Linux:
mount -t cramfs -o loop cramfs.img /mnt/cramfs

Windows:
There probably aren't any IFS drivers that support cramfs. There might be some tool to extract the contents of one like a .zip file.

Steps

1. Download cramfs-1.1-1.tar.bz2 from http://ftp.uni-kl.de/pub/windows/cyg...-1.1-1.tar.bz2
2. Extract the contents of cramfs-1.1-1.tar.bz2 into a directory
3. You can see cramfsck.exe and mkcramfs.exe under bin\

Run these tools under command prompt:

cramfsck.exe - To test and extract cram contents into any other directory
mkcramfs.exe - To create a new .cram file


Example:
Extract Contents:

c:\cramfs\bin>cramfsck -x c:\cram\temp\ c:\temp\temp.cram

This command will extract the contents of temp.cram to c:\cram\temp\


Create a .cram file:

c:\cramfs\bin>mkcramfs C:\cram\contents temp.cram

This command will create temp.cram file.

Note: use -h option for help for both commands.

Hope this helps
