I have a program that needs to load about a thousand files, all variously nested inside one master folder. I have code that does this without any problem. It scans the folder, and loads all the files up one by one, recursively walking its way through the folder structure. But I need to save where these files are, in a Prefs file. Again, I'm doing this OK, by storing the path for each file. However, if I move the master folder, all the paths change. I have code that traps this, and re-indexes the master folder if it detects a change in location. I have never used aliases, though, and I wondered if their use could improve thew way I handle the master folder and its enclosed files. Any suggestions and / or observations would be welcome. Phil.
