Are the plugins at least compatible from older PEBakery to newer PEBakery versions
Yes
Assume I have a *.Script file with unknown relationsship.
Apart from the obvious name in most cases ie
BurnDataCD_XPE.scriptline 3 of the file will have Type=XPEPlugin or Type=Plugin if written to current standards
nb. a large number (most) of XPEPlugins also have a related file ie
BurnDataCD_XPE_File.Script to which the initial downloaded
app file is encoded into for subsequent runs, unless you use the
Update button to download a newer version of the App.
How can I check whether this *.script file belongs to WinBuilder or to PEBakery?
Win10PE SE and Win10XPE are two of the projects available from here
Winbuilder and PEBakery are both builders
Not forgetting the Live System Pro project (LSP) that uses the .srt file extension (not .script)
