## API documentation
* [Drive API - Files](https://developers.google.com/drive/v3/reference/files)

## Definitions
* [`<DriveFileEntity>`](Drive-File-Selection)
* [`<UserTypeEntity>`](Collections-of-Users)

```
<SharedDriveID> ::= <String>
<SharedDriveName> ::= <String>
<SharedDriveEntity> ::=
        <SharedDriveID>|(shareddriveid <SharedDriveID>)|(shareddriveid:<SharedDriveID>)|
        (shareddrive <SharedDriveName>)|(shareddrive:<SharedDriveName>)
```
## Display empty folders
```
gam <UserTypeEntity> print emptydrivefolders [todrive <ToDriveAttribute>*]
        [select <DriveFileEntity>]
        [pathdelimiter <Character>]
```
By default, empty folders on My Drive are displayed. Use `select <DriveFileEntity>`
to select a Shared Drive or an alternate starting point folder on My Drive or a Shared Drive.

By default, folder path components are separated by `/`; use `pathdelimiter <Character>` to use `<Character>` as the separator.

## Delete empty folders
```
gam <UserTypeEntity> delete emptydrivefolders
        [select <DriveFileEntity>]
        [<SharedDriveEntity>]
        [pathdelimiter <Character>]
```
By default, empty folders on My Drive are deleted(purged). Use `select <DriveFileEntity>`
to select a Shared Drive or an alternate starting point folder on My Drive or a Shared Drive.

By default, folder path components are separated by `/`; use `pathdelimiter <Character>` to use `<Character>` as the separator.

## Empty the trash on My Drive

gam <UserTypeEntity> empty drivetrash <SharedDriveEntity>
```
## Delete contents of My Drive

The following commands will delete the contents of a user's My Drive.

This is not reversible, Think before proceeding.

### Method 1
* Generate a complete list of files/folders that a user owns; this gives you a record of the files/folders that will be deleted. 
* This list may be quite large.
* Delete the top level files/folders; orphans will be deleted.

Show current drive usage.
```
gam redirect stdout ./DrivefileUsage.txt user user@domain.com show drivesettings
```
Generate an initial list of files.
```
gam redirect csv ./InitialFileList.csv user user@domain.com print filelist fields id,name,mimetype,basicpermissions,parents fullpath showdepth orderby name
```
Purge top level files/folders; includes orphans.
```
gam config csv_input_row_filter "depth:count=0" redirect stdout ./PurgeTopLevelFilesFolders.txt multiprocess redirect stderr stdout csv ./InitialFileList.csv gam user "~Owner" purge drivefile "~id"
```
Generate list of remaining files/folders; this list should be empty; investigate if not.
```
gam redirect csv ./FinalFileList.csv user user@domain.com print filelist fields id,name,mimetype,basicpermissions,parents fullpath showdepth orderby name
```
Show updated drive usage.
```
gam redirect stdout ./DrivefileUsage.txt append user user@domain.com show drivesettings
```
### Method 2
* Generate a list of top level files/folders that a user owns.
* Delete them; orphans are not included
* Generate a list of remaining file/folders (orphans).
* Delete them.

Show current drive usage.
```
gam redirect stdout ./DrivefileUsage.txt user user@domain.com show drivesettings
```
Get list of top level files/folders.
```
gam redirect csv ./TopLevelFilesFolders.csv user user@domain.com print filelist select rootid fields id,name,mimetype depth 0
```

Purge top level files/folders.
```
gam redirect stdout ./PurgeTopLevelFilesFolders.txt multiprocess redirect stderr stdout csv ./TopLevelFilesFolders.csv gam user "~Owner" purge drivefile "~id"
```
Get list of remaining files/folders; this list will typically be empty but will list orphans if they exist.
```
gam redirect csv ./OrphanFilesFolders.csv user user@domain.com print filelist fields id,name,mimetype,parents fullpath showdepth
```
Purge top level orphan files/folders; sub files/folders will also be deleted.
```
gam config csv_input_row_filter "depth:count=0" redirect stdout ./PurgeOrphanFilesFolders.txt multiprocess redirect stderr stdout csv ./OrphanFilesFolders.csv gam user "~Owner" purge drivefile "~id"
```
Generate list of remaining files/folders; this list should be empty; investigate if not.
```
gam redirect csv ./FinalFileList.csv user user@domain.com print filelist fields id,name,mimetype,basicpermissions,parents fullpath showdepth orderby name
```
Show updated drive usage.
```
gam redirect stdout ./DrivefileUsage.txt append user user@domain.com show drivesettings
```
### Method 3
* Generate a list of top level files/folders that a user owns.
* Delete them; orphans are not included
* Generate a list of remaining file/folders (orphans).
* Delete them.

Show current drive usage.
```
gam redirect stdout ./DrivefileUsage.txt user user@domain.com show drivesettings
```
Get list of top level files/folders if desired.
```
gam redirect csv ./TopLevelFilesFolders.csv user user@domain.com print filelist my_top_items fields id,name,mimetype
```
Purge top level files/folders.
```
gam redirect stdout ./PurgeTopLevelFilesFolders.txt redirect stderr stdout user user@domain.com purge drivefile my_top_items
```
Get list of remaining files/folders; this list will typically be empty but will list orphans if they exist.
```
gam redirect csv ./OrphanFilesFolders.csv user user@domain.com print filelist fields id,name,mimetype,parents fullpath showdepth
```
Purge top level orphan files/folders; sub files/folders will also be deleted.
```
gam config csv_input_row_filter "depth:count=0" redirect stdout ./PurgeOrphanFilesFolders.txt multiprocess redirect stderr stdout csv ./OrphanFilesFolders.csv gam user "~Owner" purge drivefile "~id"
```
Generate list of remaining files/folders; this list should be empty; investigate if not.
```
gam redirect csv ./FinalFileList.csv user user@domain.com print filelist fields id,name,mimetype,basicpermissions,parents fullpath showdepth orderby name
