[Gvsig_english] saving project storing relative path names to layer sources

[pvmstg]

Hi Chris,

Unfortunately I do not agree with you.  We are stuck with win...  
until.... We try related and fixed path.  For us... related path make  
it difficult and impossible to use.  We often use old project to  
start new one but... new project means new folder for that projects  
so relatives doesn't do the jobs.  Also... all is in the scale of the  
user... We use gis on few computers with on server for data but many  
programs on each computer.  When we need to use outside that network  
it's easy to maps data the same way by allocating letter the same ways.

Also... I haven't try to move project betwen my pc and my mac so... I  
can't imagine how a relative path can handle multiple systems syntax.  
y:/data/qc_20M/... and /Users/pvmstg/Documents/data/qc_20M

So for me the two choices is needed and, like I said in my post, with  
a good paths handler like in Xtools, everyone will be ok.

In an other subject, if gv_sig whant to extend it's user base, more  
it can use data from old esri project, more it could be accepted.   
For one, even with all it's advantage gv_sig won't be attractive if  
we can't use file geodatabase (not the personal one link to acces).   
Maybe changing to pyton database is a better way to go... but at our  
scale it's not something we go foward to... so...
