# Location of Files

These folders are the default locations for saving specific types of files. For example, screen capture files that you save are, by default, saved in the \Screen Images subfolder. You can always save files to any folder that you wish including those on a network or external drive.

To protect you user files, it is recommended that you backup this folder to an external or network drive.

The following subfolders exist under the %USER_DATA_DIR% folder:

- Adapter Definitions
- Colorgrade-Grayscale
- De-Embedding Networks
- Documentation Results
- Jitter Data
- Limit Lines
- Limit Summaries
- Masks
- Patterns
- Presets
  - ClockRecovery
  - CTLE
  - DFE
  - ElectricalSIRC
  - FFE
  - JitterThresholds
  - RandomOperator
- Protocols
- SCPI Scripts
- Screen Images
- Setups
- SNDR
- S-Parameter Data
- User App Menu Items
- User Functions
- User Measurements
- Waveforms

--- | --- | ---
Adapter Definitions | . | :
Colorgrade-Grayscale | Saved eye-mode database files (.cgsi) that usually contain eye-diagram data. These files can be loaded into eye memory. | :DISK:EYE:SAVE :CGMemory:FILE:LOAD
De-Embedding Networks | Saved de-embedding network files (.tf4) files created using function's 2-port and 4-port de-embedding operators. Using remote programming commands, you can load but cannot create and define networks. | :FUNCtion:PARameters:DEMBed:FNAMe :FUNCtion:PARameters:DDEMbed:FNAMe
Documentation Results | Saved Documentation Wizard report files (.zip). Documentation files can be configured and saved from the GUI. Remotely, they can be configured but not saved. | :DISK:DWIZard:FNAMe
