Save As Layer File: Let us save with Absolute path... - Esri Community
I found out the hard way that MAPX and PAGX files do not save using absolute paths.
This is bad.
I say this because MAPX and PAGX files are supposed to be references to data, meaning I should be able to send them to anyone who can see the data and they should be able to pull it up correctly.
However, since both these files use relative paths, if I, for example, move the files to re-organize my Templates folder, they get broken and I have to re-create them (since, in addition to not being able to edit LYRX files through catalog, we can't do it for MAPX and PAGX files.
Please give us the option to save these template files using absolute paths.
