💾 what to download?

download link	is it good?	description
copyparty-sfx.py	✅ the best 👍	runs anywhere! only needs python
copyparty-en.py	✅ also good	same but english-only, no i18n
a docker image	it's ok	good if you prefer docker 🐋
copyparty.exe	⚠️ acceptable	for win8 or later; built-in thumbnailer
u2c.exe	⚠️ acceptable	CLI uploader as a win7+ exe (video)
copyparty.pyz	⚠️ acceptable	similar to the regular sfx, mostly worse
copyparty-en.pyz	⚠️ acceptable	english-only, no smb-server
copyparty32.exe	⛔️ dangerous	for win7 -- never expose to the internet!
cpp-winpe64.exe	⛔️ dangerous	runs on 64bit WinPE, otherwise useless
bootable usb	┐(ﾟ∀ﾟ)┌	a surprisingly useful joke (x86_64)

• except for u2c.exe, all of the options above are mostly equivalent
• the zip and tar.gz files below are just source code
• python packages are available at PyPI
