CRSPSift Options - Environment Scanner
Use the Environment Scanner tool search your computer for CRSP databases and automatically combine them into valid environments.
Folder Hint Paths
By default, the Environment Scanner looks for databases in a set of pre-defined locations, called Folder Hint Paths. The Folder Hint Paths provided with CRSPSift are C:\crspdata (the default install location for CRSP databases) and C:\ crspdata\Sample 3.21 (the location of the sample datasets provided with the CRSPSift software). Each time CRSPSift launches, the Folder Hint Paths are search for newly installed databases. When new databases are found by the Scanner, any valid environments based on those databases are presented to you to select and add to CRSPSift.
If your databases are installed outside the default locations, you can add your own Folder Hint Paths to guide the Environment Scanner’s search. Click the Add button next to the list of paths. Next click the Browse button and choose the directory where you would like the Scanner to search for databases. Click OK to add the directory to the list.
To delete a Folder Hint Path, select it from the list and click the Delete button.
The Environment Scanner’s Scan Options allow you to fine tune how its scan is performed. The default behavior for the Scanner is to search defined Folder Hint Paths, scanning the top level of those folders for valid databases.
If you would like to search a directory without adding it to the list of Folder Hint Paths, click the Scan Specific Location checkbox and then the Browse button to locate it.
After setting the appropriate Scan Options, click the Start Scan button to activate the Environment Scanner. When the scan begins, the Start Scan button is replaced with the Cancel Scan button. Click this button at any time during the process to halt the scan.
The time it takes for a scan to complete depends on the number of directories scanned.
