Create your own filesystem and mount it as either a logical drive or folder. Dokan (https://github.com/dokan-dev/dokany)

Below a simple command line to mount a zip archive on X:
mount.exe /r test.zip /l x /x proxy_7zip.dll

Mount.exe is a generic code/binary independant of the filesystem you wish to create.
The filesystem is implemented in a proxy/dll.

Source code and binaries is available here.

7zip proxy example is here.

NFS proxy example is here.

I had done a few proxies for ImDisk in the past based on the libyal libraries (vmdkqcowvhdewf).

This time, as the VDI image format is quite simple, I made my own proxy for VDI images.

Imdisk + Discutils could achieve the same except that discutils requires .Net 4.0 which is not always available.

As always the command line :

« server » -> devio –dll=proxy.dll;dllopen shm:test_proxy c:\temp\freedos.vdi
« client » -> imdisk -a -t proxy -o shm -o ro -f test_proxy -m x:
Use the start command in front of devio if you want to stuff it all in one batch.

A demo to run a encrypted xored encrypted PE within the memory of another PE (and therefore possibly bypass anti virus softwares)

See https://github.com/erwan2212/XOR-freepascal about xoring / encrypting a file.

Code is currently set to use cmd.exe (x86/x64) as target host.

host32.exe/host64.exe are also provided in the zip if you wish the modify the code to use a « neutral » host.

Source code and binaries can be found here.
