Server OS: Windows Server 2008 R2 64-Bit Client System: Windows 8.1 64-Bit We operate a small office setup with a server and about 8 clients. The network drives we access have always been compressed: under HDD Properties>General Tab: 'Compress this drive to save disk space' is checked. Due to a MYOB-esque program issue we were advised we should try unchecking that option; decompressing the HDD. This was done to the networked drive with Administrative User from a client PC running Windows 8.1. This was cancelled at one instance then the operation restarted. After some time the operations were completed and the drive was no longer compressed. However, numerous, but not all, .docx, .xlxs, .jpeg, .pdffiles became inaccessible adding .encryptedafter the file extension. i.e.Example.docx.encrypted Merely deleting the.encryptedextension results in you being able to open the file but only shows the jumble of symbols typical of encrypted files. Does anyone know how to resolve this issue? Thank you in advance.
