Instead of creating longer filenames, try creating a tree like folder structure e.g IP address (192.168.0.1) |_ UserLoginName (if authentication based) or GUID based |_ PC1 |_ Cam1 |_ DatetimeFormat.jpg Computer follows instructions, if you able to identify the camera manualy then apply that in code Hope you got the point

You can use GUID ( a 16 digit characters), allot them an alias name like (near window, in front of table1, whatever best suits you to identify) then do your stuffs. BTW, if you can share the project scenario we can have better solution as well but you can try above .
