Hi
I am using Libreoffice 6.0.1 when I open *.vsdx and then save as either .odg or fodg.
I cannot reopen the ,odg or .fodg
.odg
Read Error.
Format error discovered in the file in sub-document content.xml at position 2,3385(row,col).
.fodg
General Input/output error.
Works fine on the Mac.
Cheers Vin
