Why save change log file into executable?
It's 164,170 bytes big! |

What's the problem with it being in the executable?
Windows doesn't load the entire exe into memory, only the bits that get used are loaded on demand
If you don't read the changelog, it isn't loaded off disk

if executable compressed by upx lzma then it certainly will |

And all the other reasons exe compressors are more trouble than their worth
Seriously what on earth is the point these programs?
Nice hijack of someone else's thread though.....

the same why we compress BMP into PNG

exe/dlls are not pictures or videos
They do not need to be completely loaded into memory - only the parts used are loaded into memory
Multiple instances of an exe/dll will reuse the same memory pages saving total memory use
Background services can preload just the parts used into the os's memory space for faster startups
exe compressors break all this, for very little benefit
It's even sillier when talking about size of virtualdub vs the size of 1 video
But good luck with the awesome amount of free disk space you gain by compressing virtualdub
Just think of all the things you can do with those free mb's

* Virtualdub exe is not compressed (image)
* Virtualdub is very compact for the amount of functionality it has.
(WinFF: 54MB; StaxRip:140MB; RipBot64: 200MB)
* If the change log were a txt file, it would be take the same disk space anyway.
* At least it's not in Unicode  |

let meowmeow answer two posts in 1 click
exe/dlls are not pictures or videos
Who said "pictures"? I call program - image in view by CPU - if don't contain other things like menu texts inside.
They do not need to be completely loaded into memory - only the parts used are loaded into memory
but they don't need to be compiled into exe either.
Multiple instances of an exe/dll will reuse the same memory pages saving total memory use
good point, but I don't see how it works.
Background services can preload just the parts used into the os's memory space for faster startups
Windows prefetcher? That's why my windows runs slow?
Just think of all the things you can do with those free mb's
I'll compress 17.5 GB in 20771 exe/dll files into 6 GB and save for meowmeow 11.5 GB for SailorMoon'2014 series.
* Virtualdub exe is not compressed
Not my problem (image).
* Virtualdub is very compact for the amount of functionality it has.
not not not
VirtualDub 1.4 - 1.33 MB (uncompressed) 504 KB (compressed)
* If the change log were a txt file, it would be take the same disk space anyway.
So I can just delete it. |

Let me add a couple of more reasons for this:
The first is that adding compression specifically for the changelog would take time, and I already find it hard to get enough time to work on VirtualDub as it is. Therefore, doing so would take time away from working on other parts of the program.
Second, regarding UPX whole-executable compression -- I actually used to do this, but I had to back it out because tons of stupid antivirus programs automatically flag programs compressed with it as a virus. The result was that I just got lots of complaints from people about "why did you give me a virus???" even though there was no such issue. NirSoft has an excellent writeup about all the problems this causes: http://blog.nirsoft.net/2009/05/17/antivir...all-developers/ .
In the end, what it comes down to is that the size amounts we're talking about are pretty small compared to the data that VirtualDub works with, less than a single video frame, so it hasn't been a high enough priority for me. Sorry. However, you can always compress the executable with UPX yourself to save disk space, such as if you've got it on a small USB stick.
