be my guest :good:

but this has nothing at all to do with this... to simplify the differences
you're extracting ruu,
im comparing 2 versions of a custom rom (which are usually zipped and thus require extracting)

different kind of extracting im afraid

The main task was, edit system.img (mount and create sparse image), but of course without extracting it from the RUU, it was impossible to achieve

ok, I understand that there is offtop, I just wanted to ask for advice, where do I make a thread, because the tool supports multiple devices htc ..

thanks for understanding

Thank you!

Suggestion

@Thunder07 Nice Work Sir
Just One Suggestion... Can't We Use BSDIFF/IMGDIFF Tool To Make Smaller OTA Updates?

What Your Tool Does Is, It Compare Two Folders And Then Extracts/Copy-Paste Different/Newer Files into "OTA" Folder... Thats Good, But If We Use BSDIFF Tool Then The Generated OTA Size Could Be More Than Five Times Smaller Compared To Original OTA... What Do You Say About it?

Actually i Was Working On The Same Type Of Project But My idea is To Use BSDIFF Tool in My Project To Make OTA Size More Smaller... Android is A Bit New To Me... Now i Need Your Opinion For This... Thanks Alot

a single byte change in an apk or something will prevent patching...

Yes You Are Right But Normally Files Don't Get Modified By Themselves... This is The End User Who Can Modify Files And He Should Not Do This if He Wanted To install New Updates, Same Rule Applies For Stock ROMs...
The Developer Of The ROM Can Also Leave A Note So The End User Will Be Aware Of it...

Or Atlease BSDIFF/IMGDIFF Tools Can Be Added As An Optional Feature, Because What i Think is, OTA Creator Becomes inefficient For Those CM/MIUI/Lewa ROMs Because Even Their Weekly Updated ROM Contain Dozens Of Files With Different MD5 Hashes, And Then The Generated OTA With This Tool Can Exceed 100MB... One More Benefit Of Adding BSDIFF is Developer Can Make OTA Update if He Gets The New Firmware Or New ROM Backup From Somewhere Else...

IMGDIFF Tool is Alot More Better Than BSDIFF Tool... i Checked Each And Every Corner Of The Web But Not Able To Find IMGDIFF's Win Port... i Asked Some Developers To Compile it For Windows Because i Dont Know Linux... But Still Stuck With BSDIFF Tool...
This Will Be Helpful For Alot Of Peoples if You Can Add These Tools in Your OTA Creator... There is A Guy in XDA Who Compiled IMGDIFF For Win, But Thats Not Working For Me... if You Know Where i Can Get IMGDIFF For Win, Pease Share The Source i Will Be Very Thankful To You...
