c# - Updating my application avoids me to get my old files -

i developing desktop application using c# winforms. creating files , folders on directory application runs at. deploying application using click once approach. problem everytime update application creates new root folder run at. , won't able use files anymore. workarounds that? thinkin of creating folder @ "c:\mycompany\myapplication" reachable , breakable. happy hear other advises or knowledges favor me :)

you should store files , folders in user's application data folder. can path folder statement:

string appdatapath = system.environment.getfolderpath(environment.specialfolder.applicationdata); 

you should create folder in path application , store there.

there of course other solutions, point should not use application folder, since indeed change everytime publish, and bad practice several other reasons (data backup, etc.).
