'Out of memory while expanding memory stream' error - APK Image Extractor

[languid canopy]

I keep getting this error while trying to save extracted sprites to my PC - it had no trouble actually extracting them but trying to save the images to my PC or my external hard drive gives me this error every time, and I struggled to find a relevant explanation when googling it. The game I'm trying to get sprites from is 'Alcatmist', and there are iirc about 1200 images it's trying to save to my hard drive which has about 30gigs of storage free. I'm admittedly not very tech savvy so apologies if there's an obvious bit of troubleshooting I should have figured out here...I'm just hoping someone else has experience with this and it's an easy fix rather than an annoying one lmao 🙏 thanks in advance 🫡

how much RAM do you have?

apks are basically a compressed file, so changing the file extension to .zip will let windows extract the file (alcatmist.xapk -> alcatmist.zip) you can also use winrar o 7zip and it should work too
since it's a xapk instead of an apk (without the x) it will contain some other files and an apk file where those assets are stored (you also need to change to .zip that apk file to extract it with the windows builtin extractor)
if the game is made in unity you can open the assetbundles in some assetstudio fork. if not i think those files will probably be in .png i believe
