如果您使用 Microsoft Teams 进行视频会议,则有时可能需要清理缓存文件并删除驻留在许多子文件夹中的残留数据。
您可以调整上一个示例中的代码来进行清理:
1 2 3 4 5 6 7 8 9
# the folder that contains the Microsoft Teams data $parentFolder = "$env:userprofile\AppData\Roaming\Microsoft\Teams\*" # list of subfolders that cache data $list = 'application cache','blob storage','databases','GPUcache','IndexedDB','Local Storage','tmp'
# delete the folders found in the list Get-ChildItem$parentFolder-Directory | Where-Object name -in$list | Remove-Item-Recurse-Verbose
如果您具有管理员权限,并想为所有用户删除缓存的 Microsoft Teams 数据,请按如下所示更改 $parentFolder:
# the folder that contains the subfolders to remove $parentFolder = $env:userprofile # list of folder names to remove $list = 'scratch', 'temp', 'cache'
# delete the folders found in the list Get-ChildItem$parentFolder-Directory-Recurse | Where-Object name -in$list | Remove-Item-Recurse-Verbose-WhatIf
functionNew-DynamicFunction { # creates a new function dynamically $Name = 'Test-NewFunction' $Code = { "I am a new function defined dynamically." Write-Host-ForegroundColor Yellow 'I can do whatever you want!' Get-Process }
# create new function in function: drive and set scope to "script:" $null = New-Item-Path function: -Name"script:$Name"-Value$Code }
# this function does not (yet) exist: PS> Test-NewFunction Test-NewFunction : The term 'Test-NewFunction' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
PS> New-DynamicFunction
# now the function exists: PS> Test-NewFunction I am a new functiondefineddynamically. I can do whatever you want!
