reading about some sort of resource editor to allow editing of resources

Hello,
If you need to access dynamic data in a single file, maybe my code may
help you. Basically it is a filesystem that can be embedded in a single
file, so you can create, delete, open, read, write and seek any
individual file inside. The "problem" is that in write mode only a test
filesystem (not very usefull), Excel filesystem and ZIP filesystem are
supported. The ZIP one is cool but to rebuild the final ZIP once updated
it could need some temp files as it can not be edited in place. Maybe
the BCF (Binary Coumpound File, the one that Excel uses) is a good
choice as it has quite small initial tables (like a format) and grow as
more data is being added.
The virtual filesystem can be mounted over an encrypted TFileStream
derivate to allow transparent encryption of the whole virtual
filesystem. It can read also raw images in FAT16 and FAT32 but can not
write them.
