ℹ️ this upgrade is a one-way ticket

your up2k database (.hist/up2k.db), used by the e2d filesystem indexing feature, will be upgraded to a new format which older copyparty versions cannot read.
no action is necessary to upgrade to this new version; but if you need to downgrade:
- A backup of each database will be created automatically, named up2k.db.bak.SOMETHING.v5. If you need to downgrade to a previous version: Shutdown copyparty, delete these files: up2k.db up2k.db-shm up2k.db-wal and then copy up2k.db.bak.*.v5 to up2k.db

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
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)
