can non-bmp and non-wav files be used/compiled as resources with ex4?

 

https://docs.mql4.com/runtime/resources

I was wondering if it was possible to compile other file types as resources within ex4 file.  like png, zip, dll, etc.  So everything can be packaged in one ex4 file :)

 

I tried with other files but compiler refuses.

Only other thing I found that might work was example on how to pack indicator as resource inside EA.
