp_drive' or whatever name you want to give it) while formatting and partitioning...change that 'sdb1' to the proper partition number.Formatting the disk is not so quick – Those Superblocks might take a few minutes to assemble.
Follow up by giving permissions to the drive with: (755 is usually recommended, but I use 777 for myself)
sudo chmod -R 777 /media/Your_Login_USER_NAME/yo
ur-chosen-name-of-drive You might find that you need to change ownership
sudo chown owner:owner /media/owner/your-chosen-name-
of-drive I usually put my name twice, such as 'cj:cj', then '/media/cj/ctt_dcps'
I hope this helps. I’d hate you to have a black screen after getting this far. Good luck. Tell us how it worked out and what you ended up doing.C J FlynnOn Jan 10, 2017, at 15:45 000PM, Leslie Hartmier via DCPomatic <dcpomatic@carlh.net> wrote:______________________________No, the platform you use to create the DCP is not relevant.

HelloI've used DCP-o-Matic on a Windows machine to create a DCP for a short film I made. Worked great. I entered the short film in a film festival and got accepted. They are asking me for a Linux compatible DCP. Do I need to create the DCP on Linux for it to be Linux compatible?ThanksJoseph_________________
