Clear example follows. By the way â/â and â\â are not interchangeable⦠in Windows FileSystem requires â\â to work properly: | fn l fileStream | fn := 'temp\',UUIDGenerator next asString,'.txt'. Transcript clear; show: fn; cr. fileStream := ((FileSystem root) / fn) writeStream. fileStream ifNil: [ Transcript show: 'Fail to create writeStream'; cr ] ifNotNil: [ Transcript show: 'Opened' ]. fileStream nextPutAll: 'Casimiro de Almeida Barreto'. fileStream close. fileStream := ((FileSystem root) / fn) readStream. l := fileStream upToEnd. Transcript show: l; cr. ((FileSystem root) / fn) delete. This example creates a file named c:\temp\380cafd3-c80a-0d00-b117-0a8a049bf78d.txt and I was able to write âCasimiro de Almeida Barretoâ to it. And then open the file in the read mode and read âCasimiro de Almeida Barretoâ from it. But⦠((FileSystem root) / fn) delete returns a: âFileDoesNotExist: Path /âtemp\380cafd3-c80a-0d00-b117-0a8a049bf78d.txtâ. Apparently the problem is at WindowsStore(DiskStore) delete: --- Este email foi escaneado pelo Avast antivÃrus. https://www.avast.com/antivirus
